The 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, Mechanical Gas Savers can be used with natural gas, propane, hydrogen, 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 WDW-100. The WDW-100 is used with MAPP/Propylene. The model WDW -101 is used with Acetylene. The model WDW-103 is setup to run with Natural Gas, Propane or hydrogen below 4 psi. (NOTE: When using hydrogen a separate natural gas or propane feed is needed for the pilot.) The WDW-104 is used with propane or Natural gas at 4 psi or more. All 4 models come with adjustable pilots.
