A.C. Inverter Control Devices
- High quality actualizing welding
Spattering control effect
Showing power in the plated steel sheet
Strength electrification of welding current is possible
- Automation correspondence
While change of 127 conditions welding, possibility.
Welding current can be control long way by analog signal
- Improvement of welding speed
Can be cooling time control ‘mm/second’ short cycle
- Decrease of Flicker
Three phase circuits bala
