This FlameWeld model works very well. I like the pilot arc feature. It works on that. Two weeks earlier I had bought another brand from Revain that was slightly cheaper. It also had a pilot arc, but it didn't work properly when you increased the air pressure. I sent it back and ordered this one, at the risk it would work better. This FlameWeld did not disappoint, I'm keeping it. In addition, consumables from other brands wore out quickly after little use. You are not on this one. I'm still on the first set after completing my project. It cuts 1/4 inch thick steel very well. I had a small 3/8 piece that I tested it on and it cut it too. I wanted to test this for 1/2 but couldn't find anything to try. Another brand may not have been paired with the correct flashlight. I do not know. This burner works perfectly.
