The ITW Miller PSA-2 Control (141604) is a 115 VAC to 24 VAC industrial wire feed control adapter. It is designed to interface constant-speed or push-pull wire feeders with power sources that lack a 14-pin connection, provide only 115 VAC, or require a contact closure for contactor control. The unit features a steel housing and includes a 10-foot interconnecting cord for routing contact closure and providing secondary current for MIG welding operations.
