electric welder
Electric welding machine is to use the high-temperature arc generated when the positive and negative electrodes are short-circuited, to melt the solder on the electrode and the material to be welded, so as to combine the contacted materials. Its structure is very simple, it is a high-power transformer.
Welding machines can be generally divided into two types according to the types of output power, one is AC power supply and the other is DC power supply. They use the principle of inductance, which will produce a huge voltage change when it is turned on and off, and use the high-voltage arc generated when the positive and negative electrodes are short-circuited instantly to melt the solder on the electrode, thus achieving the purpose of atomic bonding.
