ABSTRACT:
An arc welding apparatus is constructed of: a welding transformer 1, wherein a first tap T1 is provided at a point of half N/2 of the total number of turns N of the secondary winding of the transformer 1, the first tap T1 is connected to the electrification section 9 of a manual welding holder 8, a second tap T2 is provided at a point of N1 turns from the start Ts of the secondary winding, the second tap T2 is connected to a second thyristor 3, a first thyristor 2 and a third thyristor 4 are connected across both ends of the secondary winding, a third tap T3 is provided at a point of half N1/2 of N1 turns of the secondary winding and the third tap T3 is connected to a CO.sub.2 arc welding torch 10; a control circuit 6 for controlling these thyristors 2-4, a gate signal switchover circuit 5 for executing switchover between gate signals of the thyristors 2-4; and a reactor 7 for smoothing a welding current. The arc welding apparatus executes switchover between manual welding and CO.sub.2 welding by means of thyristors, thereby manufacturing the apparatus at low cost and achieving improved reliability.
