Welding machine principle
Jan 04, 2019

The high-temperature arc generated by the positive and negative poles in an instantaneous short circuit is used to melt the solder and the material to be welded on the electrode to achieve the purpose of combining them. The structure of the electric welder is very simple. To put it bluntly, it is a high-power transformer that turns 220/380V AC into a low-voltage, high-current power source, which can be either DC or AC. The electric welding transformer has its own characteristics, which is characterized by a sharp drop in voltage. After the welding rod is ignited, the voltage drops. In addition to the 220/380V voltage conversion of the electric welding machine, the secondary coil also has a tap change voltage, and there is also an iron core to adjust. The adjustable iron core electric welding machine generally It is a high-power transformer, which is made by the principle of inductance. When the inductance is turned on and off, it will produce a huge voltage change. The high-voltage arc generated by the positive and negative poles in the short-circuit is used to melt the electrode. Solder. To achieve the purpose of combining them. A voltage is applied between the electrode and the workpiece, and the arc is swept or contacted to ignite the arc, and the energy of the arc is used to melt the electrode and heat the base material.
