Abstract
PURPOSE: To provide a highly precise groove copying at an arc generating spot, left-and-right deflecting arc voltage are detected to drive slide unit. This means is not affected by external disturbance such as arc heat or arc light.
CONSTITUTION: A first left-and-right deflecting arc voltage is sample-held in sample and hold circuits 22 and 21. Both deflecting voltages are half added to a reference- voltage producing circuit 23, and a reference voltage in a center position is calculated. At a second deflection, the reference voltage is compared to left-and-right deflecting arc voltage in compared 24, and left-and-right control relays 18 and 19 are turned on to close a relay contact 28. Then a comparative error voltage is made zero by driving a motor 26 for driving slide unit. Such controlling operation, if used about one cycle per 10 seconds, enables a highly percise groove copying control in a normal TIG welding speed
