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

Why argon? Your best bet will be CO2 or a 75/25 CO2/argon mix. Anywhere from 15-30 cfm depending on breeze and position will be fine.

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.

DOH!!! Guess my damn coffee hasnt kicked in yet, sorry about the bad info. My brain knew the answer, had trouble getting the info to my fingers while typing.

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

Thanks for the info
Yes it's a mix 75-25
indoor mostly
video no got
I don't know any welders sot my learning curve is pretty steep
that's why i'm practicing

flow rate , thanks for the correct term

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.

What guage wire would be best for .120 wal dom

Unless you're using innershield:flipoff2:
