installed overlay. (With no overlay

 

 

 

 

on the machine or an invalid over-

 

 

 

 

lay, the machine will have no out-

2. Check to see if the Limits or

 

 

 

 

Setup overlay is installed on the

 

 

 

 

front panel. These two overlays

 

 

 

 

can not be used for welding.

 

 

 

 

3. Check for proper input voltage

 

 

 

 

(per machine nameplate).

 

 

 

 

4. Make certain the reconnect

 

 

 

 

panel is configured properly.

 

 

 

 

5. Check that when the trigger is

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, con- tact your local authorized Lincoln Electric Field Service Facility for technical assistance.
