Hwashi experts teach you spot welding skills
The Hwashi spot welder uses the high-temperature arcs generated by instant short circuits of the positive and negative poles to melt the solder and the materials to be welded to the electrodes in order to combine them. The structure of the spot welder is very simple. Frankly, it is a high-power transformer that converts 220V AC into a low-voltage, high-current power supply, which can be DC or AC. Welding transformers have their own characteristics, i.e. the voltage drops dramatically.
When the electrode ignites, the voltage drops. In addition to the primary 220/380 voltage conversion, the secondary coil also has a tap conversion voltage when adjusting the operating voltage of the spot welder, which is also regulated by the iron core. Adjustable iron core welders are usually high-power transformers, which are made according to the inductive principle. When switched on and off, the inductance will produce a significant voltage change. It uses high pressure generated by positive and negative poles in instantaneous short circuits. Arcs are used to melt solder on electrodes in order to combine them. Apply voltage between the electrode and the workpiece to ignite the arc by scratching or touching it, and the energy of the arc is used to melt the electrode and heat the master material.
Spot welders are usually divided into two types of output power, ac power and DC power. It is made using inductive principles. When switched on and off, the inductance will produce a significant voltage change. High-voltage arcs generated by transient short circuits of positive and negative electrodes are used to melt solder on the electrode to achieve their binding objectives.
