Advanced MIG Gun Consumable System Maximizes Productivity and Weld Quality

AccuLock S Consumables from Bernard work together as a complete system, improving performance and minimizing – if not eliminating – the most common gun maintenance issues.

The AccuLock S Consumable System from Bernard includes a contact tip, nozzle, gas diffuser, liner, and power pin and power pin cap. To solve bird-nesting, burnback and erratic arc issues associated with poor wire feeding in semi-automatic MIG welding, the system locks in place and concentrically aligns the liner with the power pin and contact tip for a flawless wire feeding path with no gaps or misalignments. No liner measuring is required during installation or replacement. Welders simply cut the liner flush with the back of the power pin for perfect liner trimming every time.

The AccuLock™ S Consumable System from Bernard (Beecher, IL) builds on proven consumable technology and adds advanced design features that ensure higher productivity and optimized wire feeding, while also simplifying installation and maintenance. This system includes a contact tip, nozzle, gas diffuser, liner, and power pin and power pin cap. “AccuLock S Consumables represent a revolutionary improvement for users of industrial MIG guns,” said Linda Ray, the vice president and general manager of Bernard. “These consumables work together as a complete system, improving performance and minimizing – if not eliminating – the most common gun maintenance issues.” To solve issues associated with poor wire feeding in semi-automatic MIG welding, such as bird-nesting, burnback and erratic arc, the system locks in place and concentrically aligns the liner with the power pin and contact tip for a flawless wire feeding path with no gaps or misalignments.

There is no liner measuring required during installation or replacement. Welders simply cut the liner flush with the back of the power pin for perfect liner trimming every time. Combined, these features decrease the risk of improper installation that could lead to costly downtime to address poor weld quality or liner replacement. The contact tips add to the ease of installation by featuring coarse threads that easily mate with the gas diffuser, lessening the chance of cross-threading and speeding contact tip replacement. AccuLock S Consumables are designed to reduce heat buildup for long product life: 60 percent of the contact tip is buried in the gas diffuser to protect it from heat damage, while shielding gas helps cool the contact tip tail. The tapered design of the consumables tightly lock conductive parts together to minimize electrical resistance and further reduce heat buildup.
