9SS18653 - Lincoln Electric S18653 Connector Pin for Magnum MIG Guns

Restore Your Magnum MIG Gun with the Lincoln S18653 Pin

The Lincoln Electric S18653 Connector Pin is an essential replacement part for welders using Lincoln Magnum MIG guns and compatible wire feeders. This specific pin is used within the control cable connector—often referred to as the trigger plug—to establish the electrical link between the gun and the power source. When you pull the trigger on your MIG gun, this pin carries the signal that tells the machine to start feeding wire and energize the contact tip. A compromised pin can result in a "dead trigger" situation, where the machine fails to respond, or intermittent operation that ruins weld quality.

Constructed from high-conductivity metal alloy, the S18653 pin offers excellent electrical performance and resistance to oxidation. It is designed to withstand the mechanical stress of repeated connecting and disconnecting, which is common in shops where guns are frequently swapped or moved between machines. The pin's geometry is precisely engineered to mate correctly with the female socket on the wire feeder, ensuring a low-resistance connection that maintains signal integrity. Using genuine Lincoln parts like the S18653 protects your equipment from the potential damage caused by poor electrical contact, such as heat buildup in the connector.

This pin is compatible with a wide range of Lincoln Magnum series guns and is a standard component in many Lincoln wire feeder control plugs (often associated with the #4 connection style or similar amphenol configurations). It is an ideal solution for technicians and welders performing their own equipment maintenance. Instead of replacing an entire expensive control cable assembly, a skilled repair using the S18653 pin can restore full functionality for a fraction of the cost.

Welders Supply Company provides this genuine Lincoln Electric component to help you maintain the reliability of your welding fleet. Whether you are troubleshooting a connection issue or refurbishing an older MIG gun, the S18653 Connector Pin is the correct part for the job. Don't let a small electrical fault stop your production; rely on genuine Lincoln replacement parts for durable and consistent performance.
