| IGBT ZX7 Series inverter welder have several types , such as ZX7315/400/500 /630. And each type covers three models: S (MMA),ST(MMA/Contact arc start TIG),STG(MMA/ Contact arc start TIG/ HF arc-start TIG ).This series are wildly Applied in electric power industry, petrifaction construction, pressure container,ship-building industry and manufacturing enterprise , etc. 1)Adopt advanced electronic components and reliable controlling circuit;stable current,high welding performance. 2)Multi-purpose welder with both TIG and MMA function 3)High frequency switch,small measurement,portable. 4)Adjustable heat arc-start function improves the arc-start performance of welding machine 5)Auto-lock and unauto-lock function for TIG 6)Digital display , Welding current can be exactly forecasted . 7)High rated cycle duty saves 30% electricity than that of conventional welder 8)Soft-swich technology,high performance efficiency 9)Emendation techonology for passive power factor, high power factor 10)Adjustable arc force follow the length of welding cable, implementing remote welding . 11)Having selectable wire and wireless control mode Wire on machine 12)Adjustable arc-off time of TIG 13)Machine that over 500A have Carbon arc air gouging function . 14)Omnidirectional welding carbon steel ,stainless steel
