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.
