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.
