When oxy-fuel welding, gases are mixed before exiting the torch in which component?

Explanation:
In oxy-fuel welding, the gases are blended together in a dedicated mixing chamber called the mixer. This is where the fuel gas and oxygen are combined to the correct ratio before they exit the torch and burn. The regulator’s job is simply to reduce cylinder pressure to a safe, workable level, not to mix gases. The valve controls how much gas flows to the torch, again without mixing. The torch head shapes and directs the flame, but the actual blending of the gases happens in the mixer, making it the correct component.
