IGBT INVERTER MULTI-PURPO SEPULSE ARGON ARC WELDER
1.Four kinds of working modes including AC square wave TIG weld ,DC pulse TIG weld DC TIG weld and DC manual weld
2.Excellent performance of high frequency arc starting,success probability of arc estab lishment is close to 100% even at the moment of small current when AC TIG weld
3.Adopting IGBTinverter technology,AC&DC arc is quite stable
4.Insert electric stable arc device to avoid high frequency voltage for stable arc harming welders
5.Having fine protecting functions including overheating,undervoltage,over voltage,scarcity of phase and scarcity of water
