0413510002 - ESAB A2/A6 Contact Tube D20 190mm for 2.5mm Wire

Heavy-Duty Contact Tube for Automated Welding

The ESAB 0413510002 Contact Tube is a critical component designed for high-performance automated welding systems, specifically the ESAB A2 and A6 welding heads. In industrial manufacturing and heavy fabrication, the reliability of the current transfer mechanism is paramount to maintaining weld quality and production speed. This contact tube is engineered to meet those rigorous demands, providing a stable electrical connection between the power source and the welding wire.

Constructed from a high-grade copper alloy, this tube offers superior thermal and electrical conductivity. The 190mm length is specifically dimensioned to fit the torch geometry of ESAB's submerged arc welding (SAW) equipment, allowing for appropriate reach and positioning within the flux bed or joint groove. With an outer diameter (OD) of 20mm, the tube is robust enough to withstand the high heat and mechanical stresses associated with continuous, high-amperage welding cycles.

This specific SKU is precision-bored for 2.5mm welding wire. Using the correct bore size is essential for preventing micro-arcing inside the tip and ensuring smooth wire feeding. By maintaining tight tolerances, ESAB ensures that the arc remains stable and centered, which is crucial for the uniform bead profile required in structural steel, pipe, and pressure vessel fabrication. Josef Gas provides this OEM part to ensure your automated systems operate at peak efficiency with minimal downtime for maintenance.
