There are three basic flame types: neutral (balanced), excess acetylene (carburizing), and excess oxygen (oxidizing).
Neutral Flame:
Neutural welding flames are commonly used to weld:
In the neutral flame, the temperature at the inner cone tip is approximately 5850ºF (3232ºC), while at the end of the outer sheath or envelope the temperature drops to approximately 2300ºF (1260ºC).
Carburizing Flame:
Oxidizing Flame:
