Industrial-grade rear termination power pin and control interface designed to connect Tweco Classic and Spray Master series MIG guns to Lincoln Electric wire feeders. This assembly functions as a heavy-duty electrical conduit and multi-channel signal interface, facilitating current flow and telemetry synchronization between the gun and the wire feeder.
Features
5-Pin Amphenol Control Plug: Matches standard Lincoln Electric control receptacles to sync trigger switching and wire feed commands without field splices.
Copper-to-Copper Direct Contact: Machined copper body seats directly against the host power source block to act as an external heat sink and prevent thermal runaway.
Integrated Shielding Gas Porting: Machined internal gas passageways transfer gas from the feeder through the gun cable without external hoses.
Dual O-Ring Groove Sealing: Prevents ambient air ingress and shielding gas loss under high pressure.
Heavy-Duty Strain Relief: Steel spring support disperses bending forces at the cable entrance to prevent wire kinking or bird-nesting.
Multi-Channel Signal Interface: Supports dual-schedule telemetry loops and trigger synchronization.
