I am experiencing a consistent but intermittent arcing issue with the mig gun liner. This happens generally at the start of the weld just as the trigger is squeezed. The wire always arcs in the liner at the point of entry from the drive wheel. I has welded itself inside the liner and I cannot remove the wire from the liner. This problem has now ruined 3 liners and has obviously cost both time and money.
A call to Miller provided the suggestion to replace the gun. Bernard only issues a 6 month warranty on their guns so a new gun is about 350 bucks.
Has anyone else experienced this problem? Or are there other possible causes and cures?
