WARNING

ELECTRIC SHOCK can kill.

Do not touch electrically live parts or electrode with skin or wet clothing.

Insulate yourself from work and ground.

Always wear dry insulating gloves.

FUMES AND GASES can be dangerous.

• Keep your head out of fumes.

Use ventilation or exhaust to remove fumes from breathing zone.

WELDING SPARKS can cause fire or explosion

Keep flammable material away.

Do not weld on containers that have held combustibles.

ARC RAYS can burn.

Wear eye, ear and body protection.

Observe additional Safety Guidelines detailed throughout this manual.

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’.
