Dissolved Acetylene (C₂H₂) is a high-energy, colorless fuel gas known for delivering the hottest flame used in welding and cutting. Safely stored in acetone-filled cylinders, it provides a stable, clean, and fast-burning heat ideal for oxy-acetylene welding, cutting, brazing, and metal fabrication. It also plays a vital role as a raw material in chemical and plastic production, making it a key gas across modern industries.
