  If shield gas is not supplied when you press the torch switch on your Daihen Wire Feeders, the issue might stem from a closed discharge valve on the gas cylinder. Make sure to open the valve. Alternatively, there might be insufficient gas pressure in the cylinder, so check the gas pressure. A faulty gas solenoid valve could also be the culprit; inspect it and replace it if necessary.
