17155 - ESAB MT Series Contact Tube 0.052" Heavy Duty (5-Pack)

ESAB MT Series Contact Tube for 0.052" Wire

The ESAB 17155 Contact Tube is a specialized consumable designed for use with MT series MIG welding guns. Engineered to accommodate 0.052-inch (1.3mm) welding wire, this component plays a critical role in the transfer of welding current to the electrode. The "H-C" designation typically indicates a heavy-duty specification, suggesting these tubes are manufactured from high-grade copper alloys capable of withstanding the thermal and mechanical stresses of industrial welding environments.

Proper contact tube selection is vital for maintaining process stability. This specific model features a precision-drilled bore that provides the necessary clearance for 0.052" wire while maintaining sufficient contact area for efficient conductivity. The tubes are supplied in a pack of 5, allowing for routine maintenance schedules and quick replacement on the production line. They are direct replacements for worn consumables in compatible ESAB/L-Tec MT style torches.

Regular inspection and replacement of contact tubes are recommended to prevent issues such as burnback, erratic arc starts, and poor wire feeding. These genuine ESAB parts ensure dimensional accuracy and material quality consistent with the original equipment specifications of the torch system.
