Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials.

It is used in oxy-fuel cutting to heat the metal at its ambient temperature. This gas cutting torches use gases like acetylene, propane, propylene and natural gas. The welding torch is a heat source for manual brazing and braze welding and metal forming and welding.
