How can welding hoses be visually identified?

Welding hoses are color-coded to ensure safety and prevent mix-ups between the gases they carry. The correct identification is established as follows: the oxygen hose is typically green, while the acetylene hose is red. This distinct color-coding aids in the immediate visual identification of the hoses, which is crucial in preventing dangerous accidents that can arise from using the wrong gas during welding operations.

Additionally, the established color scheme is a standard that is widely recognized in the industry, helping workers identify each hose quickly and accurately without needing to read labels or inspect the contents. This is especially important in high-pressure situations where time and clarity are essential for safe operation.
