403-1-45 - CK 403-1-45 Heavy Duty Contact Tip for Tregaskiss MIG Guns (.045 in, 25-Pack)

Heavy Duty Performance for Tregaskiss Systems

The CK 403-1-45 Contact Tip is a premium-quality consumable designed to meet the demands of industrial MIG welding. Engineered as a direct replacement for the standard Tregaskiss 403-1-45, this heavy-duty tip is specifically sized for .045 inch (1.2 mm) welding wire. It is compatible with widely used Tregaskiss 300 amp and 400 amp MIG guns, making it a versatile addition to any welding inventory. The tip is designed to thread seamlessly into 404-3 and 404-1 gas diffusers, ensuring a secure electrical connection and optimal gas coverage.

In high-production environments, the durability of your contact tip directly impacts efficiency. This heavy-duty variant features a robust copper construction that offers superior thermal conductivity and resistance to heat buildup. This results in a longer lifespan compared to standard tips, reducing the frequency of tip changes and minimizing production interruptions. The bore is precision-drilled to tight tolerances, promoting smooth wire feeding and stable arc transfer, which is critical for achieving high-quality welds.

Each package contains 25 contact tips, providing a cost-effective solution for busy fabrication shops. Every tip is clearly marked with the part number, simplifying identification and inventory management. Whether you are welding structural steel, heavy equipment, or general fabrication projects, the CK 403-1-45 delivers the reliability and performance professional welders expect from their equipment.
