Welding Machine are the heavy electrical machineries that are used in product manufacturing for joining of the two metals and thermoplastics by heating them above their melting point by the application of heat and pressure until it cools down which results in fusion. There are various types of such machineries with different working capacities. Welding Machine are used to make permanent rigid joints which allows the fusing of the molten materials into each other. They are provided with high powered step up transformer which increases the voltage from 220 volts to higher values. They are widely used in product manufacturing units, automotive garages and various metal fabrication industries. These devices are equipped with an electrical unit which make it very easier to control various working parameters.
