61N41 - ESAB 3/32" Heavy Duty Contact Tube for ST/MT Series Guns (5-Pack)

High-Performance 3/32" Contact Tips for ESAB Systems

Maximize the performance of your ESAB MIG welding system with the 61N41 Contact Tube, specifically engineered for 3/32-inch (2.4mm) welding wire. In heavy industrial welding, the contact tip is the final transfer point for welding current, making its quality and condition paramount to arc stability. The 61N41 is manufactured from high-grade copper alloy, optimized to provide excellent electrical conductivity while resisting the thermal deformation that can occur at high amperages. This balance of properties ensures a stable arc, reduced spatter, and consistent weld bead profiles.

Designed for the rigors of heavy fabrication, this contact tube fits the classic ESAB ST-12 and ST-23 guns, as well as the robust MT-200, MT-400, and MT-500 series. The "H" designation often associated with this series implies a heavy-duty wall thickness or alloy composition intended to resist the "keyholing" effect—where the wire wears an oval shape into the tip exit—common with large diameter, stiff wires. By maintaining a concentric bore for longer periods, the 61N41 ensures the wire is directed precisely into the weld joint, improving targeting and penetration.

For welders utilizing flux-cored arc welding (FCAW) or high-deposition metal-cored welding, the 3/32" size is a standard for high productivity. Using inferior or mismatched contact tips in these applications can lead to overheating and fusion of the wire to the tip. ESAB's OEM specifications for the 61N41 guarantee the correct tolerance between the wire and the tube wall, allowing for smooth feeding even when the gun cable is bent or the duty cycle is pushed to the limit. This pack of 5 ensures you have replacements on hand to maintain continuous operation.
