7.2.3 Decreasing the gas flow rate
1
To reduce the gas flow rate, press the - arrow button
2
Any key press will reduce the gas flow rate by 1 l/min.
3
The decrease is indicated by one or more green LEDs lighting up below the
orange LED
4
To save the set value, wait for 5 seconds, before interrupting the power
supply or making further settings.
8 Adjusting the outlet stagnation pressure
8.1 Setting the outlet stagnation pressure
The EWR gas monitoring system is pre-programmed to refill the gas hoses. If no
welding is taking place, the pressure can be adjusted in accordance with the
hose length from the solenoid valve on the welding unit prior to the welding
process.
