0153503001 - ESAB M4x30 Contact Tip for 0.6mm Wire (10 Pack)

Precision Engineering for Consistent Arc Transfer

The ESAB Contact Tip M4x30 is a critical consumable component designed to facilitate the precise transfer of welding current to the electrode wire. Engineered with a specific M4 thread pitch and a total length of 30mm, this contact tip is manufactured to strict tolerances to ensure concentricity and optimal electrical contact. It is specifically bored for 0.6mm (0.023 inch) welding wire, a diameter commonly utilized in light-gauge fabrication and automotive bodywork. The correct bore-to-wire tolerance is essential in preventing micro-arcing within the tip, which can lead to premature failure, burn-back, and unstable arc characteristics.

Constructed from high-grade copper alloy, these tips offer superior thermal conductivity, effectively dissipating the intense heat generated during the welding process. This thermal management helps maintain the structural integrity of the tip over prolonged use, reducing the frequency of replacements. The M4 thread ensures a mechanical interface that remains secure under thermal cycling, preventing the loosening that can cause high-resistance heating at the diffuser connection. For industrial MRO procurement, ensuring the use of genuine OEM consumables like this ESAB tip guarantees compatibility with specific ESAB torch models and maintains the manufacturer's performance specifications.

This product is supplied as a package of 10 units, providing a cost-effective solution for inventory management. Regular replacement of contact tips is a standard maintenance procedure in MIG welding; as the bore wears into an oval shape, the electrical contact point shifts, causing erratic wire feeding and arc wandering. By maintaining a stock of these precision tips, operators can ensure consistent weld quality and reduce troubleshooting time related to wire feed issues. These tips are compatible with a range of ESAB MIG guns that utilize the M4 consumable system.
