This Lincoln Electric wire feeder may be mounted to a
limited number of Miller Electric power sources. The
Miller power source must have the circular connector
pin definition shown in the table below for proper oper-
ation of the wire feeder. 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.
Operation of Lincoln wire feeders on Miller power
sources may result in lack of high wire feed speeds or
reduced pull force at high wire feed speeds.
