Product characteristics： 1． Utilize imported IGBT as power component, high efficiency, compared with traditional welding machine, energy-saving could be above 30%. 2． PWM technology is applied, stable welding current：Constant flow is possible no matter under freezing or heating status. 3． Direct current manual arc/ argon-arc function; one machine has two utilizations, hence you really get more than you paid. 4． High-speed dynamic responding, low splash, fine welding line. 5． Could initiate arc by high-frequency arc, high arc-initiating success rate. 6． Has intelligent protection system: when electronic network is abnormal, temperature is too high or current is overloaded, the protection system alarm timely to ensure that the welding machine is ?in a whole skin?.
