CONNECTION OF THE K488 SG CONTROL
MODULE AND K487 MAGNUM SPOOL GUN
TO THE CLASSIC II (SEE FIGURE C.5.)

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.5 shows the electrode connect-

ed for positive polarity. To change polari-
ty, shut the welder off and reverse the
electrode and work cables at the Classic II
output terminals.

3. Connect the K867 Universal adapter to the K492

input cable as shown in Figure C.5. Connect the
other end of the adapter to the 14 pin amphenol on
the Classic II.

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 II.

6. Place the IDLER switch on the Classic II 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.”
