Regulators reduce high-pressure gas from a cylinder down to the lower pressure that lets you control the flame. That affects both the quality of the work and your personal safety during torch use.
What Are the Safety Tips for Compressed Gas Regulators?
Handle regulators clean, matched to the gas, and carefully inspected.
- Make certain your hands and gloves are free of oil, grease, or other hydrocarbons when handling regulators, since oil and grease exposed to high pressure can rapidly heat up and cause a regulator to explode
- Use the proper regulator for the gas you are using, because a regulator made for acetylene is not the same as one for a different fuel gas such as propane or natural gas
- Thoroughly inspect regulators for damage before use, including deep scratches or nicks in the inlet fittings, damaged threads, broken or missing parts on pressure gauges, and bent or damaged pressure-adjusting screws
- Before connecting a regulator, make sure the cylinder valve is free of foreign matter by opening it slightly and then closing it immediately, and only open cylinder valves while standing to one side of the outlet, never in front of it
- Attach the regulator to the cylinder and tighten with a non-adjustable wrench or spanner 10 to 12 inches long, taking care not to overtighten the inlet connectors, and remember that acetylene and other fuel-gas regulators use reverse-thread fittings to prevent accidental attachment to an oxygen cylinder
- Turn the adjusting screw on each regulator counter-clockwise until it begins to feel loose, which prevents gas from flowing through the regulator when the cylinder valve is opened
