The utility model when non-welded condition, maybe when surpassing certain hour and stop to weld, the first wire-wound group of welding transformer and the automatic disconnection of external power line, no open circuit loss is saved a large amount of electric energy.Simple and practical.
Description of drawings
Fig. 1 is the utility model electrical schematic diagram.
The specific embodiment:
As shown in Figure 1, the DC welder main body is a transformer B
1, its primary coil connects each phase line of three phase mains respectively, and secondary coil becomes full-wave rectification to be attempted by between welding gun and the ground through silicon diode, forms huge welding current when welding.When the utility model external power is connected because J

2, be in off-state, welder transformer B
1Primary coil does not have electricity, when welding gun with contact after, when promptly being in welded condition, relay J Z work, charging capacitor C begins charging.JZ
1Connect, the three normally opened contact conductings of A.C. contactor J, electric welding machine is started working, and when the welding gun short time stops to weld, as changing welding wire, ajusts welding position etc.Relay J Z is discharged by capacitor, still keeps conducting state, and welder transformer is had all the time, be in the wait welded condition, when the time also longer than discharge cycle does not weld, the JZ outage, the contactor outage, welder transformer and external power line disconnect, and play power savings.
