11501210 - Tweco 15H-332 Heavy Duty Contact Tip 3/32" for Classic #5 Gun (Pack of 25)

Tweco 15H-332 Contact Tip for Heavy Industrial Applications

The Tweco 15H-332 Contact Tip (SKU: 1150-1210) is a premium OEM consumable designed specifically for the legendary Tweco Classic #5 MIG gun. Engineered to handle the rigorous demands of heavy fabrication, this contact tip is sized for 3/32-inch (2.4mm) welding wire, a diameter typically reserved for high-deposition structural and manufacturing applications. As part of the 15H series, these tips feature a heavy-duty construction with increased wall thickness compared to standard duty tips, allowing them to absorb and dissipate the intense heat generated during high-amperage welding processes.

Precision manufacturing is at the core of the Tweco 15H-332. The internal bore is machined to exacting tolerances to ensure optimal electrical contact with the wire while minimizing friction that could lead to feeding issues. This precise fit is critical for maintaining a stable arc and preventing micro-arcing inside the tip, which is a common cause of premature failure. The tip utilizes a standard threaded connection that integrates seamlessly with the gas diffusers found on Classic #5 guns, ensuring a secure mechanical and electrical bond.

Supplied in a standard industrial package of 25 pieces, these contact tips are intended for high-volume welding environments where consistency and reliability are paramount. By using genuine Tweco OEM parts, operators ensure that their equipment performs to factory specifications. The copper alloy material is selected for its balance of hardness and electrical conductivity, providing a long service life even under the stress of continuous duty cycles. Whether welding mild steel, flux-cored wires, or other alloys compatible with 3/32" diameter feeds, the 15H-332 delivers the performance required for professional results.
