The device is an electronic gas management system with a closed loop gas system. The shielding gas flow
during the welding process is optimized in terms of gas consumption and process stability, and is regulated
dependent on the welding current. A measurement shunt (F) reads the present welding current, and the
EWR 2/EWR 2 Net (B) regulates the gas flow rate via a characteristic curve that has been set as required.
This allows regulation of the gas pre-flow and post-flow periods and gas savings at the start of the process,
during welding pauses, and at the end of the process. This device consists of a housing with display and
arrow buttons, as well as a status LED. It also has a proportional valve and pressure sensors. The EWR 2 Net
device version has a measurement shunt interface, a CANopen interface, and an Ethernet interface.
