Hello I have recently started MIG welding in school and have been using 75 argon/25 Carbon dioxide. I have been welding vertical up on a T-Joint and have failed to penetrated the inside of the joint all my penetration is on the walls I have been using a weave pattern to go up. My wire speed has been any where from 177 to 250 and voltage 18 to 20. No matter how I adjust my heat the penetration still isn't there.
