I have a hobart 175.
What should the regulator be set at for optimum performance.
I'm practicing to build my cage.

What wire? I sugest a good S6 .030 I prefer the lincoln wire. I run about 25 on my flow meeter. Did you look on the inside of the side cover? there are baseline peramiters provided by miller on a sticker in that location. Did you buy it new? if so Watch the video:flipoff2:

I see you asked "what pressure?", but I assume you mean flow rate. I use a Smith flow meter (the kind that has a ball that floats when gas is flowing) set at 20 CF/HR. I use a C25 mix, which is 75% argon and 25% CO2 (kwrangln has it backwards in his reply, and it's also CF/HR , not CFM). You want to be out of the wind for any kind of shielded gas welding, be it TIG or MIG. If you're outside in a breeze, use flux core.

Doesnt matter what type of wire you use. If you have a breeze, you'll get porosity just the same.
Agreed.

I wouldn't build my cage in the wind, but if outdoors is your only option, flux core on a fairly calm day is ok.
