The door sheet welding machine uses the high-temperature arc generated when the positive and negative poles are short-circuited instantaneously to melt the solder and the material to be welded on the electrode, and the purpose of combining the objects to be contacted. Its structure is very simple, it is a high-power transformer.

Electric door welding machines are generally divided into two types according to the type of output power, one is AC power and the other is DC. They use the principle of inductance, the inductance will produce a huge voltage change when the inductance is turned on and off, and the high voltage arc generated when the positive and negative poles are short-circuited instantaneously is used to melt the solder on the electrode to achieve the purpose of atomic bonding.

Principle

It uses the high-temperature arc generated when the positive and negative poles are short-circuited instantaneously to melt the solder and the material to be welded on the electrode to achieve the purpose of combining them.
