Page 11: Machine Description
MACHINE DESCRIPTION The welding machine is a rectifier adopting the most advanced inverter technology. The development of inverter welding equipment profits from the development of the inverter power supply theory and components. The inverter welding power source utilizes high-power component single tube IGBT to transfer 50/60Hz frequency up to 15KHz, then reduce the voltage and commutate, and output high-power voltage via PWM technology. -
