99202302 - Tweco 32 Insulator Spring (2-Pack)

Reliable Insulation for Tweco MIG Guns

The Tweco 9920-2302 Insulator Spring Packaged is a critical consumable component designed for professional MIG welding operations. Commonly referred to as the "Part No. 32" insulator, this item serves a dual purpose in the assembly of Tweco MIG guns. Primarily, it provides essential electrical insulation between the electrically live gas diffuser and the outer gas nozzle. This isolation is vital to prevent the nozzle from becoming electrically charged, which could lead to accidental arcing if the nozzle contacts the workpiece. Secondly, the 32 insulator acts as the friction-based retention mechanism for Tweco's slip-on style nozzles (Series 22, 23, and 24).

Manufactured from a robust high-temperature fiberglass and silicone composite, this insulator is engineered to withstand the intense heat and spatter generated during high-amperage welding. It is compatible with a wide range of industry-standard torches, including the classic Tweco No. 2, No. 3, and No. 4 air-cooled MIG guns, as well as the Spray Master series. This specific SKU (9920-2302) represents a retail-ready package containing two (2) insulators, making it an excellent choice for inventory management and quick field replacements.

Technical Specifications and Fitment

The Tweco 32 insulator fits securely over the gas diffuser (typically Part No. 52 or 52-23) and seats against the conductor tube. Its outer surface provides the necessary grip to hold adjustable slip-on nozzles in place, allowing the welder to adjust the nozzle recess or stick-out easily. Regular inspection of the insulator is recommended; if the material becomes charred, cracked, or loses its spring tension, it should be replaced immediately to maintain weld quality and safety.
