What Is A Plasma Arc Welding Machine?

As one of the Plasma Welding Machine Suppliers, let us introduce the Plasma Arc Welding Machine.Plasma arc welder, like argon arc welder, can be divided into manual welding and automatic welding according to the operation mode. Manual welding equipment consists of welding power source, welding torch, control circuit, gas path and cooling system; automatic welding equipment consists of welding power source, welding torch, welding trolley, control circuit, gas path and cooling system.

Plasma Arc Welding Machine

The main component of the electric welder is a step-down transformer. The two ends of the secondary coil are the welded workpiece and the welding rod. When working, the arc is ignited, and the welding rod is welded into the gap of the workpiece at the high temperature of the arc. Since the iron core of the electric welding transformer has its own characteristics, it has a characteristic that the voltage drops sharply, that is, the voltage drops after the welding rod is ignited; when the welding rod is stuck and short-circuited, the voltage drops sharply.

In the welding operation, although the currents in the circuit are equal everywhere, the resistance is different at the unfixed contact due to the different resistances everywhere (this resistance is called contact resistance), according to the law of thermal effect of current (also called Joule's law) It can be seen that when the currents are equal, the heat resistance is higher in the portion where the resistance is larger. Therefore, when the contact of the electrode of the electrode is the contact resistance of the contacted metal body at the time of welding, the electric heat generated at this portion is naturally also The most, in addition, the electrode is a lower melting alloy, naturally easy to melt. The molten alloy electrode core is bonded to the object to be welded, and after cooling, the welded object is bonded together.

Our company also produces a variety of hardware products, such as Panasonic Plasma Cutter, Cast Iron Stick Electrodes and Portable Electrode Oven. Welcome everyone to come to consult and order.
