Acetylene gas welding uses acetylene mixed with oxygen to produce a high-temperature flame for cutting and joining metals. Specialty gases, such as argon, helium, and carbon dioxide, are often used in welding for shielding, purging, or enhancing arc stability. These gases ensure precision, efficiency, and safety in various welding applications.

Acetylene Gas Welding and Specialty Gases Specifications:
