Embodiment
The structure of electric welding machine energy-saving safeguard device, connection principle and control process are made below in conjunction with accompanying drawing further detailed
Explanation：
As seen from Figure 1, the present apparatus by master switch, power converting circuit, control circuit, sample circuit, start-up circuit and
Six parts of electric welding machine are formed, and in addition to electric welding machine, other parts are arranged in a casing, the electrical connection of device various pieces
Relation is：Master switch 1 is connected on power supply and in the main circuit of electric welding machine 5, control circuit 3 gathers and utilizes sample circuit 4, startup
The signal of circuit 6 and power converting circuit 2, it is real by each circuit element and component contacts being combined, being gathered the utilization of signal
Effective control by setting time to master switch 1 is applied, it is controlled to reach electric welding machine 5, realizes energy-saving effect.
From Figure 2 it can be seen that the specific wiring of the present apparatus, the course of work are：After tri- branch circuit parallel connections of A, B, C of control circuit 3
