OVERVIEW

Restore Smooth Feeding with the Tweco Composite Spring

Is your MIG gun acting up? Inconsistent wire feeding or a sticky trigger can often be traced back to a small, worn-out spring. The Tweco 400562-048 Composite Wire Feed Spring is the direct replacement you need to get your gear back in fighting shape. Welding is all about consistency, and if your wire isn't feeding smoothly because of a weak spring, your welds are going to suffer. This genuine Tweco part is built to replace the tired spring in your system, restoring the tension and response you expect from your equipment.

Why choose a composite spring? Composite materials are tough. They handle repetitive stress exceptionally well and don't rust or corrode like some bare metals can in harsh shop environments. This means you get a longer service life out of the part and fewer headaches down the road. Installing this spring is a straightforward maintenance task that can save you from the frustration of mid-weld interruptions. Don't let a five-dollar part cost you hundreds in downtime or reworked parts.

This spring is specifically designed for Tweco wire feed systems. It isn't a generic "one-size-fits-all" hardware store spring; it has the exact tension rating and dimensions required for your welder. Whether you are doing automotive repair, structural fabrication, or general maintenance, keeping your MIG gun's internal components fresh is key to producing professional results. Keep a spare in your toolbox so you are never caught off guard by a mechanical failure.

Benefits for the Welder:

  • Reliable Feeding: Restores proper tension to prevent wire slippage.
  • Durable Material: Composite design resists wear and fatigue.
  • Easy Fix: Direct replacement part for quick maintenance.
