New Generation

for Tawers Arc Welding

The new G4 controller for: 

  • Versatile Features for Global Standards
  • Seamless Connectivity 
  • Next-Generation Welding Performance
  • Boost Uptime with Enhanced Maintenance Functions
  • Teach Pendant touch panel Adoption

Highly accurate and efficient welding experience

The maximum speed of each axis has improved by up to 27% by fine-tuning acceleration/deceleration control. The operation algorithm has also been reviewed to improve locus accuracy. These improvements can significantly reduce work losses that affect productivity in demanding workplaces. Further, this helps improve product quality, which is indispensable to business success.

Reduce Takt Time with Improved Acceleration and Maximum Speed on Each Axis

Welding is also enhanced, for example with one process reducing spattering by up to 62% to improve quality.

Easier to use with touch panel and 3D display

Equipped with a touch panel with a resolution 1.6 times greater than that of G3, which can be operated with work gloves on, and a 3D engine adopted for the first time, this controller realizes a high-definition 3D display and intuitive operations, therefore making it easier to use.

For manufacturing where everything is connected

The G4 controller realizes various functions not available with G3 by utilizing its high speed and parallel processing capabilities. In particular, the adoption of open communication specifications called OPC UA and software-based functional safety with excellent flexibility are typical examples. Connection with new sensors for safety and other devices for data collection or automation will be made easier without any compatibility restrictions with additional devices or hardware limitations.

Cables arranged on the back to save space

The primary side input line and conncetion cables are arranged on the back, and the TP cable is arranged on the front to reduce projections on the side.
