TIG welder is of constant current external characteristic. Welding current will not be changed per arc length but being kept at a very stable level. It adopts PWM technology and high-power switching element IGBT (discrete) to rectify AC230V (50Hz/60Hz) voltage to DC325V, after inverting it to 45KHz, there is a voltage step-down and rectification again, stable welder current is obtained by output current feedback and adjustment
