Electric welder
Jan 25, 2019

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 combine the objects to be contacted. Its structure is very simple, it is a high-power transformer.

Electric welding machines are generally divided into two types according to the type of output power, one is AC power, and the other is DC power. They use the principle of inductance, the inductance will produce a huge voltage change when switching on and off, and 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 make them achieve atomic bonding.
