Abstract

PURPOSE: To easily improve cleaning effect in AC TIG welding by providing rectifier elements respectively between the two secondary windings provided to a single phase transformer for welding and a welding load, and providing a difference in the number of turns of the secondary windings.
CONSTITUTION: The respective numbers of turns of the secondary windings 10a, 10b of a leakage transformer 10 are defined as N1, N2, impedances as Z1, Z2 and no-load voltages as E1, E2. When set N1>N2, there is obtained Z1>Z2 and the secondary short-circuiting currents of the windings 10a, 10b go E1/Z1, and E2/Z2. Namely, when the tungsten electode of a welding torch 13 in which electric current is intrinsically difficult to flow is positive and the welding load is negative, the impedances of the windings are small and therefore they act flow more currents. When the tungsten electrode in which electric current is easy to flow the is negative and the welding load is positive, the impedances of the windings are large and therefore they act so as to suppress the flowing currents. Hence, The DC component of the AC TIG welding current is reduced and sufficient cleaning effect is accomplished.
