Mig welding question

[Russell Ashley]

I'm using a Lincoln Weldpac 100 with .025 solid wire and 75/25 sheilding gas. One question that I don't remember seeing an answer to is how much pressure to run for the gas. I usually set mine to 20 psi and it seems good but I have also set it anywhere from 10 to 20 with also good results. I work in my garage with no or very little air movement so that isn't a problem. I am just curious about what you guys typically use as there seems to be a lot of experience and skill here on the forum.
