16401105 - Tweco 64J-45 Conductor Tube for Spray Master 450 - 45 Degree Jacketed

Tweco 1640-1105 (64J-45) Replacement Conductor Tube

Keep your welding equipment running at peak efficiency with the Tweco 1640-1105, also known as the 64J-45 Conductor Tube. This is the standard replacement gooseneck for the Tweco Spray Master 450 (MS450) MIG gun, a workhorse in the welding industry known for its reliability and ease of maintenance. The conductor tube is a vital component of the MIG gun assembly, responsible for conducting the welding current to the contact tip and directing the shielding gas flow. A compromised tube can lead to overheating, gas leaks, and feeding issues, making timely replacement crucial for quality assurance.

The 64J-45 features a robust 45-degree bend, which is the industry standard for general fabrication, providing a balance between reach and ergonomic comfort. What sets the "J" series apart is its jacketed insulation. Unlike bare metal tubes, this model is wrapped in a durable insulating material that safeguards against inadvertent electrical contact with the base metal. This feature is critical in tight spaces or complex fixtures where the gun neck might brush against conductive surfaces. The heavy-wall copper construction ensures excellent thermal conductivity, helping to dissipate heat effectively during long welds at high amperages.

Installation is straightforward, adhering to Tweco's user-friendly design philosophy. The tube seats securely into the gun handle, ensuring a leak-free gas connection and solid electrical contact. By maintaining your Spray Master 450 with genuine Tweco parts like the 1640-1105, you extend the life of your welding gun and ensure consistent weld quality. This part is essential for any shop using MS450 guns, ensuring that downtime is minimized and production keeps moving.
