Which of the following types of flames is the correct one for heating and cutting with the oxyacetylene rig?

Carburizing flame
Neutral flame
Oxidizing flame
Reducing flame

The correct answer is: Neutral flame

The correct type of flame for heating and cutting with the oxyacetylene rig is the neutral flame. A neutral flame has an equal amount of oxygen and acetylene, resulting in a clean and efficient burn. Carburizing flame has excess acetylene, oxidizing flame has excess oxygen, and reducing flame has excess fuel gas, which are not suitable for heating and cutting metals efficiently.
