just bought a miller 180 and spool gunnot sure weather to buy a argon tank or a 75/25 argon co2 tankdont really wanna buy both. can i do alnumin with 75/25?thanks
Reply:nope, gotta have pure Ar for aluminum and some sort of Ar/CO2 mix (75/25, 80/20, 85/15, etc) for steel. It's an expensive hobbyIf you cannot convince them, confuse them. Harry S Truman
Reply:Hello bonez10, unfortunately you will need either argon, argon/helium, or helium. Argon is the most economical, however, if you are trying to weld thicker sections with your machine the ar/he mix will provide additional useable heat for better penetration. Helium would not be a preferred choice due to cost and higher flowrates, thus cost issues. Best regards, Allanaevald
Reply:Cheapest way to go about it is buy an argon tank for aluminum and a CO2 tank for solid steel wire, or forget solid steel wire and go with self shield fluxcore wire instead, which doesn't need gas then you only need to buy one tank, argon for the aluminum.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:One other thought. You can always swap out your cyl for the gas you need especially if you have a small cylinder. Not the most efficient way, but if you don't do a lot of alum it might work well. I used to get away with only one cyl for quite awhile. I'd keep it full of 75/25 for steel and then if I had an alum job, I'd swap the 60 cf for one of argon and then swap it back to 75/25 when finished. I'dd try to save up the alum jobs to do all at once, and try and time it for when my cyl was low any ways so it didn't cost as much to change gases..No government ever voluntarily reduces itself in size.
