Optimize your welding operations with the Sumig 0900.1754 Contact Tip, specifically engineered for the Sumig 477 series MIG guns. These tips are manufactured from Copper Chromium Zirconium (CuCrZr), a high-performance alloy known for its exceptional hardness and thermal stability. Unlike standard E-Cu copper tips, CuCrZr tips maintain their structural integrity at much higher temperatures, making them the superior choice for high-amperage applications, pulsed MIG welding, and automated environments where downtime must be minimized.
The 0.045-inch (1.2mm) bore is precision-drilled to ensure consistent wire feeding and maximum electrical transfer to the welding wire. This results in a stable arc, reduced micro-arcing inside the tip, and less spatter generation. In industrial settings where duty cycles are high, the resistance of CuCrZr to annealing (softening) prevents the bore from becoming oval-shaped ("keyholing") prematurely. This pack contains 10 contact tips, ensuring you have the necessary consumables on hand to maintain continuous production.
CuCrZr alloys are the industry standard for heavy-duty welding. By adding chromium and zirconium to the copper matrix, the material's softening temperature is significantly raised without drastically compromising electrical conductivity. This balance is critical for maintaining the precise contact point required for high-quality welds over long shifts.
