Precautions for using butane torch

working principle

The gas is compressed and transformed, sprayed out and ignited to form a high-temperature cylindrical flame. The torch is divided into two main structures: a gas storage chamber (gas tank) and a surge chamber. The medium and high-end products also have an ignition structure.

The gas storage chamber is also known as the gas tank. It contains gas, and the composition is generally butane (high concentration causes paralysis and dizziness).

The surge chamber is the main structure of the torch gun. The gas is sprayed out of the muzzle through a series of steps, such as receiving gas from the gas storage chamber, and then filtering and regulating the flow.



The torch is a tool for fuse welding, China Factory Butane Flame Gun KLL-9002D surface treatment and local heating of equipment. Generally, ordinary liquefied petroleum gas is used, which is convenient and economical, and also greatly improves work efficiency. The flame gun is safe to use, exquisite in design, and easy to operate. It is an ideal choice for factories, restaurants and other places that use flame spray devices for a long time. Compared with welding torches and other tools that require pipeline transportation of gas, portable torches have the advantages of an integrated gas box and wireless portability. The flame temperature of the gun generally does not exceed 1400 degrees.


1. Check

Listen for a slight air leak and smell for any peculiar smell. Do not use if the smell is strong.

Connect all parts of the spray gun, connect the liquefied gas connector, loosen the valve of the liquefied gas cylinder, and check whether the parts are leaking.

2. Ignition

Open the gas valve first, then loosen the spray gun switch slightly, use the nozzle to directly ignite, and adjust the gas valve of the spray gun to reach the required temperature.

3. Close

First, close the valve of the liquefied gas cylinder. After the flame is turned off, turn off the switch (no residual gas should be left in the pipe), separate the spray gun from the gas pipe, hang it up, and place it in a dry place. Author: A lovely chemistry club in a university Source: bilibili
