CONNECTION OF THE K488 SG CONTROL
MODULE AND K487 MAGNUM SPOOL GUN
TO THE CLASSIC III OR CLASSIC IIID
(EQUIPPED WITH K623-1 WIRE FEED
MODULE) (SEE FIGURE C.6.)
1. Shut the welder off.
2. Connect the electrode cable from the SG Control
Module to the “+” terminal of the welder. Connect
the work cable to the “CV–” terminal of the welder.
NOTE: Welding cable must be sized for current
and duty cycle of application.
NOTE: Figure C.6 shows the electrode connected
for positive polarity. To change polarity, shut the
welder off and reverse the electrode and work
cables at the Classic III or Classic IIID output ter-
minals.
3. Connect the K867 Universal adapter to the K492
input cable as shown in Figure C.6. Connect the
other end of the adapter to the 14 pin amphenol on
the Classic III or Classic IIID.
4. Connect the K492 Input Cable to the SG Control
Module.
5. Set the slide switch on the SG Control Module to
the “Lincoln” position.
Be sure this switch is set to the “Lincoln” (contact clo-
sure) position before attempting to operate the SG
Control Module. Incorrect switch position could result
in damage to the SG Control Module and/or the
Classic III or Classic IIID.
6. Place the IDLER switch on the Classic III or Classic
IIID in the “HIGH” position.
Any increase of the high idle engine RPM by changing
the governor setting or overriding the throttle linkage
will cause an increase in the AC auxiliary voltage. If
this voltage goes over 140 volts, wire feeder control
circuits may be damaged. The engine governor set-
ting is preset at the factory — do not adjust above
RPM specifications listed in this manual.
7. Adjust wire feed speed at the SG Control Module.
NOTE: For remote control, a K775 remote control is
required.
When the welder is in local control, the electrode is
always “HOT.”
