Invert DC MIG & TIG & MMA Arc Welding Machine

MIG series welders of our company are inverter welders which adopt the latest insulated gate bipolar ransistor (IGBT) technology. the working principle is to use the big mains switch device single tube IGBT (inverter frquency can be up to 50HZ). will naked 50HZ/60HZ power frequency rectified into DC then inverter again for high frequency and step-down rectifier, through the pulse width modulation (PWM) technology for welding output with high power dc power supply. as a result of te switch power inverter technology, the weight of the welding machine and volume dropped substantially, the conversion efficiency increased by more than 30%.

the machine is satisfying your gas shielded welding demand and increases the welding function of MMA and TIG. Using digital liquid crystal display (LCD) panel, it realize the wire feeding speed and independent adjustment of welding voltage, easily adjust the welding parameters. during using gas shielded welding, it adopt unique electronic reactor circut, precisely contrl the short-circuit transition and mixed transition of welding process, make it have the excellent welding characteristics. Compared wth silicon controlled welding machine and tapped welding machine, it has the following advantages: wire feeding speed stable, light and energy saving, no electromagnetic noise. Also has little splash, good arc force, molten pool and high duty cycle characters.

the equipment is portable multi function machine, suitable for home users and professional users. it has high efficiency, electricity saving and other advantages, is suitable for various kinds requirements of metal welding.
