WELDING MACHINE MMA AC TRANSFORMER SERIES
MMA AC welding machine is a type of welding machine that uses a transformer (transformer) as a source of flame in the electric arc. Technically, this type of electric welding machine uses a transformer as a medium. To change the electric current it receives. Becomes alternating electric current. Or so-called AC current. This is because AC electricity from PLN has a high voltage. Compared to the welding needs that range from 55 Volts to 85 Volts. Then it requires a step-down transformer.
In its performance, the transformer will function to change the voltage of the electric current. Which usually goes in higher than the need. Be the appropriate voltage. And can be used on the welding machine itself. To maximize its performance. Usually this type of welding transformer uses a large amount of power. Due to the high demand for electrical power used. To melt metals and electrodes in the welding process.
