Welding Tips and Tricks

Hey guys, I have a quick question.... so I was welding some 1/4" plates (6 total) to a 1 inch shaft/rod (not hollow) spaced out 60 degrees apart and as the piece was getting hotter and hotter and I felt the wire in my gun getting caught up as if the liner was messed up and the sound of the welder completely changed like my settings weren't right... and so I straightened out my lead and cleaned the cup and even put in a new contact tip.. when I went back to welding it sounded perfect again but after welding another 3 inches the same problem occured... I felt the wire in the gun like it wasnt feeding properly and it sounded like shit again.. sputtering.. I checked everything out and it's not the spool or the clamps on the rollers that feeds the wire... then I welded a test piece and it was fine again but when I went to weld the shaft again the same thing happened... the sound was completely different, not like bacon frying but sputtering... so I turned down the voltage and the wfs, but couldnt get it to go away... do I just have to wait for the piece to cool or what... I dont wanna have any down time so I'm just wondering if you guys have any advice... I was using .35 running vertical downhill... any tips and advice would be greatly appreciated. Thanks in advance!

Could be arc blow caused by the magnetic field in the thick steel. There are a number of ways around this. Wrap the ground cable around the job, changing direction of welding, heating up the part (not always an option) and switching to ac stick welding. That will eliminate the issue
