Q. What is a brazing torch?

Answer

A brazing torch is a metal cutting or metal welding torch, which is also called an oxy-acetylene torch. Brazing is a technique similar to that of soldering, but it differs in the aspect that it is done at a much higher temperature. Also, in the soldering process, a solder made up of 60% tin and 40% lead, which has a low melting point is used to deposit on joints to be soldered. Here, in brazing, we typically use a brass rod. The flame used is either through oxy-acetylene combustion or could be modified propane, also called Mapp Gas. The brazing technique or brazing is done in order to join combinations of copper and brass. A brazing torch is used by metal workers, and more specifically artisans dealing with the crafting of copper or brass products like jugs, kettles, etc. Brazing torches are regularly found on HVAC engineering sites to weld copper tubes of heat exchangers.
