I purchased a second hand welder off ebay today and took it home to try it out.
Whilst welding I found the wire would stop feeding and on closer examination it had burnt back to the copper welding tip. I had to file off molten steel from the tip so the wire would feed again.
Just trying to understand why this happens as it never happened on my welding course ?
Could it be that I am trying to weld mild steel with 100% Argon ?
