Fault description and corrective actions
Overtemperature warning — The wire feeder is approaching a
critical temperature level. The weld that is already in progress
may be completed, but a new weld cannot be started until the
overtemperature warning disappears. For more information
about the overheating protection, see the "CONTROL PANEL"
chapter.
Corrective actions:
• Check the liner, clean using pressurized air and replace
the liner if it is damaged or worn.
• Check the wire pressure setting and adjust if needed.
• Check the drive rolls for wear and replace if needed.
• Ensure that the filler metal spool can rotate without too
much resistance. Adjust the brake hub if needed.
• If the fault persists despite performing these actions, try
replacing the torch.
• If the fault persists despite replacing the torch, contact an
ESAB authorized service technician.
