Abstract

PURPOSE: To make possible setting of welding specification with a simple constitution without requiring multiple switch operations and skill by combining the specified welding specifications by select means according to the kinds of the arc welding having been set by a setting means and controlling the outputs thereof by output means.
CONSTITUTION: For example, in a TIG welding machine, a select switch 20 is set at 21 of the contacts 21W26 which permit the selection of six kinds, (crater filler weld), (repeat), (not), (manual weld), (arc spot weld), etc. As a result of this, the signal of the output V1 becomes OV and the other signals become VC (high level). These and the signal from a start circuit 2 cause a decision circuit 27 to operate. Relays 8, 9, 28 are then operated to control a shielding gas operation circuit 11, high-frequency generating circuit 13 and output control circuit 12. Even when sequence has incrased, logic circuits increase but this may be coped with by increasing one switch contact.
