I used Matts basic numbers from another thread and cut some 1/4 and 3/16 aluminum. I want to say 60amp tip, AV 142 and speed 65 IPM. I used the regular shop air and had great cuts. I did a sign for the inside of my shop and messed around with a couple name plates for freinds. I look forward to seeing what you come up with. Remember I use unsheilded ring with sheilded tips.
