Welding Robot Systems
G4 series (WG4 / WGH4 / G4)
Overview
The G4 series 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.
WG4: Welding power source integrated type (TAWERS)
WGH4: High current welding power source integrated type (TAWERS)
G4: Welding power source separated type
Features
-
Reduces spatter by approximately 60% with the MTS-CO2 welding method (WG4)
-
Welding control optimization according to robot posture reduces cycle time (WG4 / WGH4 / G4)
-
The teach pendant equipped with a touch panel further improves ease of use (WG4 / WGH4 / G4)
-
Eliminating the need for an external step-down transformer reduces the man-hours required for setting up at sites outside Japan (WG4 / WGH4 / G4)
-
The conformance to the OPC UA standard facilitates integration with peripheral devices (WG4 / WGH4 / G4)
-
High current up to 500A, suitable for thick plates (WGH4)
Advanced welding method "AWP4"
AWP4(Active Wire Process 4) can be used with TAWERS (WG4) to improve productivity through low spatter and high-speed welding.
Assumed Customer Challenges
Spatter reduction
The MTS-CO2 welding method, which is the basic function of TAWERS, has significantly evolved, demonstrating its spatter reduction effects in the high-current range.
Ease of use
The teach pendant equipped with a touch panel has enabled more intuitive and easier operation. Welding Navigation also allows easy condition setting.
Welding defects
These models enable the analysis of welding results in a more detailed manner than conventional models. Users can expect enhanced welding quality through the in-depth analysis of welding results.
Features and Effects of WG4 / WGH4 / G4
Easy to set up at factories outside Japan without the need for a step-down transformer (WG4 / WGH4 / G4)
- 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
* When setting up these robot systems in Japan, an input power supply is required according to the specifications of each model.
Please note that if you cannot prepare the required power supply, then a separate transformer is required to convert the input voltage to 200 V.
Enhanced compatibility with peripheral devices by conforming to the OPC UA global standard for industrial interoperability (WG4 / WGH4 / G4)
- OPC UA-compliant devices possess connection compatibility, thereby enabling secure and seamless data exchange between them
* OPC UA-compliance is an optional function. In order to ensure data exchange between devices, all of them must be OPC UA-compliant.
The software-based safety mechanism enables more flexible and safer work environments (WG4 / WGH4 / G4)
- 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
