998071 - ESAB Contact Tip for W-Series MIG Guns

Precision Contact Tip for W-Series MIG Torches

The ESAB 998071 Contact Tip is a critical consumable component engineered for the W250, W300, and W400 series of MIG welding guns. Manufactured from high-grade copper alloy, this contact tip is designed to facilitate efficient electrical transfer from the welding gun to the wire electrode. The material composition is selected to balance thermal conductivity with wear resistance, ensuring the tip maintains its structural integrity even under the high heat conditions typical of industrial welding operations.

Dimensional accuracy is paramount in contact tip performance. This unit features a precision-drilled bore that matches specific wire diameters, minimizing play while preventing binding. This tight tolerance ensures the welding current is transferred consistently to the wire, which is vital for maintaining a stable arc and achieving uniform penetration. The exterior threading is machined to exact specifications for a secure fit into the gas diffuser or tip holder, preventing gas leaks and ensuring optimal shielding gas coverage.

Regular replacement of contact tips is a standard maintenance procedure in MIG welding to prevent issues such as keyholing, burnback, and erratic arc behavior. The ESAB 998071 is designed for quick changeovers, allowing operators to minimize downtime. Whether used in manual fabrication or automated setups involving W-series torches, this contact tip delivers the reliability required for high-quality weld deposits.
