Welding machineFeatures: Special design for quakeproof, moisture-proof, dustproof and heavy duty cycle, it is suitable for working in electric power construction, chemical construction, oil field construction and so on heavy industry which requires move-frequent in bad environment. All the key parts like IGBT module, integrated circuit, relay, rectifier and so on are world famous brand ones which have high reliability. Adopting the soft switch technology, improved the IGBT and its reliability. It is suitable for DC/TIG and stick welding. Arc sticking have high reliability. Pre and post flowing. Current up and down slop can adjust. TIG welding, time control for spot welding, min. current 10A Two type of manipulate :Auto and manual
