MMA-300 Digital display Arc Stick Welder DC Inverter Stick Welding Machine

230 Amp IGBT Inverter Stick Arc Welder, 100% Duty Cycle, 220/380V Dual Voltage, Compatible all Electrodes.

MMA-300 Stick arc welder is an IGBT MMA stick welding machine that adopts full bridge inverter and provides advanced control technology. This stick welder power supply provides a stronger, more concentrated, more stable arc with unmatched welding performance designed to meet all your welding needs and achieve superior welding results. The MMA-300 stick welder auto selection function automatically detects the input voltage so that you can easily switch between 220V 50/60Hz or 380V 50/60Hz input power. Adjustable arc force Settings allow you to meet your custom welding needs. The machine has no problem to push and weld 6010, 6011, 6013, 7018 electrode. It has the ability to handle various welding applications, the characteristics of long-term continuous welding, the load persistence rate is as high as 100%, and the 5.0mm electrode can be used for long-term uninterrupted welding.
