what is the temperature of a propane torch
Propane torch Oxygen-fed torches use the high pressure of the stored oxygen to push the oxygen into a common tube with the fuel. An air-only torch will burn at around 1,995 °C (3,623 °F), less if heat loss to the surroundings is taken into account. Oxygen-fed torches can be much hotter at up to 2,820 °C (5,110 °F), depending on the fuel-oxygen ratio. These are the theoretical maximum temperatures, in reality they will always be less due to incomplete combustion, heat loss etc.
