Welding regulators are used to control and regulate the flow of high-pressure gases in a cylinder. Because various types of metals yield different rates of flow, finding the right welding regulator is necessary for control. Shop for medium-duty, heavy-duty, purging, flow gauge regulator capacities for argon, hydrogen, nitrogen, oxygen and many other gases.
All compressed gases are dangerous, some more than others, so the correctly choosing Welding Gas Regulators is essential.
Gas Regulators vary in construction, depending on the gas they’re intended for. Probably the most obvious difference is the screw threads. Regulators for combustible gases (Acetylene, Propane, Propylene etc), usually have Left Hand Threads. The left hand thread is indicated by little cuts in the flats of the Hexagon.
Regulators for non combustible gases (Oxygen, Argon, Co2 etc), usually have Right hand Threads and as such do not have the cuts on the Hexagon.
Another important difference can be the material used to manufacture internal components.
For example, internal Acetylene Regulator components are manufactured from different material to Propane Regulators. It’s therefore important that the correct regulator is used as failure to do so can be extremely dangerous.
In the example outlined above, Propane will corrode the internal components of an Acetylene Regulator, inevitably leading to failure and leaking!
So when choosing welding gas regulators, ALWAYS select the correct regulator for the gas!
