QUICK LOAD Liner AutoLength System

The QUICK LOAD® liner AutoLength™ system is designed specifically to minimize downtime, wire feeding and quality issues commonly associated with the liner being cut to an incorrect length.

Short liners are a common root cause of poor wire feeding. Further, a short liner does not have a chance of properly seating in the retaining head — often resulting in “bird-nesting” of the welding wire or premature contact tip failure and wear.

Wire feeding challenges reduce efficiency of the welding process and cause undesirable (and expensive) downtime. A system upgrade to this new innovative product can help improve welding efficiency and reduce costly downtime.  

How It Works

  • Housed inside the power pin, this spring-loaded module applies constant forward pressure on the liner, keeping it seated properly in the retaining head
  • Allows for up to one-inch (2.54 cm) forgiveness if the liner is too short
  • Accommodates liner movement during welding 

How It Increases Productivity

  • Reduces issues caused by the liner being cut to an incorrect length
  • Decreases burn-backs caused by misalignment between the liner and the contact tip
  • Improves wire feedability by enhancing wire alignment with the contact tip

Important Note: The QUICK LOAD liner AutoLength system is designed specifically for use with QUICK LOAD liners.
