Answer:
Air -acetylene
Explanation:
The heat and temperature produced by an acetylene flame depend upon the amount of oxygen used to burn it. Air-acetylene produces a flame temperature of around 4000° F (2200° C). This is hot enough to solder aluminum work glass, repair radiators and braze plumbing fixtures. It is not hot enough to weld steel.
It can be used for Air Acetylene welding.
