ArcOne T240-10 Tradesman Horizontal Auto-Darkening Filter for Welding Helmets, 2 x 4.25 x 0.2

Awesome unit! I installed it into a $20 mask https://a.co/d/h2mnCSx and the fit was perfect. The mask has a flip front where this auto-darkening filter went. There is another piece of clear class in front of the dark filter so the Tradesman unit is well protected from splatter while welding. When I flip the front I still have a clear glass shield in the mask's opening so I can see better when clearing the slack. It was worth spending a little extra compared to the cheaper no name brands to get something from a reputable company like AcrOne. I'm a beginner welder and this helped me a lot to be able to strike an ark reliably and have both of my hands available to steady the electrode and maintain a straight weld. I was struggling with the transition between striking an arc, lowering the filter and maintaining the weld going properly. Then restart the ark at the right spot if I lose it. This fixed the problem nicely. The darkening transition is instant and if the arc stops I immediately see where my bead is to restart from the right spot. Shade 10 is enough for welding stick up to 5/32" and 160A. See the attached image with recommended shade numbers. I'm not going to weld over 100A so Shade 10 is perfect. Thank you, ArcOne for offering this affordable filter for hobbyists!

At work we have a XVX Hobart helmet that retailed for about $279.00 when it first came out. It's a good professional grade helmet, but for a beginning welder it had so many adjustment parameters it took me getting flashed a bunch of times before I finally figured out what was going wrong and how to tune it properly. It can be frustrating to be learning to weld and learning how to setup a helmet at the same time. In contrast, for my home use I revived an old Fiber-Metal pipeliner helmet by inserting this filter into it, and I was amazed how easily it worked by comparison. There are no settings to get wrong. You just use it, and it becomes very second nature. I was NEVER flashed. Not even once. And it didn't matter when changing from using it outdoors and indoors. In comparison, the XVX Hobart helmet required adjustments when the overhead lighting conditions changed (outdoor/indoor). I think for the professional user that can appreciate all the adjustment nuances that an expensive helmet can provide, they can be happy spending the big bucks rockin' the Speedglas, Miller Elite, etc., etc. However, if you want a low cost solution, and you want the auto-darkening feature to work every dog-gone time, use this filter in a helmet that somebody's cast aside for one of those gourmet ones. I did and had enough money left over to get a nice Eswing E3-WC welder's chipping hammer (really awesome) and some tricked-out Keen steel toe boots so tough I kicked out some dents in a metal garbage can with them. Welding has a lot of start-up costs if you're a beginner, and it's all about stretching those coins to get everything you need and being gratified like that. I'm currently building a small plywood box to use as a carrying case for this helmet. It will have a clear Lexan lid so that when you store the helmet facing up light will enter in and keep the auto-darkening filter charged up. Was this a good purchase for me? Yes, it was. I'm very happy.

I bought this lens back in 2015, it lasted me almost 4 years. It got me through weld school and into the field makin money, all processes/all positions, thousands and thousands of welds. I have a lot of love for this 2x4. Across the board it does well and I think for most youngins the 10.5 shade is a good middle ground. I do believe it is the best 2x4 auto dark for the money. Incredible value. Now sometimes the manufacturing process can change but the one I bought from this supplier 4 years ago was reliable. Some things to note... Depending on the process/rod size/heat/etc this may not be for you For example: if you’re welding aly in a shop at 300amps all day don’t buy this. You will have a bad time. If you’re runnin 5/32 or bigger 7018 all day it may be too bright for you If you’re runnin 1/8 6010 on small pipe it may be too dark for you (that’s what I have found and switched to the arcone 10 shade) If you need to grind a bunch, maybe use it with a flip front, otherwise it will blink on you all day If you’re weldin out of position/tight quarters with TIG it can sometimes block the sensors and you get blinked on, it’s quite frustrating That being said... If you’re learning to weld/in weld school/doin classic field welding this lens is the right choice

The clarity of both, inactive and active modes is great. Inactive mode is bright and clear, dark mode is dark enough to never feel assaulted by light, never need to avert my sight from a bright arc, and yet not so dark so as to not see the surrounding environment around the arc. Perfect vision no matter if darkened or not. The autodark speed is ultrafast and since u maintain peripheral vision in both modes the transition of your visual attention is seamless. The undarkening is delayed slightly, not too long, about half a second or a second. Great for trouble starting or maintaining an arc, as theres no madness of the lens going dark and undark with the arc like crazy. The tint is amazing. I posted pictures. Ive got polarized raybans and oakleys and id trade them for glasses with this tint. It is yellow with a HINT of green. Though the live red puddle looks amber/orange under the lens. The shade is great 👍. It is enough for 1/8th 6010 & 7018. Absolutely no overdarkening and no underdarkening. I'm buying another just to have ready or to gift.

Update: Initially I had some trouble with this lens, The clarity is excellent but I was getting flashed. I think it may be the nature of two sensor lenses (that they're not as quick as larger four sensor lenses.) After months of using this lens it's proven reliable I've changed from a two to a four star rating. I still get blinked from time to time but overall I'm happy with the lens.

This lens was purchased for an old leather hood helmet that I use when welding overhead. (Well, actually when I crawl under my vehicles, and weld.) I tested it for a few minutes after I got it installed in the old hood, and it works great. Very happy with it. I paid the $53.97 for this lens as opposed to $14 to $25 for others in the search list mostly because the reviews for this one were very high. A one star reviewer stated the lens they had received was green instead of amber? Hmmm? Well, I didn't notice the description stating either green or amber; mine's amber. Since the original 20-25 year old leather hood had a flip-up shade, I removed all of the flip up mechanism, and installed the auto-darken lens in place of the clear lens, so the hood is noticeable lighter, which is cool. This modification works pretty good considering I had to accommodate 3 thicknesses of lens that replaced a single clear lens. One thing I found somewhat disturbing was the clear lenses that I tried to buy at the local welding shop. I was told OSHA will not allow them to sell clear glass lenses, only polycarbonate plastic POS's. Apparently, if the clear glass lens takes a hard enough hit, it could shatter and spray the user with glass shards. Ok. So, I bought a couple plastic lenses (40¢ each-cheap) just to finish the installation of my great new auto-darkening lens. I tried hard not to touch the plastic while installing them. When I got them anchored, that GD plastic crap had attracted some dust, and I scratched it trying to get it clean again. What junk!! When my acceptance testing was completed, I went back to Amazon to find some clear glass replacement lenses, and OMG!! Unbelievable high prices! $2.23 each as an "add on item," or $3.39 each with "free" shipping. After some surfing, I finally found some for a reasonable price at www.gradyshardware.com, where I bought 25 Forney 56801 clear glass, non-hardened lenses for $24.75. That's 79¢ each + $5 shipping. (Save $50, just in case you're in the same boat.) If anyone whom read this far finds them at a lower price, comment on this review and let everyone know. Thanx!

I really do like the lense. Its easy to use. Only thing is the LISTING image as of now is wrong, so I uploaded a current image. NEW update. 3 months later. Lens fared well against 2800 degree heat of a glass furnace. My high heat fibermetal hood has a large indent in it due to the heat. Lens still works fine, even though it took some damage. Hopefully the company can replace it. Overall a great buy for what it can stand up to and continue to work!

Like this for my hood that I use for sick welding allows to fire up without arcing out.

I’ve been using this bad boy for over a year now, cleans up well, never been flashed unless it was my own stupidity. Fits in nicely to the fibre metal helmet I own. Way better quality than the $80 princess auto helmets! Will be buying another

la compre porque ArcOne es garantia de calidad y porque el precio es muy barato, rapida respuesta de obscurecimiento, super ligera, facil de instalar y tiene tamaño standard lo que la hace super universal, se ajusta a la mayoria de las caretas comvencionales, MUY RECOMENDABLE

It looks clear, but it's too late to block it.

Aún no lo he podido probar pero es el producto que esperaba

love it, weld work so clear
