OVERVIEW

Technical Overview of the Tweco 1640-1113 Flexible Conductor Tube

The Tweco 1640-1113 is a specialized conductor tube designed for use with Tweco #3 and #4 series MIG guns. As a critical component of the MIG welding torch assembly, the conductor tube, often referred to as a gooseneck, serves as the conduit for both the welding current and the shielding gas, directing them from the gun handle to the contact tip and nozzle. This specific model features a flexible body design, distinguishing it from standard rigid tubes. The flexibility allows for minor adjustments and positioning, which is essential when operating in complex fixtures or restricted spaces where a standard fixed-angle neck would be impractical.

Engineered with an 80-degree bend, this conductor tube provides a steep angle of attack, suitable for specific joint configurations that require the torch to be positioned almost perpendicular to the handle axis or for reaching over obstacles. The tube is constructed from high-conductivity copper alloys to ensure efficient power transfer with minimal resistance, thereby reducing heat buildup during prolonged welding operations. It is rated to handle the amperage capacities associated with Tweco #3 (300 Amps) and #4 (400 Amps) guns, making it a versatile component for medium to heavy-duty industrial fabrication.

Installation of the 1640-1113 is straightforward, utilizing the standard connection mechanisms found on Tweco gun handles. The outer jacket is designed to resist spatter adhesion and abrasion, prolonging the service life of the component in harsh welding environments. By maintaining the integrity of the gas flow and electrical path, this genuine Tweco part ensures consistent arc stability and weld quality.

FAQ

This conductor tube is designed to fit Tweco #3 (300 Amp) and Tweco #4 (400 Amp) series MIG guns.

It is a flexible conductor tube, allowing for some adjustment to reach difficult areas.

This specific model features an 80-degree bend angle.

No, the conductor tube is sold separately. The gun liner typically runs through the handle and up to the diffuser, or a jump liner is used depending on the specific gun setup.

Installation generally involves loosening the set screw or retention nut on the gun handle, removing the old tube, inserting the new one, and tightening the fastener to secure it.

Yes, this is a genuine Tweco OEM replacement part.

It is rated to match the capacity of the guns it fits, typically supporting up to 400 Amps when used with a Tweco #4 gun.
