9SS29830-5 - Lincoln Electric S29830-5 Power Pin Assembly for Magnum MIG Guns

Genuine Lincoln Electric S29830-5 Power Pin Assembly

The Lincoln Electric S29830-5 is a critical replacement component designed for the backend of Magnum series MIG guns. As an Original Equipment Manufacturer (OEM) part, it is engineered to the exact specifications required for seamless integration with Lincoln wire feeders and power sources. This assembly serves as the primary interface between the welding gun cable and the machine, conducting both the high-amperage welding current and the shielding gas.

Constructed from high-grade brass alloy, the S29830-5 offers superior electrical conductivity, minimizing resistance and heat buildup at the connection point. This is essential for maintaining a stable arc and preventing premature wear of the feeder block. The precision machining ensures that the gas ports align perfectly with the feeder's gas output, while the included O-rings provide a positive seal to prevent atmospheric contamination of the weld pool. This power pin is specifically compatible with Lincoln Magnum 200, 300, and 400 amperage gun models.

Industrial maintenance professionals understand that the integrity of the gun-to-machine connection is paramount for consistent welding parameters. A worn or damaged power pin can lead to erratic wire feeding, gas leakage, and voltage fluctuations. Replacing a compromised pin with this genuine Lincoln assembly restores the gun's performance to factory standards, ensuring reliability in demanding fabrication environments.
