Pipeline-free handheld tool for controlling gas combustion to form cylindrical flame for heating and welding, also known as Palm flame gun (butane is generally used for gas)

II. Structure

Handheld flame gun is divided into two main structures: gas storage chamber and surge chamber. Medium and high-grade products also have ignition structure.

Gas storage room: Also famous box, with gas inside, the composition is generally butane, which is a tool surge chamber structural transportation of gas.

Surge chamber: this structure is the main structure of Palm flame 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 and changing flow.

III. Working principle

Carry out pressure regulating and flow changing on the gas and spray out the muzzle and ignite it to form a high-temperature cylindrical flame for heating and welding and other work.

IV, gas box separation type

In terms of structure, there are two types of palm flame gun, one is air box integrated palm flame gun, and the other is air box separated flame gun heads.

1) air box integrated handheld flame gun: easy to carry, generally smaller in size and lighter in weight than the separate type.

2) gas box separated handheld flame gun head: card-mounted cylinder required, the weight and volume are large, but the gas storage capacity is large, and the continuous use time is longer.

V. Features

Compared with a welding blow lamp and other tools that require pipeline gas transmission, portable flame gun has the advantages of air box integration and wireless portability, but it is limited to the factors that portable flame gun rely on oxygen combustion in the air and gas pressure, commonly used portable flame gun flame temperature generally, it will not exceed 1400 degrees.

Windproof lighter it can be said that it is the predecessor of portable flame gun. Medium and high-end portable flame gun has made innovations and expansion in the following points, which has improved its use value, expanded its use, and is competent for more demanding working environments.

1. Gas filtering structure: reduce the probability of blockage, ensure the use performance of tools and improve the service life.

2. Pressure regulating structure: Optimize and control the gas flow, with higher flame size and temperature.

3. Heat insulation structure: reduce heat conduction effect and ensure the stability of pressure regulating structure and gas flow.
