3G Modular Robotic Weld Guns
3G the worlwide 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.
3G Robotic Weld Guns Features
- Reduced investment in spare guns required – 3G built in simplicity, leads to reduced MTTR.
- Reduced costs for spare parts due to standardisation of parts.
- The full cover defines the 3G model precisely for offline programming – No surprises when installing the gun on the line.
- No BSP or NPT fittings – Easy worldwide implementation and tool transferability.
- Dramatic reduction in component diversity and storage requirements. Up to 60% fewer parts than a conventional gun design.
- Less in house repair engineers required. Concept relies on replacing modules by non-specialised workforce.
- Easy trouble-shooting due to single side mounting and modular components.
- Same basic body – save costs and easier late stage design changes.
- Gun cover removes need for expensive gun bags.
- Gun body easily converted from C to X or from copper to aluminium arms by swapping modules.
- Arms are “plug and play”, and can be adapted without touching the gun body.
Weld Guns Library
A large library of Robotic Weld Guns, with brackets (STEP files) is available online to perform CAD simulations at the earlier stage of your project.
