Hey guys, in order to help you get the best advice here are instructions on how to post when asking for help with a welding problem. This will help others help you without having to ask for more info.
Include these things in your post:
Cup size
gas flow rate (specify lpm or cfh)
Filler rod size
amperage
AC balance if welding aluminum
what cleaning was done
And any other info you want to include
If we have to ask more questions to help you it just slows down your learning and fills up the comments with unnecessary questions. Hope this help!
