Hello there welders. I am currently working on getting into the local plumber/pipefitters union. I have a test this Saturday. My issue is the root pass. I am welding 2 inch carbon steel pipe and using a stainless filler. I just have problems running consistent. I am putting the root in at 78 amps. Then i was bumping my amps by 10 or so but was getting alot of suckback. So i backed it down to what I am putting the root in at. I tend to panic thinking i am gonna blow keyholes. Would you folks possibly walk me through it or even give me some pointers? Thank you for your time, have a great day.
