CONNECTION OF THE LN-7 TO THE
CLASSIC II USING K867 UNIVERSAL
ADAPTER (SEE FIGURE C.1.)
1. Shut the welder off.
2. Connect the electrode cable from the LN-7 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.1 shows the electrode connected
for positive polarity. To change polarity,
shut the welder off and reverse the elec-
trode and work cables at the Classic II
output terminals.
3. Connect the K867 Universal Adapter to the K291 or
K404 input cable and the 14 pin amphenol of the
Classic II as indicated in Figure C.1. Make the
proper connections for local or remote control
according to Figure C.1.
4. Connect the K291 or K404 input cable to the LN-7.
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-7.
NOTE: For remote control, a K775 remote control is
required. See Figure C.1.
When the welder is in local control, the electrode is
always “HOT.”
