Can someone give me some theory as to what is the cause of the following messy weld:
They are two supposedly clean pieces of mild steel, I tried changing current and wire feed speed, I was happy with gas flow speed. When I moved onto another edge with the same settings, and mere moments later, I got the following weld:
Which is more satisfactory and only a matter of centimeters away from the bad bit. I have noticed this behaviour on occasion, but this event was particularly prevalent over the whole weld segment. Very frustrating. Any explanations?
