What You Need to Know About Welding Torches
The welding torch is an instrument made up of a tube which receives oxygen and fuel gas from one end and throws a flame from the other end.
We remember what we have already exposed in this article on the parts of a torch consists of a body with two inlet valves, a mixer, and an outlet nozzle. It is used to join objects of different materials through heat firmly.
Function and Uses of the Soldering Torch
The purpose of the torch is to mix and control the flow of gases that are necessary to produce a flame. When the gases are dosed and combined, the appropriate fire is obtained to carry out the welding.
The use given to the torch is to join, cut and heat different metal parts.
Types of Welding Torches
Welding torches are classified into two categories: the injector and the mixer.
There is a specific advantage of the mixing torch over the injector type, as the former adjusts more quickly and is less prone to flame reversal.
How Should the Welding Torch be Used?
First: Connect the torch with a flexible hose to the gas cylinder regulator. You must make sure that all connections are properly closed to prevent fluid leaks.
Second: Open the cylinder valve slowly. Then open the regulating valve and torch valve so that sufficient gas flow is allowed to ignite the flame.
It is essential that all its elements, gas bottle, hose, and torch, comply with the appropriate safety measures. You must always use this tool correctly. You should always turn it off when not in use and should be kept out of reach of all heat sources. Check that the hoses are not dry or broken.
