I have an old ( early 70's ) Hobart Cyber Tig 200, and cant seem to get the tig to work. The stick output is great, nice and smooth. When I try, i get the hi freq , but no real power. If I open it up all the way, it will spit and sputter for a second, then eats the tungsten tip off. I'm running DCEN, and this occurs across the current ranges.
I am testing this with an argon/C02 mix, because i dont want to lease a bottle and not have a use for it. It is the mig mix. Could this be contributing to the problem? I was also wondering if anyony has a manual for this unit, the serial # is 8RT-11607.
Any help would be appreciated-
