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 “-” terminal of the welder.
NOTE: Welding cable must be sized for current and
duty cycle of application.
NOTE: Figure C.2 shows the electrode connected for
positive polarity. To change polarity, shut the welder
off and reverse the electrode and work cables at the
Commander 500 output terminals.

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 cir-
cuits may be damaged. The engine governor setting is
preset at the factory—do not adjust above RPM speci-
fications listed in this manual.
