Hot wire type arc welding device

Abstract

Abstract PURPOSE:To make the reduction in size at a low cost possible by flowing wire heating current and arc current from one unit of an electric power source by the use of transistors. CONSTITUTION:Arc current I1 flows in a route of an electric power source 13, a transistor TR1, base materials 3, a molten pool 8, a non-consumable electrode 1 and a shunt 18, and generates the arc 4. Wire heating current I2 flows in the route of the power source 13, a transistor TR2, a power feed tip 7, a wire 5, the pool 8, the arc 4, the electrode 1, and the shunt 18, and heats the wire 5. These currents are controlled by the TR1, TR2 so that the applied voltage V for wire heating of constant voltage characteristics and the full arc current I0 of constant current characteristics are obtained.
