AccuLock™ R Consumables

AccuLock™ R consumables are designed for increased tip life, which reduces replacement frequency and related downtime. Plus, AccuLock HDP contact tips can increase life by an additional 10x or more in pulse welding applications. The longer lifespan of AccuLock contact tips means fewer human interactions within your welding cells and fewer accidental errors as a result.

With contact tip cross-threading issues also virtually eliminated, you’ll spend less time troubleshooting and more time on proactive weld quality and productivity initiatives. 

In most cases, your current tip and diffuser can be replaced with no impact to Tool Center Point (TCP), making this upgrade low effort, low risk, and high payoff. AccuLock R consumables can also be used across all your semi-automatic, robotic and fixed automatic MIG guns.

Tregaskiss® Robotic Nozzle Cleaning Stations

New TOUGH GUN® TT4A (Analog) and TT4E (Ethernet) nozzle cleaning stations power through the toughest spatter with a .95HP motor and 236 lbs. of lifting force at 95 psi.  Automated cleaning improves gas flow for reduced weld porosity, rework and scrap in robotic applications.

Keep your welding operation up and running for extended periods of time with high performance components:

  • Powerful, lubricated motor lasts up to 18M cycles at 80+ psi
  • Durable valves and cylinders rated for 10M+ cycles
  • Wire cutter can run 1M+ cycles without requiring maintenance

New standard features reduce maintenance downtime, safety incidents and costly weld defects related to anti-spatter:

  • New larger capacity anti-spatter reservoir with tethered cap and easy clean filter
  • New low fluid level indicator sends a signal to the PLC/robot when anti-spatter is running low
  • New spray containment unit reduces slip/trip accidents and reduces cleaning downtime costs
