ANALOG MILLER CONTROL CABLE
ADAPTER K2335-1
This Lincoln Electric wire feeder may be mounted to a limit-
ed number of Miller Electric power sources. The Miller
power source must have the amphenol pin definition shown
in the table below for proper operation of the wire feeder.
Operation of Lincoln wire feeders on Miller power sources
may result in lack of high speeds or reduce pull force on
high wire feed speeds. Maximum wire feed speed for the
LF-72 operating on a Miller power source is approximately
720ipm. Be sure the Miller power source provides 24 VAC
to the wire feeder and has overcurrent protection of no more
than 15 amps. The power source must not exceed 113VDC
peak.
