WARNING: 

  • If a mistake is made in the piping, it may cause flashback on ignition.
  • Always set the gas supply pressures at the specified values.
  • Never use a broken regulator. This may result in gas leaks.
  • If nitrous oxide is used, use the dedicated pressure regulator.

 

• Wipe any dust adhering to the outlet of the cylinder.

• To install these pressure regulators on the cylinders. If the screw for mounting the regulator on the cylinder appears ready to break, replace the cylinder without attempting to mount the regulator.

• Open the cylinder main valve gently after closing the stopcock and turning the secondary pressure control handle sufficiently counterclockwise.
• Turn the secondary pressure control handle clockwise and set the secondary pressure to the following values

  Acetylene: 0.09MPa

  Nitrous oxide: 0.35MPa

• Apply soapy water or leak detection fluid (optional) to each of the connecting joints to check for leaks. Due care should be taken to detect and eliminate any leaking at the cylinder cock.
