The EL Gas Savers Series uses solenoid valves in conjunction with a foot pedal to control the flow of gases. When the foot pedal is actuated the solenoid valves go to the on position. The on position will vary depending on the model in question. When the foot pedal is actuated a second time the solenoid valves go to the off position. The EL Gas Saver Series can be used with natural gas, propane, methane, butane, mixed gases, hydrogen, air, or oxygen.
The EL Gas Savers are available with one, two, three, or four solenoid valves. By specifying the delay option, the system then will be fitted with a timer that will delay the closing of the gas solenoid valve. This will allow the other valves to shut off before the delayed valve. The air purge option allows one of the solenoid valves to control an air line that will be used only for purging the system. When the Gas Saver is shut off, it will close the other valves and then open the air valve for a predetermined time between one and ten seconds. The EL Gas Saver Series is not to be used with a premix burner without either the delay or purge options. These options allow the Gas Saver to run safely with a premix burner.
The EL Gas Savers are also available in the standard 1/4" valve or the Hi-Capacity 1/2" valve. The connections available are hose adapters, welding hose adapters, or JIC adapters.
The Carlisle Mechanical Gas Savers allow the operator to hang a torch from the arm, shutting off the gas flow to the torch and therefore saving gas when the torch is not needed. Models are available with a pilot flame on the unit so that the torch can easily be relit when needed. Depending on the model selected, Carlisle Mechanical Gas Savers can be used with natural gas, propane, butane, methane, acetylene, or mixed gases and oxygen, air, or water.
The Mechanical Gas Savers are available in four different models. The first model is the W-101-E. The W-101-E is used with Acetylene. The model W-102-EI is used for inert arc welding operations. This model allows for positive shutoff of both gas and water and is not available with a standing pilot. The model W-103-ELP is specifically setup to run with Natural Gas. The W-104-P is used with propane at 4psi or more. This unit uses special seals that are designed for use with propane gas.
