TO SET FOR MACHINE OR REMOTE CONTROL

The output can be controlled either from the AC- 1200, the wire feeder or other remote locations.

To adjust the current from the wire feeder or other remote locations, set the toggle switch on the front of the AC-1200 to ‘Output Control Remote’. To adjust the output current from the AC-1200, set this switch to ‘Output Control at AC-1200’.

T0 SET THE OUTPUT CURRENT

Start the AC-1200 using the line disconnect switch or breaker installed with the input wiring. The red pilot light on the front panel indicates when the welder is on.

Adjust the output current from minimum to maximum within the range set by the output stud connections using either the ‘Output Control’ rheostat on the AC- 1200 (toggle switch set on ‘Panel Control’) or the wire feeder or other remote rheostat (toggle switch set on ‘Output Control Re-mote’).

TO WELD WITH MANUAL ELECTRODES

Turn the welder off, disconnect the wire feeder leads and connect a jumper between #2 and #4 on the AC-1200 terminal strip. This closes the output con- tactors making the output studs electrically ‘hot’ whenever the machine is on. Adjust the output cur- rent as described above. Cau-tion: If the wire feeder electrode cables are left connected to the output studs, the wire feeder nozzle and electrode will be electrically ‘hot’.
