Self adjusting manual & automatic welding machine

MMA-200

         Self adjusting manual & automatic welding machine

• High Inverter frequency greatly reduces the weight of the welder.
• Great reduction in magnetic and resistance loss obviously enhances the welding efficiency and energy saving effect.
• Switching frequency is beyond audio range, which almost eliminates noise pollution.
• Advanced control technology meets various welding application and greatly improves the welding performance.
• It can be widely used in acid and electrode welding.
• Easy arc starting. less spatter, stable current and good shaping.
• Efficiency, energy saving, portable, stable arc, high no-load voltage, and with good compensation of arc force, are able to meet various welding requirement in field work.
