No, not one machine. There are two basic types of power supplies, constant current, and constant voltage. Constant current is your basic stick welder, which with high freqency added along with current control, becomes a TIG welder. I have several of those, need to get down to one hopefully, maybe keeping the 330 on the shelf as a backup. The one i'm making the cart for is the target CC welder, the Syncrowave 300. The other type, constant voltage, is your basic MIG. Most people have a MIG with a feeder integrated in the box. I have MIGs with external feeders, in this case, a Miller S-52E, which works great and is pretty industrial. The power sources are convertered CP200/300 from 3 phase to single phase. It's called the Dave Kamp conversion. You can get welders that do all processes, those are always inverter type. I specifically don't want an inverter welder, one because i'm not doing enough welding to see a savings on the power bill, and two, i don't want a welder that can spontaneously puke a board one day and take out ALL of my welders. The older welders i like don't usually have boards to go belly up.
My plasma is an inverter, but an OLD one, which has discrete components on the boards, you can actually fix those when they go bad. New ones, you just throw a board away and put another $1000 board in it, IF you can get one. We all know by now i don't like throw away society...
