Weld Timer Integrated in Robot Controller
by Nachi
The intelligent all-in-one package
- Servo gun, weld timer and other welding functions are all integrated in robot controller.
- Easy to set up welding conditions. Excellent for controlling weld quality.
- Air cooling for superior maintainability and reliability.
High-speed
- Robot controller and timer controller are fully integrated.
- Increased speed 3.5% by thoroughly reducing wasted I/O processing time between weld timer and robot controller. (compared to regular timer)
- Greater productivity coupled with high-speed of SRA series.
Improved Operability & Full Traceability Function
- All weld timer functions can be set from the robot's teach pendent (welding parameters, stepper counter, welding history, and welding conditions)
- Welding history of up to 9,999 welds possible.
- History data can be exported.
- Track signs of abnormalities on graphic display of welding current.
