Why shielding gas offers a huge savings potential
The valve is opened and there it is: the shielding gas for welding. Depending on the requirements of the welding task, the gas pressure and gas quantity are still set with the manometer before starting. Pre-flow time? Rather a little longer. Better safe, than sorry. The same applies to the post-flow time. Whether this lasts a few seconds longer or not does not seem to make much difference. Or maybe it does? The fact is: the shielding gas consumption is usually much too high. With the gas management system EWR 2 you can save money in gas shielded arc welding.
