TIG welder

One thing I might ask is it a foot pedal control???
Mine has a foot pedal and I use my foot to go up and down with the current level. That means you can change the heat as you go along and I think this is most important. This gives the best control. some of the cheaper units are controlled by a dial on the machine and some on the handle itself (I think NOt sure)
I will concur with everyone else once you learn to tig it is hard to go any other way for sheet metal,
