Abstract

PURPOSE: To let initial arc starting be done surely without producing any spatter by short-circuiting a filler core wire and the base metals to be welded while supplying starting electric power of constant electric current between both and changing over the starting electric power to a welding electric power source after the generation of an arc.
CONSTITUTION: Sending-out of a filler core wire 16 and spouting of an inert gas 21 are accomplished by switching-on of a welding torch. At the initial arc welding, the core wire 16 is short- circuited to the base metals 18 to be welded, and at this same instant a starting electric power source 32 of constant current is turned on, but predetermined short-circuiting current just flows; therefore the melt-cutting of the core wire 16 does not occur and no spatters are produced. Next, a voltage detecting circuit 36 detects the short-circuit and supplies a reverse run signal of a DC motor 28 to a control electric power source 8, by which the core wire 16 is pulled up and an arc is generated between the same and the base metals 18. When this arc voltage becomes of a proper value, a welding signal is supplied from the circuit 36 to a welding electric power source 22, a starting electric power source 32 and a high-frequency high-voltage circuit 34, by which the core wire 16 is sent out and the electric power source 22 of a constant voltage is turned on in place of the electric power source 32, thus desired MIG welding is started.
