403-1-35 - CK Heavy Duty .035 Contact Tip for Tregaskiss MIG Guns (25-Pack)

Precision Engineered for High-Amperage MIG Welding

The CK 403-1-35 Contact Tip is a premium-grade consumable designed to meet the rigorous demands of industrial MIG welding. Engineered as a direct replacement for Tregaskiss style systems, this heavy-duty contact tip is specifically calibrated for use with .035-inch (0.9 mm) welding wire. It is compatible with 300A and 400A Tregaskiss MIG guns, making it a versatile component for fabrication shops utilizing these common torch platforms. The tip is designed to seat perfectly into 404-3 and 404-1 gas diffusers, ensuring a secure electrical connection and optimal gas coverage.

Constructed from high-quality copper alloy, the 403-1-35 features a heavy-duty design characterized by a thicker wall compared to standard light-duty tips. This increased mass allows for superior thermal conductivity and heat dissipation, which is critical when welding at higher amperages or duty cycles. By effectively managing heat buildup, the tip maintains its structural integrity longer, resisting the keyholing and bore erosion that often lead to arc instability and premature failure. The precision-drilled bore ensures consistent wire feeding and electrical contact, minimizing micro-arcing inside the tip.

Identification and inventory management are simplified as each contact tip is clearly marked with its part number. This reduces the risk of installing the incorrect size during changeovers, which can cause wire jamming or poor weld quality. Supplied in a package of 25, these tips offer excellent value for high-volume operations, ensuring that maintenance teams have the necessary stock to keep production lines moving without interruption. Whether used in robotic automation or manual fabrication, the CK 403-1-35 delivers the reliability and performance required for professional welding environments.

Technical specifications include a standard thread pitch compatible with the specified Tregaskiss diffusers and a length optimized for proper stick-out in standard nozzle configurations. The heavy-duty classification indicates its suitability for industrial environments where arc time is high and equipment durability is paramount.
