Question: What size cover plate does it use on each side?
Document: Great, used it many times and having great success with it, the dial on the side makes it easy to go from welding to cutting and back if need be, simple and the large lens makes it easy to see what I'm doing.
Got this as a present for my father who has been in the welding industry for 35+ years, but has never bought one of these. He loved it. Looks like carbon fiber, and be immediately put the decals of his favorite brand on the side. Awesome gift, works well.
Fast delivery exactly as advertised works great and I like the exterior setting adjustment on the side of the helmet. Haven't had it long enough to see how long the batteries last but time will tell. I can only hope they last as long as another helmet I have.
ahhhh  you got me! Its not really carbon fiber. No wonder it was such a steal. like  the view size, but it doesnt darken on start up. Fiddled with the settings and no change. The shade adjuster knob feels like its about to break, and its just out of the box. I could have gotten a cheaper hood with the same functionality adding a grind setting for far cheaper.
This helmet came with a broken adjustment knob on the outside of the helmet. I returned it and bought a different helmet that only uses buttons located inside the helmet. I think this is a serious design flaw affecting the helmet's usability and durability. I don't want to have to gently place my welding helmet down making sure not to drop it on the side with the knob. Or be careful when bobbing my head in and out of tight areas for fear that I'll clip that knob on something causing it to break.
I love the size of the window view and the quality of the helmet overall. It's impossible for sparks and spatter to get into the main lense thanks to the very tight outer protective lens. I'm a full time welder and the only defect about the product is that there are only two sensors on the helmet. I do a lot of out of position welding where my hands and the welding torch creates shadows that block most of the arc light and the helmet flickers on and off which can create arc eye.
Helmet material a little thin, but great for light use. Electronics perform well. Seems to be a great value for the money.
good helmet for the price - head gear either to tight  or to loose - found the trick use a rubber o ring under the adjustment nut- works great after that
I might change my review after I can actually use it. Just got yesterday the helmet takes two cr2032 batterys but mine had one dead. But I do love how big the window is on it
I do not use it all the time, just for working on my truck and other projects, but it is very comfortable, I like the adjustments availabe and the grinding mode. I also like the extra protective plastic covers for the viewing surface.
Answer: no
