218713 - Miller 20-24 AWG Solder Cup Pin for MS/Amp Connectors (5-Pack)

Precision Connectivity for Industrial Welding Equipment

The Miller 218713 Connector Pin is a critical component designed for the maintenance and repair of circular MS (Military Standard) and Amphenol-style connectors found on Miller welding equipment. These connectors are the lifeline of modern welding systems, carrying vital control signals between power sources, wire feeders, and remote control devices. When a pin becomes damaged, corroded, or loose, it can lead to intermittent faults, loss of arc control, or complete system failure. This genuine Miller OEM part ensures that your equipment operates at the manufacturer's original specifications, maintaining the reliability required for industrial applications.

Engineered specifically for 20-24 gauge wire, this pin features a solder cup termination style. In the realm of electrical connectivity, the solder cup offers distinct advantages for field repairs and custom cable fabrication. Unlike crimp connections which require specialized, often expensive tooling to achieve a gas-tight seal, a solder cup allows for a metallurgical bond between the wire and the contact. This results in a connection with exceptionally low electrical resistance and high mechanical strength, capable of withstanding the vibration and thermal cycling common in welding environments. The cup is sized precisely to accept the stripped conductor of 20-24 AWG wire, facilitating a clean and manageable soldering process.

The "push-in" design of the Miller 218713 simplifies the assembly of the connector. Once the wire is soldered to the pin, the contact is inserted into the rear of the connector insert (the dielectric block) until it locks into place. This modularity allows technicians to replace individual damaged pins without needing to replace the entire expensive connector assembly. Whether you are rebuilding a 14-pin Amphenol plug for a foot pedal or repairing the internal wiring harness of a heavy-duty power source, these pins provide the precise fit and finish necessary for a professional repair. This package contains five pins, providing ample spares for multi-pin connector maintenance.

Using genuine Miller parts like the 218713 guarantees compatibility with the specific tolerances of the connector housings used on Miller machines. Generic pins may suffer from slight dimensional variances that can lead to poor mating force, fretting corrosion, or difficulty in insertion and extraction. By choosing the OEM specification, maintenance personnel ensure the longevity of the repair and the safety of the equipment operator.
