Digital IGBT Inverter Technology: Advaced unique IGBT control mode improves the reliability of welding machine. Keep arc stability, consitant welding current. More powerful :Up to 165 more amps, Ideal performance for most 6010, 6011, 6013 and 7018 rods. Easy to Operate:So easy to use that it can be used by novice or master welder. No matter is man or woman welders. Digital Control:Select diameter of welding electrodes, the recommend welding current will be automatic switched into, also you can adjust welding current according to your welding habit. Safe and Stable:Automatic compensation for voltage fluctuation, over current protection, over load protection, temperature control. Automatic Hot Start and Auto Adaptive Arc Force to Minimize electrode sticking in the puddle without compromising arc stability or increased spatter.
