0155197001 - ESAB Contact Tube D20 for 4.0mm Wire - A2/A6 Automation

Precision Contact Tube for ESAB Automation Systems

The ESAB Contact Tube D20 (Part Number 0155197001) is a critical component designed for the rigorous demands of automated welding. Engineered specifically for use with ESAB A2 and A6 automatic welding heads, this contact tube ensures precise wire guidance and optimal electrical conductivity. It is manufactured to handle the high duty cycles and amperages typical of Submerged Arc Welding (SAW) and heavy-duty MIG/MAG automation.

This specific model features a D20 (20mm) outer diameter and is bored to accommodate 4.0mm welding wire. The substantial copper alloy construction provides excellent heat dissipation and wear resistance, reducing downtime associated with frequent tip changes. In automated setups where consistency is paramount, using genuine ESAB contact tubes helps maintain a stable arc and uniform bead profile by ensuring the wire is energized correctly as it exits the torch assembly.

Technical Reliability

Automated welding systems like the A2 and A6 require components that fit perfectly to prevent arcing within the head or wire feed issues. The D20 interface of this tube fits securely into the standard contact jaws of the A2/A6 system, providing a low-resistance electrical path. This is essential for maintaining voltage stability and achieving high-quality weld deposits in structural steel, pipe, and vessel fabrication.
