## Description

ArcOne Tradesman Auto-Darkening Filter 2-Inch x 4-1/4-Inch x 2-Inch - Horizontal is an economical, general use auto-darkening filter. Great for the do-it-yourselfer and home hobbyist. This 2X4-inch filter has a light state of 3 and single shade 10.5.

Review: Great not to have to fiddle with a flip filter! - 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!
Review: Good for beginners. Great retro-fit for cast off older style helmets. - 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.

## Questions & Answers

**Q: How long does it take solar power battery to charge**
A: There is no battery, welding produces UV radiation which powers photovoltaic cells.

**Q: i imagine when you drop this in it needs clear lens on the front right? any one installed this on a non flip up pipe liner hood?**
A: Yes it definitely needs a clear lens on the front. Your non flip up helmet will accommodate at least one clear lens and one filter lens.

**Q: After placing a lens on the outside and inside of the Tradesman lens, I see multiple puddles.  Any tips on how to eliminate that?**
A: You should not have any puddles anywhere on that lenz.  You might have the plastic lenz protectors on the other filters make sure you remove the fine  rubberized film off the lenz.  Otherwise you will have the air pockets created when they finish a protective lenz cover.  make sure there are no plastic lenz covers on any lenz.  That's why you have those bubbles. make sure you remove all the plastic lenz covers inside and out.

**Q: will this fit a 2x4 1/4 fibre metal flip front shield**
A: It fits my fibre metal pipeliner hood pretty sure they are the same size, this auto darkerner shield really doesn't go dark when grinding it only darkens on welds it's probably the best shield I've ever had way better than my speedglas 9100xxx

### ⭐⭐⭐⭐⭐ Lasted almost 4 years
*by S***R on October 17, 2019*

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
