CONNECTION OF THE K488 SG
CONTROL MODULE AND K487 MAGNUM
SPOOL GUN TO THE RANGER 300
(DLX ONLY) (SEE FIGURE C.6.)
1. Shut the welder off.
2. Connect the electrode cable from the SG Control
Module to the ELECTRODE terminal of the welder.
Connect the work cable to the WORK 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. Use the Polarity switch on the Ranger
300 DLX to select the desired electrode polarity.
3. Connect the K691-10 Input Cable as shown in
Figure C.6.
4. Set the slide switch on the SG Control Module to
the “Lincoln” position.
Be sure the 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
Ranger 300 DLX.
5. Place the IDLER switch 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.
6. Set the LOCAL/REMOTE switch to “REMOTE” if a
K857 remote control is used. Set the switch to
“LOCAL” if no remote control is used.
7. Set the OUTPUT RANGE switch to “WIRE WELD-
ING CV.”
8. Set the WELDING TERMINALS switch to “WELD-
ING TERMINALS REMOTELY CONTROLLED.”
9. Adjust wire feed speed at the SG Control Module.
NOTE: For remote control, a K857 remote control is
required. Connect it to the 6-pin amphenol.
