*1 Set value of “START signal input decision delay time.” Refer to “4. (6) Switch Select Screen.”
*2 Welding data creating time (approx. 60 ms for the first condition change or approx. 30 ms for the second or later change).
Refer to “4. (6) Switch Select Screen.”
*3 Set value of “END signal output time.” Refer to “4. (6) Switch Select Screen.”
*4 Set value of “GOOD/NG signal output time.” Refer to “4. (6) Switch Select Screen.”
*5 The LOST signal is turned on concurrently with the ON timing of the END signal. The output is kept, and when the START
signal is received and welding is started, this signal is turned off.
