SoldBy the cylinder

Acetylene is the fuel gas of an oxy-acetylene torch set. Burned with oxygen at the torch, it produces a hot, concentrated flame that quickly brings a copper joint up to brazing temperature. Refrigeration technicians use it to assemble and repair refrigerant lines, especially the large diameters on central and commercial systems.

The rules specific to acetylene

Acetylene is not like other gases. The safety rule sets its working pressure at a maximum of 15 psi (103 kPa) gauge pressure: above that, it becomes unstable. The cylinder is stored and used upright, valve end up. Both rules appear in OSHA standard 1910.253 on oxygen-fuel gas welding and cutting; OSHA is the U.S. federal occupational safety and health agency.

Good safety practices

  • Set the acetylene regulator without ever going above 15 psi.
  • Fit the torch set with check valves and flashback arrestors.
  • Leak-test fittings with soapy water, never with a flame.
  • Store acetylene away from oxygen cylinders, with cylinders secured upright.
  • Work in a ventilated area, away from any combustible material; remove the regulator and put the protective cap back on before moving the cylinder.

The safety data sheet is supplied with the cylinder by its manufacturer. The cylinder size is confirmed with the quote.

01 · What it is for

The fuel for the oxy-acetylene torch

Burned with oxygen, acetylene gives the hot, concentrated flame that quickly brings a copper joint to brazing temperature.

  • Brazing copper refrigerant lines on heat pumps and air conditioners
  • Large-diameter joints on central and commercial systems
  • Brazing brass fittings and components, with flux
  • Line repairs in the field
Concentrated flameHeat goes onto the joint, which keeps heating time short.
15 psi maximumAcetylene is never used above 15 psi (103 kPa) gauge pressure.
Always uprightThe cylinder is stored and used valve end up.

03 · Before installing

What to know before installing

  • Never set the working pressure above 15 psi (103 kPa).
  • Store and use the cylinder upright, valve end up, firmly secured.
  • Fit the rig with check valves and flashback arrestors, and check connections with soapy water.
  • Work in a ventilated area, away from combustible materials.

05 · Questions

Frequently asked questions

Why not go above 15 psi?

Above that pressure acetylene becomes unstable. The safety rule is clear: it is never used above 15 psi (103 kPa) gauge pressure.

Why keep the cylinder upright?

Acetylene cylinders are stored valve end up. One that has been lying down must not be used as is; follow the maker’s instructions before returning it to service.

What else is needed besides the cylinder?

An acetylene regulator, hoses, a torch, check valves and flashback arrestors, plus an oxygen cylinder.

Do you do the brazing for customers?

Yes. Our technicians braze the refrigerant lines on every installation in Greater Montréal.
