Product Description This series welding machine is the constant current tungsten electrode inert gas shielded welding machine, used for AC/DC argon arc welding(AC/DC, TIG). At the same time, it is also an outstanding manual welding machine. Lt outputs square wave current. Zero point passing through speed of current is quick. Self arc-steadying performance is good. Lt has unique automatic balancing controls for automatic adjusting the depth of fusion of AC aluminum welding and the intensity of deoxydation capability, and ensure the lifetime of tungsten electrode. Lt has the functions of spot welding, short welding. Long welding and current decaying. Peak value, fundamental value, frequency and pulse width can be adjusted respectively when making pulse welding. Lt can be used for the precision welding.,
