CAUTION
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.

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-
