1 Help 1 Display

Indicates a malfunction in the primary power circuit. If this display is shown, contact a Fac- tory Authorized Service Agent.

2 Help 2 Display

Indicates a malfunction in the thermal protec- tion circuitry. If this display is shown, contact a Factory Authorized Service Agent.

3 Help 3 Display

Indicates the left side of the unit has over- heated. The unit has shut down to allow the fan to cool it (see Section 3-3). Operation will continue when the unit has cooled.

4 Help 5 Display

Indicates the right side of the unit has over- heated. The unit has shut down to allow the fan to cool it (see Section 3-3). Operation will continue when the unit has cooled.

5 Help 6 Display

Indicates operation at maximum input cur- rent. The unit has a maximum allowable input

current limit. As the line voltage decreases, the required input current increases. If the line voltage is too low, the output power is limited by the input current. When this limit is reached, the unit automatically reduces out- put power to continue operation. If this display is shown, have a qualified electrician check the input voltage.

6 Help 8 Display

Indicates a malfunction in the secondary power circuit of the unit. If this display is shown, contact a Factory Authorized Service Agent.

Check and replace line fuse(s), if necessary, or reset circuit breaker (see Sections 4-3and 4-4).

 

 

 

 

 

 

 

 

Check for proper input power connections (see Sections 4-3and 4-4).

 

 

 

 

 

No weld output; meter display On.

Input voltage outside acceptable range of variation (see Section 4-5).

 

 

 

 

 

 

 

 

Check, repair, or replace remote control.

 

 

 

 

 

 

 

 

Unit overheated. Allow unit to cool with fan On (see Section 3-3).

 

 

 

 

 

Erratic or improper weld output.

Use proper size and type of weld cable (see Section 4-6).

 

 

 

 

 

 

 

 

Clean and tighten all weld connections.
