ToastyMallow-Gaming As a welder I have tried all kinds of auto darkening hoods from the harbor freight cheap ones, Lincoln Electric 3350, and Miller 9400. I sold all of those and went back to an old Jackson flip up hood. Why? Because you can't beat the clarity of a real piece of glass. Also getting replacement lenses is cheap and easy to do so.

Seriously! I had to build a side shield into my mask to keep from getting blinked by the freaking safety lights on the carts. If I knew then what I know now, I'd probably have glued an IR filter over the damn things!

When I got my first auto helmet back in the early to mid 90's other people also were using them and I did mess with them with a TV remote. another thing that will trigger them is low bay lamps. Back then I paid over £400 for the helmet and another £400 odd for the breathing equipment that went with it.

Hello AvE,
I did another approach to measure the time between input pulse (IR) and the time to darken the helmet. I uploaded this video-answer on my channel.

I am using an IR-LED for triggering and then measure the light signal with a small solar-cell. I also compared a cheap one with a proper 3M Speedglas 100 V.

Greetings and have a nice Christmas!

Why don't you just take a capacitor and short it? This is why I think this could help: cables work like antennas, without the welding cables you will have less emission. There could be some hf noise going through your wall power, both the welder and oscilloscope are connected to the same power source.
Then: shield all your oscilloscope cables with alu foil.

With the old flip lens helmets I would flash myself at least once almost every time I welded. Now I'm a bit of a newb when it comes to welding, and I don't do it very often, so it's very difficult to get back in that rythm that a pro would have. I also suffer from an unsteady hand, so I'm always waiting until the last possible second to flip it down. Then because of my shakes, I accidentally strike an arc and burn my flipping eyeballs every time. I hated those things. Got one of the Harbor Freight special auto ones about 2 years ago and I will NEVER use a flip helmet again. Haven't flashed myself once since.

balisticsquirel - 3 years ago
Here's why i choose a passive lens : LCD filters rely on a matrix of floaty crystal doodats to create the darkening effect. And those sound like physical things which in between them would let full light intensity through yet create an overall (general) darkening effect. So individual rods and cones would be getting 'lazered' while the visual field appears dark overall.
Is there any way to test this?
Maybe with a continuous light source in locked location, an LCD filter locked in position, and something like old-school photographic paper to catch the rays coming through? If it 'develops' a pattern of bright spots then there's differential pass-through.

While on the topic of welding ... I have a mobile welding rig, miller trailblazer 325efi. My cables are on alumareels, 125’ of 1/0 cable spooled up on a 12” diameter spool. The manual for the alumareels says to unspool the entire length of cable when welding. Am I destroying my equipment if the cables are left on the spools and I’m only pulling out what I need to reach my work? If I’m running at 130 amps I don’t bother to un spool the cables but at 180 amps I do. Am I doing damage to my machine?
Martin Jedrzejewski
Martin Jedrzejewski - 3 years ago
John Francis Doe , I am aware of the heat issue. If it’s a hot summer day I unspool all 120’ even if I’m welding off my tailgate. The positive and negative are on separate spools, 4’ away from each other. Am I creating a MRI effect on my pliance? Cables are approximately wrapped 14 per layer and 4or so layers deep on the spools, the centre of the spool is a 3” diameter pvc pipe. Heat issue aside do you think I am damaging my welding machine by not unspooling every time I weld even if it’s only at 130 amps?
John Francis Doe
John Francis Doe - 3 years ago
Martin Jedrzejewski The cables heat up from all the ekectrocity running through them. If still packed densely on a spool, they get hotter and the plastic isolation will wear out faster (or in extreme cases catch fire). If the forward and return wires are wound separately (not together) there's also the magnetic field being multiplied by the number of turns around the spool, but I guess that's less important than the usual heat issue.

If it is triggered by an IR LED, why not use an IR LED from a TV remote and and the complimentary receiver behind the visor, two channels on the scope - one for sensing the source and then the other to see the response???? Plus take the jeeslus thing apaaart and probe the frig out of it!?

From miller's website, copy/pasted from their high end helmet.
Electromagnetic arc sensing
One available helmet technology that can help improve productivity is electromagnetic arc sensing. This option can be especially beneficial for outdoor welding or in applications where the welding operator has an obstructed view.

On helmets without this technology, the position of the welding operator’s head or an obstruction can block the sensors on the lens, preventing the lens from darkening. Bright sunlight during outdoor welding applications can also cause the lens to darken before the operator is ready.

With electromagnetic arc sensing, the sensor picks up the magnetic frequency of the welding arc to eliminate any interference issues. The lens will darken only during welding and stays dark throughout the process — even in bright sunlight or when there are obstacles between the sensor and the arc. This reduces operator downtime for helmet adjustments or repositioning of the work piece.

Oh FFS AvE, close but no cookie. You established in the last vid that it can be triggered by a IR led, you used 2 IR led as detectors but did not think to use a IR led as the trigger (no need for cocking around with making a filter). Imagine this: 1 IR led transmitter mounted 3 inch from 1 IR led detector with both being hooked up to the e-smellascope. Turn on led and note the delay in the receiver, put the filer in between the two and repeat..... done. No need for playing with the noisy high voltage electron spitting phallic substitute.

"is it a particle or is it a wave?" it's neither. It is what it is. "particle" and "wave" are words that describe phenomena that are familiar to us in the macroscopic world. They don't make much actual sense in the quantum level or even the atom level (friend of mine says intra-molecular interactions are also mostly quantum-based so maybe even at the molecule level), where 'stuff' behaves as it does behave.

TylerLeeds111 - 3 years ago
The method used in those masks for blocking visible spectrum light is most likely an LCD panel. Specifically, it's most likely a TN type (Twisted Nematic) LCD because they're cheap and have the fastest switching time.

An LCD consists of chains of crystals floating in a liquid. The crystal geometry means that they're translucent (ish) in one phase but nearly opaque when twisted 90 degrees. A voltage causes the crystals to twist but that's not instantaneous. 2ms is actually pretty fast. The amount of voltage dictates the amount of twist and thus the amount of light passed by the panel.

2ms is also periously close to the single-frame time of that RX100 at 240FPS. Probably too close to rely on the results.

Could you use a photocell (like from a nightlight) and put it behind the welding glass. Hook it to your Oscilliscope and you should be able to measure the time between voltage peak and fall-off to determine the switching time on the panel.

If the shade never transmits any IR or UV how do you expect to test it using an IR LED as a detector? The detector behind the shade will never have anything to detect.

Also, to avoid the noise, use an IR LED to trigger the shade rather than the welder.

So, on the front place an IR and visible LED in parallel side-by-side, and behind the shade place a visible light detector. Point the IR LED at the shade's sensor, and the visible LED at your sensor through the shade. Cover the mess to avoid stray light. Turn on the power to the IR/Visible pair and also trigger the scope. Show the result of the visible detector on the scope.

A "BPW24" is sensitive between 300 and 1100nm.

The specs for that very tested auto darkening filter (Vista 3000) is avaliable at:
Which lists 0.1 msecs light to dark time. It also has this: Slow to darken:
• If the filter has not been used for a day or more, the circuitry will
enter a sleep mode. It will wake up when tested or when you begin
welding. Note that the first time, it may darken to a lighter shade
even though set for a darker shade. After the first time, it will darken
to the correct shade setting every time. It is recommended to
test your ADF prior to welding.
• Colder temperatures can slow the switching speed of any ADF.
Once the helmet warms up from the welding process, the switching
will increase to rated speeds.

So I don't think the high speed camera is up to task to measure its reaction time when it is warm and operating as it should. Your measuring different times is indication to this I think, because on time should be same regardless of the "delay" setting. And this Vista 3000 is actually not a fast one. I have a lowly Lowe's Kobalt for my once or twice in life time usage, it lists 50 micro seconds light to dark time. And the visible light spectrum can hurt your eyes too, in the end they are all photons and have energy.

The "delay" on auto-darkening lenses controls how long the lens stays dark after you stop welding, not how quickly it darkens initially.
PhaseP1 - 3 years ago
Correct. The "light to dark" is same and from what I have been reading in the provided specs are in the order of sub milisecs. The very lense he is testing has 100 micro sec light to dark time listed. Newer ones list 50 micro seconds or even less light to dark times.

A few cents for improving the filter and testing with the o-smell-oscope..
When dealing with low signal strengths like IR leds as sources, then use film or ceramic capacitors, and pF to nF cap values, this allows the tiny currents from the led to charge the capacity.

I think all you need is a photodetector behind it. It will spike as the visible light from the welder reaches it and dim when the mask activates

Hey ave , long time lurker , first time commenter, but in regards to your filter setup, and specifically the capacitor, I’ve learned in my few years of building performance racing drones , which are very susceptible to noise , the length of the capacitor leads is not supposed to exceed more than 1mm, and wires are suggested if you need the length. Reason being is , those leads have a ton of resistance and only are really effective at >1mm, as typically they are intended for surface mount
Boss Nacho FPV

Boss Nacho FPV The only ones intended for surface mount are the ones with surface mount pads instead of legs. The legged ones are either for general use or for through hole mount through a board which is up to 2.5mm thick, though 1.6mm (1/16 ") is the most common. Anyways, the resistance in his setup is dwarfed by the actual resistors and his biggest problem is probably the magnetic pickup by the area of the gap between his wires.

I'm confused by this whole slow and fast setting that you're talking about and I've been a welder for almost 20 years. The only thing I can think of is the delay setting which only affects how fast the lens returns to clear after you finish. I've never used a Lincoln hood either so that might be it too.

if you have an electrical noise problem - just don't use actual welder.
you can trigger it by IR diode. (plug it to the oscilloscope generator chanel)
and for shield - use photo diode and flashlight.
(so on the one chanel you have a setup that measures shield opacity for visible light. and on the generator chanel is a trigger fo shield)

olleollesson11 - 3 years ago
If you put one UV-led directly and one behind the shield you ain't going to get a signal from the one behind the shield due to the shield always shielding UV no matter it's triggered or not.
But if a noise free environment is achieved I guess you can just amplify to compensate for the filter, but then again a welder is not a perfect apparatus for a noise free environment :-)

Nice video. YTer electronupdate uses solar cells from cheap calculators as light sensors in combination with the scope to detect (non)visible flicker of LED's in his teardown videos. That's a pretty high speed application.
The solar cells output a usable voltage to detect by oscilloscope. I'm not sure if it's high enough to get above the noise of that welder. I have not tried it for myself. Thank you for your uploads.

to the delay thing, its not related to any noise filtering at all, it simply is the LCD screen (wich is the thing that makes it dark) needing time to switch on. 1-2 ms is realisticly the fastest you gonna get out of an usual lcd screen. but doesnt really matter, even if it were 10 ms time, there would be no harm since as you found out, all radiation gets blocked anyways weather the filter is triggering or not. may get uncomfortable because you get that visible light flash all the time, but i bet 10ms are not enough to really notice

you also cant compare one 200ms flash to 100 2 ms flashes, because your eye will dissipate the heat from a 2 ms flash in no time but one 200ms flash could potentially hurt more. i mean, its an eye, its made to absorb light to a certain extend, you dont run around with a welding helmet when going to a bbq in sunny weather conditions... but it would still be funny to do so!

Even visible light is bad for you when it is very bright. It is good to keep it as short a flash as possible. However the occasional flash of 200ms with a manual glass is much worse than 100 flashes at 2ms with the auto units. Also much more likely.

That is apples to eggs comparison. The TV refresh rate is challenging due to the number of pixels it has to refresh, i.e the whole picture needs to change with each. These filters are going from off to on in whole display at once. The specs given for these are actually sub miliseconds. I read somewhere actually they have to provide the light to dark delay specs to be able to sell in US, so they all have them listed in the product manuals what not. You can google and find.

Just a note about the filtering. Filtering will cause delay, as you mentioned the 2mS is pretty fast for having any filtering as it is.

Also, consider that using an RC filter would have added a lot of delay in your scope measurement.

I think you should do the measurement using the photodetector and the scope. You only need the one detector and can use the welder as your source. Without the screen, in place, you can test to set the scope and trigger. Then with the shield in place you should see the trigger and the wall of noise which should drop sharply when the screen triggers. Measure the time from the first spike (trigger) and when you see the level drop due to the shield.

You may have too much EM noise getting into your photodetector leads then signal from the LED sensor. To mitigate that noise, make sure all the sensor wiring is well away from the welder cables. Ideally, you only have the LED attached to the scope probe, keep the probe cable far away from the welder cable.

Also, try switching to the X1 mode on the scope probe. This lowers the probe impedance which can help reduce the EM coupling. You will have to bump the gain on the scope up by 10 but that should be better.

Best way to piss off a welder? Take the forklift with the strobe light on it and leave it running nearby. All the welder's hoods will darken with every flash of the strobe! The first time I experienced it, I thought for sure my hood was broken!

Back when I used to work for a living instead of click for a living, I welded pipe. The booth mainly a 3-sided weld curtain with forklift aisle was right behind the curtain facing me. Many times I'd be tigging and the helmet would stop darkening because the torch was behind something and the flashing triggered the helmet instead.

Can you test if the Harbor Freight $50 auto darkening welding helmet blocks all IR/UV light? I've been trusting my peepers to one for a couple years and have to wonder if I'm doing long term damage with the cheapo helmet.

Just looked a Lincoln and no mention of UV/IR protection that I could find...perhaps I missed it.
PlatypusVomit - 3 years ago
Dave, I use #61612 (might be an older version of that number, actually, as I think mine's not quite as rounded as that one, but it's that red pattern), and yes it says that, but I've come across flat out lies in HF's sales pages before, and the 'UV/IR protection' line doesn't even say '100%' or 'complete protection' or anything like that, so I'd be surprised if it was blocking 100% of UV/IR. I've been figuring on getting an expensive high quality one when this one dies, but it's been good for a couple of years so far and I'm a bit of a cheapskate when I have no reason not to be.

My garage fluorescent lights ( 8 foot tubes, not fancy CFL ) trigger my tig welding helmet, but not my mig helmets. The mig helmets ( harbor freight ) work great for mig, but refuse to darken with a tig arc. I had to buy a higher quality auto darkening helmet ( don't recall which brand ) to consistently darken on the tig. Sometimes, if the tig arc is partially blocked, the tig helmet won't trigger, and I'm staring through flash burn for the next half hour.

Please test the dirt cheap chinese made auto filters one might find at ebay. I got a face shield helmet thingy that cost less than $20 and for my purposes it seem to work. But does it? My welding skills consists of some seagull turds on metal maybe once a year, so I cheaped out.
2009dudeman - 3 years ago
The super cheap ones do work, largely they are the same filter and circuity as the expensive ones. The real difference is the quality of the build. A proper quality hood will stand up to years of use and abuse, whereas the chinese harbor freight will get you through welding class, and around the garage, but thats all it will do. The straps suck, the pads aren't usually washable and stink after awhile or straight up disintegrate, they are made of flimsy plastic and lack a lot of nice features. Some of the things forgotten on cheap hoods is quality of the shade selection knob, breath direction, and safety glasses space.

The only problem with LCD screens is the delay (however short). Any delay at the point of arc creation causes green flash spots on your retinas, Like a mini visual shock wave, they don't last long, but can get in the way of delicate pieces or awkward welding positions. I find lining up my rod, then making contact, with your eyes slightly turned away, prevents the centre of the retina from being flashed. A similar analogy with driving at night and not looking directly at the opposing headlights. your vision is clearer after they pass you.

So, can we have the TIG UV, IR and visible levels in terms of "suns"?
I mean, let's say it's 1000 suns at 0.5 meters. A blocking factor of "100%" on a 3-digit reading could be 99.6% rounded up, meaning we're still getting 4 "staring-at-the-sun"s-worth of exposure.

That's where I really thought he was going with the scope idea. One channel scoping the "triggering" diode on the welding side of the glass, and the other channel scoping the waveform from the "sensor" on the eyeball side.... Apply voltage to the triggering diode, capture the event in single shot mode on the osmelloscope, and measure the time between the pulse generated and when the voltage drops to 0 on the other side.

wrap your welder in tin foil, covering as much of it as possible and you will block out a lot of its noise. Or put it in a metal box of some kind. Faraday cage that shit. Alternatively, you can shield your smellyscope and its tentacles with some tin foil to keep the welder noises out.
Lunchbox Productions
Lunchbox Productions - 3 years ago
The problem is that the leads themselves are basically huge antennae, that's a big reason that when welding you're supposed to attach the earth clamp close to where you're welding to prevent turning the whole part and area between the leads into a magnetic field.

I think the only way you could shield the noise from a welder would be to toss it into the ocean or move the power button to "off".

AvE - You should take a look at the 3D Glasses used for '3D TVs'. I'm wondering if they use a similar technology as the lenses essentially alternate turning opaque in sync with the TV. This is so your left eye views the 'left image' shown on the TV and then changes for the right eye. I'm guessing its around 30hz per lens as your TV is likely showing a 60hz image.

Jeff NME actually, they are circularly polarised. One left hand, one right hand. This is so you don’t lose cross-polar discrimination if you tilt your head a bit.
Jeff NME

If you mean 3D glasses like the ones at the cinema, then it's basically two polarising filters (just like sunglasses) with the left and right set at 90degrees to each other.
Each lens blocks the image to the other, because the projected image is polarised differently for left and right.

I can trig my auto darkening screen with a flashlight or a strong enough visible light source (I guess they give off IR radiation as well). Connect one osmelloscope channel to the light bulb/LED and the other to a photoresistor and voila, accurate measurements of the delay time in visible light. Although as our beloved uncle stated at the end, the bad stuff is permanently blocked anyway. 
Merry christmas to all ye brothers of the oily cloth.
R1pperB - 3 years ago
The IR led is called IR for the spectrum it emits (and also the wavelength it is most sensitive at detecting). There are VL-blocking IR LEDs which appear black and block visible light. However the clear epoxy casing allows visible light to be detected as well.
boggisthecat - 3 years ago
I was thinking that he’d use two LEDs, one in front (emitter) and one behind (detector) — but it appears that another idea was in the offing. If the shield passively blocks 100% of IR then it wouldn’t work, but it would probably be 99.9...% or such. So maybe enough IR through for the detector LED to spit out a signal? (Or maybe not. I don’t know what the conversion efficiency of a LED used as a detector would be.)

Thermal cameras work by reading Infrared, right? If you look at something hot through the polycarbonate or whatever will it appear colder than it is?
NGC1433 - 3 years ago
Usual window glass blocks most thermal radiation. It is opaque to most IR. It will look like it is room temperature. Like the wall would look like. It has no reason to appear colder. Shiny metals can appear colder if they are in reality hot, because they don't emit a lot of IR but reflect the ambient IR which tricks the camera to think it's cold. I don't think glass reflects a lot.
Damiaan Jeurissen
Damiaan Jeurissen - 3 years ago
When I was in university they showed it once and the infrared camera sees polycarbonate as completely black, no IR emission
boggisthecat - 3 years ago
Rock Automatik
Yes. Depending on the detector(s) used, you may get a much reduced signal or total signal loss. I would think that an IR camera would just give you an ambient temperature indication in this case, rather than freaking out and asserting that everything in frame was at absolute zero. (The emissivity settings would come into this, too.)

CO2 blocks IR too, which is the basis for the anthropogenic global warming problem. (The IR from the ground can’t be radiated back out into space. This is useful because the Earth would be a snowball otherwise, but more CO2 means more heat trapped.). The whole area of EM radiation is interesting but can be difficult to understand intuitively, because it isn’t within the normal operating parameters of our monkey brain architecture.

It had no clue what was going on past the polycarbonate square right in front of it. Interesting stuff.
