Problem Recommended actions
The wire burns into the contact tip
• Make sure the size and type of the current tip and liner are
suitable for the filler wire.
• Make sure the wire liner is clean.
• Make sure the wire liner does not make any steep loops.
• Check the motor current level. If the current is too high, there
may be problems in the wire liner.

rolls may affect soft filler wires, such as aluminium and flux-
cored wires.
