Help 0

Indicates shorted thermistor RT2 on left side of unit. Contact a Factory Authorized Ser- vice Agent.

Help 1

Indicates a malfunction in the primary power circuit. Contact a Factory Authorized Ser- vice Agent.

Help 2

Indicates a malfunction in the thermal protection circuitry on left side of unit. Con- tact a Factory Authorized Service Agent.

Help 3

Indicates overheating on left side of unit. Unit will shutdown and fan will run until internal temperature drops within operational range.

Help 4

Indicates a malfunction in the thermal protection circuitry on right side of unit. Con- tact a Factory Authorized Service Agent.

Help 5

Indicates overheating on right side of unit. Unit will shutdown and fan will run until inter- nal temperature drops within operational range.

Help 6

Indicates input voltage is too low and unit has automatically shut down. Operation will con- tinue when voltage is within an acceptable lower range limit (15% below acceptable in- put voltage). Contact an electrician to check input line voltage.

Help 7

Indicates input voltage is too high and unit has automatically shut down. Operation will continue when voltage is within an accept- able upper range limit (15% above accept- able input voltage). Contact an electrician to check input line voltage. HELP 7 may also in- dicate a bus voltage imbalance.

Help 8

Indicates a malfunction in the secondary power circuit of the unit. Contact a Factory Authorized Service Agent.

Help 9

Indicates a shorted thermistor RT1 on right side of unit. Contact a Factory Authorized Service Agent.

Help 15

Indicates a malfunctioning cooling unit. Unit will shut down immediately. Turn off primary power. Check and repair cooling unit compo- nents as necessary. Unit will operate when power to unit is turned off and back on.

Help 50

Indicates an overload at the power module. Reduce weld parameter settings and/or duty cycle. If error continues, contact a Factory Authorized Service Agent.
