Frequently Asked Questions

What's the difference between a single-stage and a two-stage fuel gas regulator?
A single-stage regulator reduces cylinder pressure to working pressure in one step. Its outlet pressure drifts as cylinder pressure drops, so you may need to readjust it periodically during a job. A two-stage regulator is essentially two single-stage regulators in series: the first stage pre-reduces to an intermediate pressure, and the second stage delivers a nearly constant working pressure regardless of how much gas remains in the cylinder. Two-stage regulators are preferred for precision work and long welding runs.
What working pressure should I set on my fuel gas regulator for acetylene cutting?
Acetylene should never be used at pressures exceeding 15 psig — above that, dissolved acetylene can become unstable and decompose explosively. For most hand-cutting and welding work with acetylene, working pressures run 1–15 psig depending on tip size. Consult the tip manufacturer's chart for the exact oxygen-to-fuel pressure settings for your material thickness.
Are fuel gas regulator connections interchangeable with oxygen regulator connections?
No — they are intentionally non-interchangeable. Fuel gas hose connections have left-hand threads and a groove cut into the swivel nut, while oxygen connections use right-hand threads with a plain nut. The Compressed Gas Association (CGA) specifies distinct inlet connections for each gas so a regulator designed for one gas cannot be accidentally installed on the wrong cylinder.
Can I use a propane or natural gas regulator in place of an acetylene regulator?
No. Regulators are calibrated and approved for specific gas types. Propane and natural gas operate at different pressures and have different CGA inlet fittings than acetylene. Using an acetylene regulator on propane (or vice versa) is unsafe and may not seal properly. Always match the regulator to the fuel gas type listed on the product.
How do I safely open the cylinder valve when attaching a fuel gas regulator?
First back out the adjusting screw until it turns freely (counterclockwise) so the regulator valve is closed. Then stand to one side — not directly in front — of the regulator and open the cylinder valve very slowly to avoid a high-pressure gas surge into the regulator body. Opening it too fast can damage the regulator seat and create a safety hazard.
Do I need a flashback arrestor in addition to the regulator?
Yes, it is strongly recommended. A flashback arrestor (or hydraulic back-pressure valve) sits between the regulator and the hose or torch and stops a flashback — the burning of the flame back into the gas lines — before it reaches the regulator or cylinder. Failing to purge hose lines before lighting the torch and overheating the tip are the two most common causes of flashback.
