3 easy step to install

After a few minutes installation, the Regula EWR is ready to save gas cost for you. The EWR can e.g. be fixed on the power source with double sided tape. Cut the gas hose and connect to the EWR. Shunt shall be mounted on the return or positive conductor cable , and the EWR to be connected to 100V-230V power supply.

Regula EWR (Electronic Welding Regulator) automatically adjusts the gas flow syncronized to the actual welding current. At higher welding current, the EWR gives more gas flow and at a lower welding current it gives a lower gas flow. More and more users can tell that Regula EWR reduces gas consumption by up to:

60%

After an initial adjustment EWR is self-regulating and always gives the optimal gas flow syncronized to the welding current during the entire welding process. With Regula EWR, the need for gas supply is less at 150 A than at 200A, but the reduced consumption is still sufficient for an excellent weld.

The welder can with EWR fully concentrate on the welding and he can feel safe that the gas coverage always follows the actual welding current. This is especially important when welding with welding torches equipped with program selector or remote control.

The old inefficient gas reduction method.

The old method to manually set pressure and flow on a reduction valve, often becomes a permanent setting. The setting will often not be changed during the entire welding process, even if the welding current changes. The welder will be forced also by the old method, to always make the gas flow so high that it is enough to provide sufficient gas coverage also for the maximum welding current. The old method is a big waste of gas and a bad gas utilization that only gas suppliers can enjoy.

The patented Regula EWR PRO method

EWR method means an entirely new way of thinking. On one hand, the ”gas-peak” disappears, but also that the right amount of gas always flows out through the welding torch gas nozzle. From a shunt placed on return or positive conductor cable, the actual welding current is transferred by a shunt that sends a signal to the EWR electronics and to the software that controls a frequency controlled gas valve instantaneous. The valve works after a patented technology and is extremely fast. It reacts automatically on very small changes in the welding current and the gas flow is totally shut down, even at very short welding interruptions.
