I think tche answer is " maybe ". Mig in short circuit transfer is
constant voltage. And TIG is constant current. But MIG is pretty much constant current in Spray Mode. Think about it. Constant stream of ionized particles. When stick welding you are using spray mode. Unless you are a really bad welder, you are not doing short circuit transfer. So there is no reason you can't do wire feed welding with a constant current supply. I have a friend ( Sorry Steve, but I really do have some friends ) who said he used his stick welder coupled to his 110 volt MIG welder when the metal was too thick for his little 110 volt welder. I did not think it would work and thought he was pulling my leg. But tried it, and it is possible. It is even possible to use a AC arc welder with a non-voltage sensing wire feed, but I think DC would be a lot better. Yes this sounds like a bunch of horse pucky, but you can try this at home. Caution if the wire feed speed is not fast enough, you might lose a contact tip or two. So start with a fairly high wire speed. Now whether the Harbor Freight welder will supply enough current, I don't know. Dan |

I've never used one!!! Dennis at Arco Welding Repair has a Hobart box that I think will allow you to interface a tig with a wire feeder. It was sitting on the floor last time I was in there. $25 takes it. Might want to call him http://www.arcowelder.com/ Gunner "Pax Americana is a philosophy. Hardly an empire. Making sure other people play nice and dont kill each other (and us) off in job lots is hardly empire building, particularly when you give them self determination under "play nice" rules. Think of it as having your older brother knock the **** out of you for torturing the cat." Gunner |
