Transformer Based Step Arc Welding Machine

A transformer welding machine is an electric arc welder that uses alternating current (AC) instead of direct current (DC). This type of welder is lightweight and portable, making it ideal for those who only do occasional welding jobs.The transformer, housed in a welding machine, is used to convert the high-voltage input or, primary power, from the wall plug and this is usually from 208 to 600 volts, with a low alternating current (AC) from 15 to 55 amps.Transformer welders use a “step-down transformer.” This simple technology takes a high-voltage, low-amperage current and reverses it into a low-voltage, high amperage current. So, an AC high voltage input (110V, 220V, 380V, etc.)
