9ST9967-10 - Lincoln Electric Wire Feeder Tension Arm Replacement T9967-10

Restore Precision to Your Wire Feeding System

The Lincoln Electric Tension Arm is a vital replacement component designed to maintain the integrity of your MIG welder's wire drive assembly. In any wire feeding system, the tension arm plays a critical role: it holds the idle roll firmly against the drive roll, sandwiching the welding wire with the precise amount of pressure needed to push it through the liner and out the contact tip. Over time, mechanical stress, heat, and constant vibration can cause these arms to wear, bend, or crack, leading to erratic feeding and frustration for the operator.

When a tension arm fails or loses its rigidity, the result is often wire slippage. You might notice your wire speed fluctuating unexpectedly, or the wire stopping completely even though the drive rolls are spinning. This leads to poor weld quality, increased spatter, and potential burn-back issues that can damage your gun liner. By replacing a compromised arm with this high-quality Lincoln Electric part, you ensure that your machine delivers the consistent performance required for professional fabrication.

This specific arm is engineered to meet Lincoln's exact specifications, ensuring a perfect fit within the tension assembly of compatible wire feeders. It is constructed from durable materials capable of withstanding the high-pressure environment of an industrial wire drive. Whether you are repairing an older shop machine or performing preventative maintenance on a fleet of field welders, installing a new tension arm is a cost-effective way to extend the life of your equipment and maintain productivity.

Installation is generally straightforward, requiring minimal tools. It is designed to integrate seamlessly with the existing spring and adjustment knob mechanisms of your Lincoln feeder. Don't let a small mechanical part compromise your welding projects; ensure your wire delivery is smooth and reliable with this genuine replacement arm.
