Q403-1-564 - ESAB Oxo 5/64" Heavy Duty Contact Tip (Pack of 25)

Precision Engineered for Industrial Performance

The ESAB Oxo Q403-1-564 Contact Tip is a premium consumable designed to meet the rigorous demands of heavy industrial welding. Engineered specifically for Oxo style MIG guns, these contact tips are manufactured from high-grade copper alloy, ensuring optimal electrical conductivity and thermal transfer. The 5/64-inch (approx. 2.0mm) bore is precision-drilled and honed to tight tolerances, providing a consistent electrical contact point with the welding wire. This is critical for maintaining a stable arc, particularly in high-deposition applications where current transfer efficiency directly impacts weld quality.

In heavy-duty welding environments, thermal buildup is the primary enemy of contact tip longevity. The "Heavy Duty" designation of the Q403-1-564 indicates a robust wall thickness and substantial mass, allowing the tip to absorb and dissipate heat more effectively than standard light-duty tips. This thermal management capability reduces the risk of the tip softening, which can lead to bore deformation (keyholing) and premature failure. By maintaining its structural integrity under high heat, this contact tip ensures reliable wire feeding and reduces the frequency of burn-backs, which can cause costly downtime.

This product is supplied in a convenient pack of 25, catering to high-volume fabrication shops that require a steady supply of consumables. The tips are compatible with a range of Oxo MIG guns often found in structural steel, shipbuilding, and heavy equipment manufacturing. Whether running solid wire or flux-cored wire, the ESAB Oxo 5/64" tip delivers the performance consistency required for code-quality welds. The smooth internal finish minimizes friction, further aiding in the prevention of wire shaving and feeding issues.
