Gas combustion principle:
1.Mapp gas brazing torch mainly use MAPP gas as fuel. When MAPP gas is sprayed out from the nozzle of the brazing torch, it mixes with oxygen in the surrounding air.
2.The mixed gas is ignited by an ignition device (such as an automatic igniter or a manual ignition device) to cause a combustion reaction. The combustion process is a violent oxidation reaction that releases a large amount of heat energy. Its chemical equation (taking methylacetylene as an example) is roughly:
In this reaction process, methylacetylene reacts with oxygen to produce carbon dioxide and water, and releases heat, which increases the flame temperature.
Heat conduction and welding process Tel：+86-592-5803997
The high-temperature flame generated by the combustion acts on the surface of the metal material being welded. The heat of the flame is transferred to the metal by heat conduction, causing the temperature of the metal surface to rise above the melting point.
During the brazing process, when the metal surface reaches the appropriate temperature, the brazing material (such as tin-lead alloy, etc.) is placed on the welding site. The brazing material melts at high temperature and fills the gap in the metal joint by capillary action. When the brazing material cools and solidifies, the two metal parts are connected together, completing the welding process. For example, in the welding of copper pipes for refrigeration equipment, the flame of the mapp torch kit heats the joint of the copper pipe, causing the brazing material to melt and fill the joint gap, thereby achieving the connection of the copper pipe.

how to use map pro gas torch
Caution:
Avoid inverted use:during use, avoid using the gas cylinder upside down to avoid accidents.
Storage and preservation: When not in use, it should be stored in a dry, ventilated, cool place, away from direct sunlight and high temperature environment. At the same time, the integrity of the gas cylinder and welding gun head should be checked regularly to ensure the safety and reliability of the equipment.
