A __ mixes oxygen and acetylene?

Explanation:
Mixing oxygen and acetylene happens in the welding torch. The torch has separate valves for each gas and a mixing zone at the tip. When you open both valves, the gases meet in the torch and mix just before combustion, letting you control flame temperature and size by adjusting the gas flows. This blending is essential for oxy-fuel welding, where the right flame is needed to heat the metal properly. A striker lights the gas flow but does not mix the gases. A flash arrestor is a safety device to prevent backflow along the hoses, not a mixer. The other option with a number isn’t a device used to mix gases. So the welding torch is the correct choice because it’s designed to blend the gases into a controlled flame for welding.
