What type of flame is ideal for most welding and cutting applications with an oxygen-acetylene torch?

• Oxidizing flame

• Carburizing flame

• Neutral flame

Why is it important to check for gas leaks when setting up an oxygen-acetylene torch?

• To conserve gas

• To prevent fires and explosions

• To increase welding speed

Which gas cylinder is typically color-coded in green for an oxygen-acetylene torch setup?

• Acetylene

• Oxygen

• Argon

What safety equipment is essential when using an oxygen-acetylene torch?

• A welding jacket and a baseball cap

• Safety glasses and open-toed shoes

• Safety glasses with shade 5 lenses and a welding jacket

In what order should you shut down an oxygen-acetylene torch after use?

• Close the oxygen valve first, then the acetylene valve

• Close the acetylene valve first, then the oxygen valve

• It doesn't matter; you can close either valve first

What is the purpose of purging the hoses before lighting the torch?

• To clean the hoses

• To preheat the hoses

• To remove contaminants and prevent explosions

Which gas in an oxygen-acetylene torch supports combustion?

• Oxygen

• Acetylene

• Argon

What should you do if you detect a gas leak during setup or operation of an oxygen-acetylene torch?

• Ignore it; it's usually not a problem

• Continue working but report it later

• Shut off the gas and repair the connection immediately

What is the correct sequence for lighting the torch when setting up an oxygen-acetylene flame?

• Oxygen, then acetylene

• Acetylene, then oxygen

• Oxygen and acetylene simultaneously

When storing an oxygen-acetylene torch, what safety precautions should be taken?

• Store the torch with the valves open

• Store the torch in a closed, unventilated area

• Store the torch in a well-ventilated, secure area with the valves closed
