KP36CT-B25 - Lincoln Electric KP36CT-B25 Magnum MIG Gun Insulator (25 Pack)

Reliable Insulation for Industrial MIG Welding

The Lincoln Electric KP36CT-B25 Coarse Thread Insulator Assembly is a critical component for maintaining the performance and safety of your Lincoln Magnum series MIG guns. Designed specifically for the Magnum 300 and 400 amperage range, this insulator serves the vital function of electrically isolating the gas nozzle from the live contact tip and diffuser. Without a functioning insulator, welders risk electrical shorts, nozzle arc-outs, and inconsistent shielding gas coverage, all of which can compromise weld quality and damage expensive torch components.

This specific model features a "Coarse Thread" design, denoted by the "CT" in the part number. In heavy-duty industrial applications, fine threads can often become clogged with micro-spatter or seize due to the extreme thermal expansion and contraction cycles inherent in welding. The coarse thread profile of the KP36CT is engineered to resist this seizing, allowing for easier removal and replacement during routine maintenance. This design choice significantly reduces downtime on the shop floor, as operators struggle less with stuck components when changing nozzles or tips.

Supplied in a convenient pack of 25, the KP36CT-B25 is intended for high-volume fabrication environments where consumable inventory management is key to operational efficiency. By stocking the 25-pack, procurement managers ensure that welding stations remain operational without interruption. As a genuine Lincoln Electric OEM part, these insulators are manufactured to precise tolerances, ensuring a tight seal and proper alignment within the gun assembly. This guarantees that shielding gas is directed precisely where it is needed, protecting the weld pool from atmospheric contamination.

Whether you are managing a large manufacturing line or a specialized repair shop, using genuine Lincoln consumables like the KP36CT insulator ensures that your equipment operates at the manufacturer's rated specifications. Invest in the longevity of your MIG guns and the quality of your output with this essential replacement part.
