20502147 - Tweco Cable Support Spring 2050-2147

Protect Your Equipment with the Tweco Cable Support Spring

Every welder knows that a smooth wire feed is the key to a consistent, high-quality weld. Often, feeding issues aren't caused by the machine or the wire itself, but by the condition of the MIG gun cable. The Tweco Strain Relief Spring (Part No. 2050-2147) is your first line of defense against cable damage. Designed to sit at the high-stress points of your welding gun—typically where the cable enters the handle—this heavy-duty spring ensures that your cable never bends too sharply. A sharp bend can crush the gas hose and pinch the liner, leading to porosity in your welds and frustrating wire chatter.

Why Strain Relief Matters
Welding cables are heavy and expensive. Without proper support, the weight of the cable hanging from the gun can cause the copper strands inside to fatigue and break over time, leading to hot spots and power loss. This Tweco spring distributes that weight and limits the angle of the bend, significantly reducing wear and tear. It acts as an exoskeleton for the most vulnerable part of your setup, ensuring that gas flows freely and wire slides smoothly through the liner, no matter what position you are welding in.

Built for the Shop
Made from industrial-grade spring steel, this support is built to handle the rough conditions of a fabrication shop. It resists deformation and maintains its protective properties shift after shift. Whether you are repairing an existing gun or refurbishing an older unit, replacing a missing or damaged strain relief spring is a quick, low-cost fix that pays for itself by preventing expensive cable repairs down the road. Keep your arc stable and your equipment in top shape with this genuine Tweco accessory.
