16501302 - Tweco 65-6 EX Conductor Tube 60 Degree for Spray Master MIG Guns

Tweco 1650-1302 Conductor Tube Extension 65-6 EX

The Tweco 1650-1302 (Model 65-6 EX) is a premium replacement conductor tube designed specifically for the renowned Tweco Spray Master® series of MIG guns. Engineered to meet the rigorous demands of industrial welding, this conductor tube serves as the critical link between the MIG gun cable and the consumables, ensuring consistent current transfer and smooth wire delivery. It is directly compatible with Spray Master 350 (MS350) and Spray Master 450 (MS450) air-cooled MIG guns, making it an essential spare part for fabrication shops utilizing these heavy-duty tools.

This specific model features a 60-degree bend angle. The 60-degree geometry is often preferred for general-purpose fabrication as it provides a comfortable hand position for the welder while allowing sufficient access to fillet welds and joints in various positions. The tube is constructed from high-grade copper alloy, selected for its superior electrical conductivity and thermal properties. Efficient heat dissipation is crucial in high-amperage applications (up to 450 amps) to prevent overheating of the front-end consumables and to maintain the structural integrity of the gun during long weld cycles.

Installation of the 65-6 EX is straightforward, featuring precision-machined threads that ensure a secure, gas-tight connection to the gun handle. This prevents shielding gas leaks which can lead to porosity in the weld. The tube is also insulated to protect against inadvertent arcing if the neck contacts the workpiece. By replacing a worn, bent, or clogged conductor tube with this genuine Tweco part, operators can restore the original performance characteristics of their Spray Master MIG gun, ensuring stable arcs and reliable wire feeding.
