I usually flow 15 cfpm [OOPs this is cu ft per hour, not minute} when tig welding inside with no breeze, and 20 when outside. . . I run a big bottle 220 cu ft so it lasts around 10 hours welding. . an it always runs out in the middle of a job. . .
I only use argon on the tig machine and run straight CO2 on the mig. . a lot cheaper and the welds are the same on steel. . last bottle I got of argon 220 cu ft was right at $130 from Praxair. . that is the commercial rate and bigger the bottle, the rate gets better |
