Argon arc welding is tungsten inert gas arc welding, refers to the industrial tungsten or active tungsten as the non-melting electrode, inert gas (argon) as the protection welding method, referred to as TIG.Argon arc starting adopts high pressure breakdown arc starting mode. Firstly, high frequency and high pressure are applied between the electrode needle (tungsten needle) and the workpiece to break through argon gas to make it conductive. Then, continuous current is supplied to ensure the stability of arc.
Argon arc welding machine in the main loop, auxiliary power, drive circuit, protection circuit and other aspects of the working principle is the same as hand arc welding machine.
