A red welding hose indicates the hose carries which gas?

Explanation:
Color coding is used for gas hoses to identify the gas and prevent dangerous misconnections. In welding setups, a red hose signals acetylene, the fuel gas used with the torch. Oxygen hoses are typically green, so mixing the two can create a hazardous situation. Hydrogen and nitrogen use different color codes, so a red hose isn’t used for them in standard equipment. So, the red welding hose indicates acetylene.
