Features Advanced IGBT inverter technology; Designed with self-locking and non-self-locking functions for argon arc welding; Manual arc welding supports vertical-down welding with cellulose electrodes; Automatic protection functions for overcurrent, overvoltage, undervoltage and overload; High efficiency and low no-load loss, can save more than 1/3 power comparing to conventional welders; Automatic compensation for mains voltage fluctuations, strong resistance to voltage fluctuation (V±15%); Easy arc starting, low noise level, stable and reliable arc, good weld formation; For welders of over 550A, can implement carbon arc gouging, suitable for welding of stainless steel, alloy steel, titanium, etc.; Two welding processes can be accomplished in one machine, i.e. argon arc welding and manual arc welding; Standard Configurations Earth clamp 1pc Quick connector 2pcs Earth cable 2m Water-cooled welding torch 1pc Hex key 1pc Technical Parameters
