SHelp 0

Indicates overheating on left side of unit (displays flash between OVER TEMP and HELP 1). Unit will shutdown until internal temperature drops within operational range.

SHelp 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.

SHelp 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.

SHelp 3

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.

SHelp 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.

SHelp 5

Indicates a malfunction in wire feed system and/or drive motor overcurrent condition. Check for proper spool brake adjustment or obstructions in wire feed system. Clean or replace liner, wire guides, or contact tip.

SHelp 6

Indicates a malfunction in wire feed system and/or external drive motor overcurrent con- dition (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.

SHelp 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.

SHelp 8

Indicates a malfunction in the secondary power circuit of the unit. Check control board PC1, and primary and secondary connections.

SHelp 9

Indicates a malfunction in Pulse MIG function. Check connection between pulse board and user interface board. Replace pulse board, if necessary.

SHelp 10

Indicates a trigger error when two gun triggers are activated at the same time. Release gun triggers to clear error.

SHelp 11

Indicates a tach error when tach feedback signal is not present. Release and press gun trigger to reset tach signal. If error continues, contact a Factory Authorized Service Agent.

STip Save

Indicates contact tip is directly shorted to workpiece. Arc shuts off in this condition, and message resets when tip is not touching workpiece and gun trigger is released.

SMM 350P

When unit is turned on, this display indicates that pulse option is installed and operational.

SMM 350

When unit is turned on, this display indicates that unit is either a MIG only machine or pulse option is installed but not operational.

SJog 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.
