Indicates a malfunction in the primary power circuit. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
Indicates thermal protection circuitry is malfunctioning. If this
code appears on the display, contact the nearest Factory
Authorized Service Agent.
Indicates left side of unit has overheated. Unit has shutdown to
allow fans to lower left side temperature. Operation will continue
after unit is within normal temperature range.
Indicates bottom of unit has overheated. Unit has shutdown to
allow fans to lower bottom temperature. Operation will continue
after unit is within normal temperature range.
Indicates right side of unit has overheated. Unit has shutdown
to allow fans to lower right side temperature. Operation will
continue after unit is within normal temperature range.
Indicates secondary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
Indicates primary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
Indicates primary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
Indicates primary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
Indicates input primary line voltage is too low or power source
is incorrectly linked.
Increase primary line voltage to at least 90% of specified
nominal voltage.
Indicates duty cycle limit exceeded. Output stops and the cooling
fan will run. Wait 15 minutes for unit to cool. Reduce amperage,
voltage, wire feed speed, or duty cycle before welding.
Indicates button is stuck on the power source upon start up.
Fault will clear when button is released.
Indicates stuck remote contactor in TIG mode. Fault will clear
when foot pedal or control device contactor is released.
Indicates stuck remote contactor in Stick mode. Fault will clear
when foot pedal or control device contactor is released.
Indicates tach error on left motor. Check left feeder drive housing
and wire spool for obstructions. If this code continues to appear on
the display, contact the nearest Factory Authorized Service Agent.
Indicates tach error on right motor. Check right feeder drive
housing and wire spool for obstructions. If this code continues
to appear on the display, contact the nearest Factory Author-
ized Service Agent.
Indicates motor error on left motor. Check left feeder drive
housing and wire spool for obstructions. If this code continues
to appear on the display, contact the nearest Factory Author-
ized Service Agent.
Indicates motor error on right motor. Check right feeder drive
housing and wire spool for obstructions. If this code continues
to appear on the display, contact the nearest Factory Author-
ized Service Agent.
