a.  DELAY START SET 

One welding condition is determined via 

DELAY START SET

, a value corresponding to chatter 

prevention time, after a start signal is input.  The 

DELAY START SET

 period can be set in a 

range from 1 to 20ms, in unit of 1ms.

In Figure A above, the schedule signals 1 and 8 are ON.  Therefore, welding is performed using 
schedule number. 9.  In Figure B above, only schedule signal 8 is ON.  As a result, welding is 
performed using schedule number 8.  Schedule signals 16 and 32 are invalid because they are 
OFF when the schedule is determined.
