They did.. With the best of tips, my oxy acetylene torch doesn't cut that nice.. The biggest difference I think is that separate nozzle to blow the slag outta the way..
I didn't get a chance to try welding with it though.. For that I suspect my standard ole welding tip would be about the same, other than the pistol grip design... The thing literally weighs nothing compared to a regular torch...
Makes sense that it would use less gas too.. The oxy regulator was set to only about 6 psi and the acetylene was set about 4psi...
