633611 - ESAB 7/64" Heavy Duty Contact Tip (Pack of 5)

High-Performance Contact Tips for Heavy Fabrication

The ESAB 633611 Contact Tip S 7/64H-C is a premium welding consumable designed to meet the rigorous demands of heavy industrial fabrication. Engineered specifically for use with 7/64-inch (approx. 2.8mm) welding wire, this contact tip is an essential component for maintaining process stability in high-deposition welding environments. Whether utilizing Flux-Cored Arc Welding (FCAW) or heavy-duty MIG processes, the integrity of the electrical connection between the power source and the filler metal is paramount. This contact tip ensures that current transfer is efficient and consistent, reducing voltage drops and promoting a smooth, stable arc.

Manufactured from high-grade copper alloy, the 633611 tip offers superior thermal conductivity and electrical performance. The material composition is selected to withstand the intense heat generated during prolonged welding cycles, resisting softening and deformation that can lead to premature failure. The internal bore is precision-machined to tight tolerances, ensuring a proper fit for 7/64" wire. This precise fit minimizes micro-arcing inside the tip—a common cause of burn-back and erratic feeding—while still allowing for the smooth passage of the wire. This balance is critical for automated or semi-automated applications where downtime must be minimized.

Supplied in a convenient pack of five, these contact tips allow procurement managers and shop foremen to maintain adequate stock levels for continuous operation. Regular replacement of contact tips is a standard maintenance procedure that directly impacts weld quality. By choosing genuine ESAB consumables, operators can rely on consistent geometry and material quality, ensuring that every tip performs as expected right out of the package. This product is compatible with specific ESAB heavy-duty welding guns, making it a reliable choice for workshops standardized on ESAB equipment.
