ARC Welding Machine New PCB 2 IGBT » ELCMARTAn IGBT welding machine is a modern arc welder that uses Insulated Gate Bipolar Transistors (IGBTs) in its main circuit to convert AC power to DC power more efficiently and precisely. This technology makes the welder compact, lightweight, and energy-saving compared to older, larger transformer-based machines. IGBTs are ideal for welding because they are high-speed semiconductor devices that combine the ease of control of a MOSFET with the high-current and high-voltage capabilities of a bipolar transistor.
