Argon Tank where to go?

[utahzukgonewild]

Just got my 1st welder that will do gas, So where should I go for my Argon? Need a tank does anyone know how much deposit's are say 40 cf. Also I'm told to go with a 75/25 mix, Does that sound right?
Thanx, everyone

Airgas


depending on what size welder you have you might want straight CO2..... It will penetrate better but not weld as clean as an argon mix

I got a 10 year rental on a (I think) 125 cf tank of 75% argon 25% co2 at praxair for like $150. When I ran out a few weeks ago it was about $75 for the refill. I went to the one off 300 west and 2100 south. The asian dude working the counter was patient with me as I was trying to figure out what I needed being new to welding. The difference welding with gas from flux core is awesome..
