OVERVIEW

Restore Your Torch with the Tweco 9911-2001 Head Assembly

Keep your MIG gun running like new with the Tweco 9911-2001 Head Assembly. In the world of welding, the condition of your torch directly impacts the quality of your work. The head assembly, or conductor tube, is the final pathway for both the welding wire and the shielding gas before they reach the arc. If your current conductor tube is bent, stripped, or clogged with spatter, it can cause frustrating feeding issues and inconsistent welds. This authentic Tweco replacement part is the solution to getting your equipment back in fighting shape.

Designed for durability and performance, the 9911-2001 is built tough to handle the rigors of daily welding. It features robust threads that hold your gas diffuser and nozzle securely in place, preventing the loose connections that lead to resistive heating and premature failure. The angle of the tube is designed to provide comfortable ergonomics, allowing you to access joints easily while maintaining the proper torch angle. Don't struggle with a damaged gun that fights you every inch of the bead; a fresh head assembly is a cost-effective repair that makes a noticeable difference in arc stability.

Why Choose Genuine Tweco Parts?

When you buy the Tweco 9911-2001, you are investing in the reliability of the industry leader in MIG gun technology. Generic replacements often cut corners on material quality, leading to faster overheating and poor current transfer. This OEM part guarantees that the copper content and wall thickness meet the original specifications of your gun, ensuring it can handle the amperage it was rated for. It is the perfect fix for welders who take pride in their tools and need equipment that performs consistently, weld after weld.

Quick and Easy Replacement

Swapping out a damaged head assembly is one of the easiest repairs you can perform on a MIG gun. Simply disconnect the old tube from the handle/cable connection and thread on the new 9911-2001. This simple maintenance step can solve a host of mysterious welding problems, from sputtering arcs to gas turbulence. Keep a spare in your toolbox to ensure that a dropped torch or stripped thread doesn't stop production. At Welders Supply, we provide the high-quality parts you need to keep your sparks flying and your projects on schedule.
