Oxy Acetylene Cutting and Safety Quiz

What is the most basic form of welding that every welder needs to know?

• MIG welding

• TIG welding

• Oxy acetylene cutting

• Stick welding

Why is it important to open the cylinders slowly when using oxy acetylene?

• To avoid damaging the regulators

• To prevent gas leaks

• To reduce the risk of fire

• To ensure proper mixing of gases

What type of lens should be used when using oxy acetylene for cutting or welding?

• Clear lens

• Shade 3 lens

• Shade 8 lens

• Shade 5 lens

What is the purpose of preheating the material before oxy acetylene cutting?

• To create a neutral flame

• To make the material glow red

• To soften the material

• To reduce the risk of fire

Why is it important to keep the neutral flame cones about an eighth of an inch off the material while cutting?

• To avoid damaging the torch tip

• To prevent overheating

• To reduce gas consumption

• To create a cleaner cut

What is the recommended pressure for acetylene and oxygen when using a single lot 1-0 tip for cutting?

• 15-20 psi acetylene, 50-55 psi oxygen

• 3-5 psi acetylene, 20-25 psi oxygen

• 10-15 psi acetylene, 40-45 psi oxygen

What should be done after completing the oxy acetylene cut on a material?

• Close the oxygen valve first, then the acetylene valve

• Close the acetylene valve first, then the oxygen valve

• Close both valves simultaneously

• Close the oxygen valve first, then the acetylene valve, and then the torch valve

Why is it important to be aware of the surroundings while oxy acetylene cutting?

• To ensure proper mixing of gases

• To prevent overheating of the material

• To prevent accidents with hoses or falling material

• To avoid damaging the torch tip
