Oxyfuel Gas Cutting Torches: Types and Characteristics

What are the different types of oxyfuel gas cutting torches?

There are two types of oxyfuel gas cutting torches: the positive-pressure torch and the injector torch.

The Positive-Pressure Torch

The positive-pressure torch operates by maintaining a steady pressure from the fuel source and mixing oxygen with it under this constant pressure. This type of torch is suitable for applications where a controlled and consistent flow of fuel gas and oxygen is required. Characteristics: - Uses both oxygen and fuel gas at positive pressure - Provides a stable and steady flame - Ideal for cutting thick materials

The Injector Torch

The injector torch works differently from the positive-pressure torch. It utilizes high-pressure oxygen to draw fuel gas into the torch, eliminating the need for the fuel source to be under high pressure. This type of torch is commonly used for tasks that require precision and speed. Characteristics: - Uses oxygen at positive pressure while drawing fuel gas in with higher oxygen pressure - Offers precise and efficient cutting - Suitable for intricate cutting tasks In conclusion, the choice between the positive-pressure torch and the injector torch depends on the specific requirements of the cutting application. Both torch types have their own advantages and are used in various industries for cutting, welding, and metal fabrication processes.
