13.4.6 Control timing

Gas pre-flows/gas post-flows
The timing for weld start and gas pre-flows/gas post-flows normally corresponds to the timing described if
no end crater is set.
However, if gas rinsing was activated before the weld start and the weld start is activated without
deactivating gas rinsing, the pre-flow period is omitted and the voltage is immediately present at the output.
In the opposite case, regardless of whether gas rinsing is switched between ON/OFF after the welding
process is complete, there is a mandatory post-flow period during which gas rinsing cannot be stopped.
Pre-flow time and post-flow time can be set to 0.
Sequence at weld start and at wire feed/wire retract/weld detection
The weld sequence determined by ON/OFF switching of the welding start mode is shown in the following
diagram.
The welding conditions (welding mode, welding current, etc.) for starting the welding process must be set at
least 30 ms before the welding start is activated. If the welding condition is changed at the same time as
the welding start is activated, changes to the welding conditions may not be applied properly at the time of
the welding start.
No wire feed, wire retract, or weld detection processes are allowed during the period between the time the
weld start is activated until the inverter (voltage output) is turned off. If the wire feed or wire retract mode is
activated before the weld start is activated, weld start is not allowed. If weld start is activated during a weld
detection process, the weld start has priority and the weld detection process is stopped.
The welding conditions for starting the welding process must be set at least 30 ms before the welding start
is activated.
