The G4 Series robot Controller is flagship models of welding robots. These robots solve customer challenges through a variety of approaches, such as by providing further evolved weldability, ease of use, and safety.

Welding control optimization according to robot posture reduces cycle time
- The basic performance has been enhanced through improved CPU performance and memory capacity
- The maximum speed of each axis has been improved by up to 27% (compared to the G3 controller)
The new teach pendant equipped with a touch panel has further improved ease of use
- A touch panel has been installed for the operation display without changing the basic operation
- The panel can be operated by users wearing gloves
- The display features a tidy design with integrated functional buttons
- The characters on the display can be enlarged, reducing the risk of pressing the wrong keys and significantly improving visibility
Easy to set up at factories outside Japan without the need for a step-down transformer
- There is no need for an external step-down transformer, which can achieve reduced costs and a more compact footprint
- Failure risks can be reduced with fewer connected devices and cables
Enhanced compatibility with peripheral devices by conforming to the OPC UA global standard for industrial interoperability
- OPC UA-compliant devices possess connection compatibility, thereby enabling secure and seamless data exchange between them
The software-based safety mechanism enables more flexible and safer work environments
- Conventional hardware limit switches for manipulators have been replaced with software-based monitoring
- Safety signals such as for emergency stop can be exchanged by using communication signals
- Complex safety circuits, which were conventionally designed by combining PLCs, switches, and relays, can now be configured with software, thereby facilitating specification changes
