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. However, they are limited to portable torches relying on factors such as oxygen combustion in the air and gas pressure. The flame temperature of the flame torch generally does not exceed 1400 degrees.

The windproof lighter can be said to be the predecessor of the portable torch. The mid-to-high-end portable torch has been innovatively expanded in the following points to increase its use value, expand its use, and be competent in more demanding working environments.

1. Air filter structure: reduce the probability of blockage, ensure the performance of the tool, and increase the life.

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

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