The EWR2 system uses a patented functional principle, using an overspeed solenoid valve to adjust the gas flow in real time and keep it synchronized with the welding current changes. Changes in external factors such as ambient temperature changes, shielding gas input and back pressure from the welding gun cable can be safely compensated. In this way, EWR 2 guarantees the potential for gas savings and can control the gas flow more accurately than traditional gas control systems.
Internationally patented product, intelligently adjusts the gas flow according to the current size.
Gas leak alarm reduces gas waste.
It can also collect welding current, shielding gas pressure and flow data, and remotely monitor the working status via Ethernet, and can be connected to the Mass system through secondary development.
