detection
Outputs when the current is detected
continuously for 16 ms after the welding start
is pre-flown. After the output, stops outputting
if the current is not detected continuously for
48 ms. Repeats this until the output is
stopped when the wire stick prevention
voltage ends.

detection
(1) Outputs when the arc start is not detected
for 1.5 seconds after the welding start is
pre-flown.
(2) After the arc start is detected within 1.5
seconds after the welding start is
pre-flown, outputs when the arc start is
not detected for 0.6 seconds.
