AccuLock S Consumables

Challenged by increasing welder retirements and turnover?

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. Both are common costly contributors to troubleshooting, rework and production downtime.

Load and Lock for better productivity Load and Lock to reduce troubleshooting, downtime and rework Load and Lock for better productivity

  • Reduce welding troubleshooting and rework
  • Flawless wire-feed path — AccuLock S liners are locked and concentrically aligned to both the contact tip and the power pin without the use of fasteners to guarantee optimized wire feeding, which eliminates welding liner misalignment and gaps from your troubleshooting list
  • Error-proof liner replacement every time — no measuring required!
  • Steel retaining ring on diffuser helps keep threaded nozzle in place during use/cleaning
  • Coarse threaded contact tips speed tip replacement
  • Enjoy 2-3x extended contact tip life due to optimized wire feeding
  • Simplify MIG welding inventory with a Common Consumable Platform™ —Bernard AccuLock S and Tregaskiss® AccuLock R consumables share a common contact tip
