This machine adopts the innovative Inverter technology that benefits from the development of this theory on the supply of the electrical flow and the electrical components that allow its operation. Using the high-potential MOSFET component converts a frequency of 50/60 Hz to 100 kHz, then reduces the voltage and switches it to give a high electrical power thanks to PWM technology. Due to the sharp reduction in the weight and volume of the main transformer, the efficiency is increased by 30%. The appearance of INVERTER technology is considered a revolution in the welding industry. OREWORK INVERTER welding is efficient, energy efficient, compact, arc stable, good force compensation capacity and multi-purpose. Can weld stainless steel, coal iron, mixed iron, copper and other metals. OREWORK Inverter welding can use different types of electrodes, alkaline, acids and fibers. It is lightweight, compact, easy to install and use.
