*1 Set value of “START signal input decided 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 H-ST1
signal is received and welding is started, this signal is turned off.
