Relating to or using a combination of oxygen and acetylene, often used in welding and cutting processes.
The oxyacetylene torch is essential for metalworking tasks.
Oxyacetylene → It is formed from "oxy-" (from Greek "oxys", meaning sharp or acid) and "acetylene" (from the chemical name for a hydrocarbon compound, which is derived from "acetic" (from Latin "aceticus", meaning sour) and "ethylen" (from Greek "aithēr", meaning ether or vapor)). The term refers to a type of gas welding that uses a flame produced by burning a mixture of oxygen and acetylene gas.
Think of 'sharp' or 'acid' ('oxy-') combined with a gas used in welding ('acetylene') to remember that oxyacetylene refers to a welding process that uses a sharp flame.
