Description
Cable arrangement between welding power source
and Smart Feeder is preventing proper operation. Un-
coil the work and welding cables. Lay the cables
straight and close together. Cables that are first laid
out straight and close together may then be coiled
together.
Indicates wrong polarity. Turn Welding Power Source
off. Make sure that work and welding cables are con-
nected properly. (See Sections 5-2 and 5-8 for con-
nection instructions.)
Indicates current sensor is malfunctioning. If this code
appears, contact nearest Factory Authorized Service
Agent.
Indicates thermal protection circuitry is malfunctioning.
If this code appears, contact nearest Factory Autho-
rized Service Agent.
Indicates feeder has overheated. Unit has shut down

Indicates duty cycle limit has been exceeded. Output
stops and the cooling fan will run. Wait about 15 min
for unit to cool. Reduce Amperage, Voltage, Wire feed
speed, or duty cycle before restarting.
Indicates tach error on motor. Check feeder drive
housing and wire spool for obstructions. If this code
continues to appear on the display, contact nearest
Factory Authorized Service Agent.
Indicates a motor error. Check feeder drive housing
and wire spool for obstructions. If this code continues
