3G Modular Robotic Weld Guns

3G the worldwide reference to improve efficiency and reduce costs.

The revolutionary 3G modular system allows four gun variations to be created from 9 shared modules, 7 specific modules and 2 plug and play arms.

Using ARO’s unequalled modular and servo gun expertise, the family of 3G guns has up to 60% fewer parts than conventional gun designs and there is a high degree of component commonality between all of the 3G gun types.

3G Light

lightweight range of 3G < 100kG designed for low payload and small footprint robots.

  • Same welding current capability (max welding current and permanent current)
  • Same welding force capability
  • Same maintainability – only 3 tools needed – MTTR< 10min.
  • Same modularity (brackets / mirror guns / power connections / actuators ..)

The 3G gun bodies

The revolutionary 3G modular system allows four gun variations to be created from nine shared modules, seven specific modules and 2 plug and play arms.

Rapid and easy assembly

A fully functioning gun can be assembled quickly from a small number of standardised components. Once assembled the arms simply plug in and the whole assembly is ready for inspection:

  • Only 3 Allen keys are needed!
  • MTTR is less than 10 minutes.
  • Delivery times are dramatically reduced.
