The gas factor for self-configured gas types must be calculated. The gas factor
can be set in the <Gas factor> submenu item. Set the gas factor for the gas
already selected under <3 Gas type>. The gas factor can be calculated using
any gas and any number of gases and then entered. In the case of mixed gases,
the factor should be calculated as follows using factors for the individual gas
components:
82% argon / 18% CO2
Argon = 0.851 / CO2 = 0.809
Total calculation factor:
(Percentage of argon × argon calculation factor) + (percentage of CO2 × CO2
calculation factor)
(0.82 × 0.851) + (0.18 × 0.809) = 0.843

This function is available with firmware version A.1.5.0 and higher and must be
activated once using the service software.
In contrast to the basic flow, the gas volume flow in the pressure regulation
range can be adjusted. An asterisk is not shown on the display if a welding
current signal is not detected. The device then operates in the pressure
regulation range.
If the device switches to gas volume flow regulation, an asterisk appears on
the display. The device then operates with the set basic flow (not with the gas
flow in pressure regulation) and uses this for gas volume flow regulation. The
gas volume flow in the pressure control range can be set between 5 l/min and
30 l/min. This parameter can also be set to <max>. At <max>, the valve in the
device is fully open and does not perform any control.
