All directions are in reference to the
front of the unit. All circuitry referred to
is located inside the unit.
Help 0
S
Indicates overheating on left side of unit
(displays flash between OVER TEMP and
HELP 0). Unit will shutdown until internal
temperature drops within operational range.
S Help 1
Turn off primary input power and check input
voltage per primary voltage rating of welder,
and correct if necessary. If HELP 1 persists,
this Indicates a communication error
between control board PC1 and user
interface board. Contact nearest Factory
Authorized Service Agent.
S Help 2
Indicates overheating on right side of unit
(displays flash between OVER TEMP and
HELP 2). Unit will shutdown until internal
temperature drops within operational range.

Help 3
S
Indicates gun trigger was pulled and held
during power up. Release gun trigger and
clear fault condition. Also, this display can
Indicate no open circuit voltage detected
when gun trigger is pulled and no arc
detected within 3 seconds. Turn off primary
input power and contact a Factory
Authorized Service Agent.
S Help 4
Indicates gun trigger was pulled and held for
2 minutes without a welding arc established
or there is a direct short between contact tip
or wire and the workpiece. Release gun
trigger and clear fault condition.
S Help 6
Indicates a malfunction in wire feed system
and/or external drive motor over-current
condition (spool gun or push-pull gun).
Check for proper spool brake adjustment or
obstructions in wire feed system. Clean or
replace liner, wire guides, or contact tip.
S Help 7
Indicates input voltage malfunction (voltage
too high or too low) causing unit to
automatically shut down. Turn off input
primary power and check input voltage per
primary voltage rating of welder. Unit will
operate once input voltage is within
specification and power to unit is turned off
and back on.
Help 8
S
Indicates open circuit voltage is out of range.
Turn off primary input power and contact a
Factory Authorized Service Agent.
S G.CAL ERR.1
Indicates a gun calibration wire restriction
error. This error occurs if the detected wire
speed during a calibration is too slow. This
error will not prevent the feeder from
operating, but wire speed accuracy may be
compromised.
S G.CAL ERR.2
Indicates a gun calibration wire slip error.
This error occurs if the detected wire speed
during a calibration is too fast. This error will
not prevent the feeder from operating, but
wire speed accuracy may be compromised.
S Jog XXX (Wire Feed Speed)
Indicates trigger is pressed, but no arc is
detected. Wire feed speed goes to Jog wire
feed speed after 3 seconds.
