Regulator pressure when welding on Aluminium?

by Steve

I have a MillierMatic 211 and would like to know what is the regulator pressure setting when welding on Aluminium. Thanks


I would guess 20-25 cfh on the flowmeter.

at about 40 psi

this is a quote from miller site...The most common shielding gas for MIG welding aluminum is 100 % argon. Flow rates of 20 to 30 CFH (cubic feet per hour) are acceptable. C25 or argon Co2 mixes are not acceptable.

thanks for posting,
