アフターフロー設定時間
When the head is moved from start point, turn off the H-READY signal.
When the head is moved from mid-point to weld point (initial current), turn on the GAS signal of option input/output connector (or the PURGE signal
of option input/output connector) to turn on the solenoid valve for (argon) gas. When the H-END signal is turned on, turn off the GAS signal (or
the PURGE signal) to turn off the solenoid valve for gas.
After the head is moved to weld-point (initial current), turn on the initial current start signal H-ST1.
