CONNECTION OF THE LN-25 TO THE
SA-250 WITH K623-1 WIRE FEED MODULE USING
K867 UNIVERSAL ADAPTER (SEE FIGURE C.3.)
1. Shut the welder off.
2. Connect the electrode cable from the LN-25 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.3 shows the electrode connected for
positive polarity. To change polarity, shut the welder
off and reverse the electrode and work cables at the
SA-250 output terminals. Reverse the LN-25 polarity
switch.
3. Connect the K867 Universal adapter to the K433
cable and the 14 pin amphenol of the SA-250 as
indicated in Figure C.3. Mount the K433 to the
welder according to instructions included with the
K433 kit.
4. Connect the K432-L cable to the LN-25 equipped
with the K431-1 remote output control kit.
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. Adjust wire feed speed and voltage at the LN-25.
