Welding wire worn due to heavy contact pressure at the feed rollers
Remedy:
Reduce contact pressure at the feed rollers
Cause:
Wrong dimension of contact tube
Remedy:
Use a contact tube of the correct dimension
Cause:
Duty cycle of welding torch has been exceeded
Remedy:
Shorten the ON times or use a higher-capacity torch
Cause:
Contact tube has overheated. No thermal dissipation, as the contact
tube is fitted too loosely
Cause:
Tighten the contact tube
NOTE!
When using CrNi, the contact tube may be subject to a higher degree of wear
due to the nature of the surface of CrNi welding wire.

Cause:
Moisture/condensation in the shielding gas hose
Remedy:
Dry the shielding gas hose
Cause:
Shielding gas flow is either too high or too low
Remedy:
Correct the shielding gas flow
Cause:
Insufficient shielding-gas flow at the beginning or end of welding
Remedy:
Increase gas pre-flow or gas post-flow
