996104 - ESAB 0.035" MIG Contact Tips (Pack of 5)

Precision Electrical Transfer for MIG Welding

The ESAB 996104 Contact Tube ST 035 is a critical consumable component designed to facilitate the transfer of welding current to the electrode wire with maximum efficiency. Engineered specifically for 0.035-inch (0.9mm) diameter welding wires, these contact tubes are manufactured from a high-grade copper alloy selected for its superior thermal and electrical conductivity properties. In the Gas Metal Arc Welding (GMAW) process, the contact tip is the final point of electrical contact before the arc; therefore, the dimensional accuracy and material quality of the tip are paramount to maintaining a stable arc and consistent weld bead profile.

These contact tubes feature a standard M6 thread, making them compatible with a wide range of ESAB MIG guns and torch assemblies. The internal bore is precision-drilled and finished to ensure a smooth path for the wire, minimizing friction that can lead to feeding issues or bird-nesting at the drive rolls. The tight tolerance of the bore ensures constant electrical contact with the wire as it passes through, reducing the risk of micro-arcing inside the tip which can cause premature wear and voltage fluctuations. Proper heat dissipation is managed through the mass and geometry of the tip, helping to resist the intense thermal environment of the welding arc.

Supplied in a pack of five, these contact tubes allow industrial operators to maintain a ready supply of consumables, ensuring minimal downtime during production. Regular replacement of contact tips is a standard maintenance procedure required to prevent issues such as keyholing (where the bore becomes oval-shaped) or burnback. By utilizing genuine ESAB consumables, fabricators ensure that their equipment operates within the manufacturer's specified parameters for duty cycle and performance.
