*1 The start signals 1ST and 2ND are used for welding start.
*2 Start signal 1ST decision delay time. Refer to “4. (6)
(d) START signal input decision delay time.”
*3 Welding data creating time. About 60 ms for the first condition change or about 30 ms for the second or later change.
*4 After the initial current start signal H-ST1 is input, the initial current is started after the lapse of the pre-flow set time.
