The REGULA EWR can do more than just saving gas.
The gas flow is regulated automatically and synchronously with the welding current during the entire welding process. "More current - more Gas / Less current - less Gas"
Extremely fast Gas valve that opens and closes even at very short welding stops
Pulsed Gas allows more reduction of Gas flow depending on the possibility for trimming "programming" with unchanged high Gas protection
Elimination of gas puffs as a side effect of the above methods
The EWR can show problems with incoming gas in the line before the EWR.

Better seam quality, especially during arc start period
The EWR work with 2-6 bar incoming pressure - so it can be used in some cases directly on the gas supply system (pipe system) without a pressure reducer (not on bottle).
The EWR can show leakage in the system by using the display on the EWR PRO
The EWR can show problems in outgoing gas supply after the EWR (for example : drilled gas hose to the wire feeder)
