Display Code Fault Description
H01 Primary Power Circuit Over Current Indicates a malfunction in the primary power circuit. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
H02 Temperature Sensor Malfunction Indicates thermal protection circuitry is malfunctioning. If this
code appears on the display, contact the nearest Factory
Authorized Service Agent.
H03 Secondary Circuit Over Temperature 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.
H05 Primary Circuit Over Temperature 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.
H08 Output Over Voltage Malfunction Indicates secondary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
H09 Primary Power Circuit Current Detect Malfunction Indicates primary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
H10 Primary Power Circuit Control Malfunction Indicates primary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
H11 Primary Bus Capacitor Voltage Imbalance Indicates primary power circuit is malfunctioning. If this code
appears on the display, contact the nearest Factory Authorized
Service Agent.
H12 Primary Input Line Voltage Malfunction 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.
H13 Voltage Sense System cannot measure output voltage. Make sure work sense
lead is connected between feeder and work. If this code
continues to appear on the display, contact the nearest Factory
Authorized Service Agent.
H25 Duty Cycle 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.
H26 Button Stuck Power Source Indicates button is stuck on the power source upon start up.
Fault will clear when button is released.
H31 Stuck Contactor Stick Indicates stuck remote contactor in Stick mode. Fault will clear
when foot pedal or control device contactor is released.
H40 Tach Indicates tach error. Check feeder drive housing and wire spool for
obstructions. If this code continues to appear on the display, con-
tact the nearest Factory Authorized Service Agent.
H42 Motor Indicates motor error. Check feeder drive housing and wire
spool for obstructions. If this code continues to appear on the
display, contact the nearest Factory Authorized Service Agent.
H44 Motor Low Bus 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.
If this code continues to appear on the display, contact the
nearest Factory Authorized Service Agent.
H45 Button Stuck Feeder Indicates button is stuck on the feeder upon feeder power up.
Fault will clear when button is released.
