Products' Characteristic Perfect welding quality, nice welding line and perfect welding quality are achieved for improvement of electric arc by using special reactors. High ratio of arc-igniting 100% ratio of arc igniting is achieved by using special circuit of arc ignition. Stable welding Anti-interference & anti-undulation capacity is strong by using rapid reactive circuit and EMC treatment. Predefining function it is easy for beginner to handle with digital display of welding current & voltage and data predefining function. Splash is deeply reduced by using dynamic welding characteristic control circuit. Area influenced by heating is smaller, so welding distortion is much less too. Power source is deeply saved with smaller dimension & lighter weight.
