AccuLock S Consumables

Less tip changes. Less troubleshooting. More products out the door.

As you support more inexperienced welders, choosing equipment with fewer points of failure and simplified maintenance can reduce training and shorten your troubleshooting list.

Bernard® AccuLock™ S consumables are designed to address liner trim length errors and erratic wire feeding in semi-automatic welding applications, while increasing contact tip life. Both are common costly contributors to troubleshooting, rework and production downtime.

Transform the way you manage your MIG welding gun consumables. AccuLock™ S consumables for better productivity.

Reduce Errors

  • Error-proof liner trimming every time — no measuring required!
  • Match the color of the power pin cap washer and liner shrink wrap to prevent errors
  • The liner is locked and aligned at the front and back of the gun to provide a flawless wire feed path

Increase Productivity

  • Flawless wire-feed path — front-loading AccuLock S liners are locked and concentrically aligned to both the contact tip and the power pin to ensure optimized wire feeding
  • Eliminates welding liner misalignment and gaps from your troubleshooting list

Longer Contact Tip Life

  • 2-3x extended contact tip life
    • Less tip wear due to optimized wire feeding
    • 60% of contact tip buried within diffuser away from the heat of the weld
    • Shielding gas cools contact tip tail
  • Mating tapers on both tip-to-diffuser and diffuser-to-neck connection for good electrical conductivity
  • Steel retaining ring on diffuser helps keep threaded nozzle in place during use/cleaning
  • Coarse thread on contact tip speeds tip replacement
  • Simplify MIG welding inventory and reduce errors with a common contact tip. Bernard AccuLock S and Tregaskiss® AccuLock R consumables share a common contact tip
