Signal
1. The signal is output when the current
is detected continuously for 16 ms
after the gas pre-flow upon receiving
the arc start signal.
2. If the current is not detected for 48 ms
or more continuously after the signal is
output, the signal stops being output.
3. (1) and (2) are repeated.
The signal stops being output at the same
time as the wire stick prevention voltage
ends.
1. The signal is output when the arc start
is not detected for 1.5 seconds after
the gas pre-flow upon receiving the
arc start signal.
2. After the arc occurrence is detected
within 1.5 seconds, the signal is output
when the arc occurrence is not
detected for 0.6 seconds or more con-
tinuously.
3. After the arc failure is detected, the
states described in (1) and (2) are self-
maintained until the start command of
welding source is released.
4. The signal is output also when an
error occurs in the welder.
Common for detection line
Sends the monitoring signal of the output
current.
