Controller

Welding method: constant current, constant voltage Constant transmission angle (PHA); constant current (KSR) control mode Power outage protection function: Data will not be lost for ten years after power outage The controller consists of power part and the control section. Three-stage process of heating: preheating, welding and tempering; and the stage of welding can be manual defined to increasing and decreasing stage. Every stage process can be defined individually like mode of PHA, KSR and KUR. Supporting single point or continuous welding Supporting regular and pulse starting up. Have welding current monitoring function Have current step function to automatically compensate the influence for welding current from electrode abrasion. Step function is linear increasing. Have electrode grinding control function Have breakdown protection and alarm displaying function Have power outage protection function, data will not be lost for ten years after power failure. Have alarm record save function At most 64 sets of welding specifications can be programmed . Have power components over heating protection function The air switch has functions of overload protection and leakage detection.
