2. Hi-frequency Welding Power Source

• Metal to Metal Arc welding is one of the most widely used welding technique in industry. The conventional welding units are either transductor type or thyristor types.The high frequency power sources for welding units provide the advantage of better weld quality, small size, low cost and portability.

• The unit operates from single phase AC and is basically a switch mode converter providing isolation and a low voltage DC suitable for welding. The electronic feedback control ensures constant welding current in spite of arc length variations. Automatic compensation against input line voltage variations ensure stable output current.

• Hot start feature for positive arc striking and anti stick feature to prevent freezing of electrode in the weld pool. Protection against input over and under voltage, over current, over temperature.
