* Fuel type: Different types of Mapp gas have different burning characteristics and temperatures.
* Oxygen pressure: Higher oxygen pressure leads to a hotter flame.
* Mixing ratio of fuel and oxygen: The ideal ratio for maximum temperature varies with the fuel.
* Burner design: The type of burner and its design can influence the flame temperature.
Generally, an oxy-mapp gas flame can reach temperatures between 3,500°F (1,927°C) and 4,000°F (2,204°C).
Note: This is a general range. For specific temperature data, it's best to consult the manufacturer's specifications for the specific Mapp gas and equipment you are using.
