Earth Clamp For Electric Welding As one of the Plasma Welding Machine Suppliers, let's talk about the use of earth clamps for welding.Electric welding is a welding operation that is realized by using an electrode to melt a place where a metal part needs to be joined by an arc. The working principle is: the voltage is reduced by the transformer in the electric welding machine, the current is increased, and the electric arc generates a large arc heat to melt the electrode and the steel, and the welding rod melts to make the fusion between the steels higher.Arc welding is the most widely used welding method, including hand arc welding, submerged arc welding, tungsten gas shielded arc welding, plasma arc welding, and gas metal arc welding. Because the arc welding uses a power source, the high-temperature arc generated by it is prone to fire and explosion, and the danger is high. The function of the Earth Clamp is: if there is no grounding, leakage will occur, and the leakage current will conduct electricity through the human body - the earth, which will cause personal injury. So it must be grounded. The grounding wire is to form a loop, otherwise there is no loop, there is no current, and no current can be arc welding.
