*1 The time from a SCH No. changeover to the validation of the READY signal varies depending on the setting of the SCH
changeover delay time (Refer to 4. (6).).
After the lapse of the SCH changeover delay time, SCH No. is decided finally and welding data is created. The time required
to create welding data becomes longer in proportion to the set time of First w Second welding. It is about 1 ms at the
minimum weld time: 1 ms and about 340 ms at the maximum weld time: 4 s. From these contents, the time from the end of
SCH signal operation to READY signal ON becomes SCH changeover delay time (1 ~ 200 ms) + Welding data creating time (1
~ 340 ms).

(m) START signal input delay time.”
*3 Operate the PARITY signal until the START signal is input.
The use/no use of the PARITY signal can be set in the “Start parity error ON/OFF” item after displaying the Switch select screen
from the Basic setting screen. Refer to “4. (6) Switch Select Screen.”
