The electric welder uses the high-temperature arc generated by the positive and negative poles in an instantaneous short circuit to melt the solder and the material to be welded on the electrode to achieve the purpose of combining them. The structure is very simple, it is a high-power transformer. The welding machine can be divided into two types according to the type of output power, one is AC power; the other is DC. It is made by the principle of inductance. When the inductance is turned on and off, a huge voltage change is generated. The high-voltage arc generated by the positive and negative poles in the instant short circuit is used to melt the solder on the electrode to achieve the combination. The purpose of the welding machine can not be ignored during maintenance and maintenance.
