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’.

or electrode with skin or wet
clothing.

ground.
