Can a propane torch use MAPP gas?
Yes
, MAPP gas works well on a propane torch nozzle, but the flame will be hotter than a propane flame. MAPP is better for soldering copper pipe, but too hot for many smaller copper items. It is also better for brazing and silver solder.
How hot is a propane torch?
Flame temperature
An air-fed torch’s maximum temperature is
around 2,000 °C (3,600 °F)
. However, a typical primary flame will only achieve 1,100 °C (2,000 °F) to 1,250 °C (2,250 °F). Oxygen-fed torches can be much hotter at up to 2,550 °C (4,600 °F).
