View Full Version : Mig Welding Stainless
I have a Miller 180. I weld alot of steel and some aluminum and wanted to start doing some stainless. What do I need to do a good quaility job(gas,wire)? How does stainless compare to steel? Any tips/tricks?
Thank you all in advance.

It's not all that different than mig welding mild steel. It's just a little less forgiving as I'm sure you will find out. You will need trimix gas to short circuit. I usually bump my volts +.5-1 compared to what I would use on mild steel. We mostly use Esab OK Autorod LSI 035 wire where I work.

Forgot this. SS likes a super short stickout. So if your nozzle isnt flush with your tip grind it back until it is.

Don't buy the el cheapo wire either, get some Loncoln, Hobart, ESAB,etc something with some degree of quality control beind it.

youll need a tri mix gas
So tri gas, good quaility SS wire and grind the tip back?

the tip should just be flush with the nozzle. it's good for SC on mild steel tool. I just mentioned it because you can get away with the tip being recessed with mild steel in a lot of cases. A lot of bad habits that go unnoticed on mild steel will frustrate the hell out of you on ss.
