Auto mode supplying the main welding when the head
supplies the initial current to the main welding position from
the initial current position and reaches the main welding
position in the auto mode (when the initial current time is set
to 0 ms)
*1 H-READY is the READY signal for the head controller.
*2 M-READY is the READY signal for MAWA-300B . (Refer to “05. READY” in “2.(3)-3-2. User output terminals.”
