Lincoln 185 tig problems

[prochargedbird]

Has anyone had problems with these units? I keep burning up red tip tungsten
unit goes into protection after 10 15 min of solid welding, and welds look like shit.

I weld aluminum and steel


Im by no meens a pro but had a Miller 180sd tig before and welded like a champ.

any ideas
Thanks

I have one and it works great.

I assume you have a problem with consumables quality or technique.

That's where I'd look first. In any case there is no intrinsic problem that I know about.

Sounds like you might have the ground and work leads mixed up.
