Abstract

단락된 텅스텐전극(28)을 모재료(29)로부터 떼어내는 용이한 작업에 의해 아아크 발생후의 정상의 출력전류의 대소에 의하지 않고, 잡음을 발생시키는 일이 없이 확실히 또한 안정적으로 아아크개시 될수 있게한 것으로서 용접부하(27)의 텅스텐전극(28)을 모재료(29)에 단락시켜서 부하급전을 개시하는 아아크 개시의 출력전류 설정용의 개시전류 설정신호를 출력시키는 개시전류 설정기(32)와 아아크 개시후의 정상의 출력전류 설정용의 정상저류 설정신호를 출력시키는 정상전류설정기(33)과 아아크 개시에 개시전류 설정신호를 출력전류 설정신호로서 출력시키고, 아아크 개시시에 의해 전극(28)이 모재료(29)로부터 떨어진 직후의 소정기간 양설정 신호중의 전류 출력이 크게 되는 한쪽을 출력전류 설정 신호로서 출력시키고, 소정기간의 경과후에 정상전류 설정신호를 출력전류 설정신호로서 출력시키는 설정신호 출력전환수단을 구비한 티그 아아크 용접기이다.The easy operation of detaching the shorted tungsten electrode 28 from the mother material 29 allows the arc to be started reliably and stably without generating noise, regardless of the magnitude of the normal output current after arc generation. The start current setter 32 and the arc which output the start current setting signal for setting the output current of arc start which short-circuits the tungsten electrode 28 of the welding load 27 to the base material 29, and starts load feeding. The normal current setter 33 for outputting the normal storage set signal for setting the normal output current after start and the start current set signal are output as the output current set signal at the start of the arc. One of which the current output of the predetermined signal for a predetermined period of time immediately after being separated from the parent material 29 becomes large is output as an output current setting signal, and normal after the predetermined period has elapsed. Flow is a TIG arc welding machine and a setting signal output switching means for outputting a set signal as the output current setting signal.
