When switching on Oxy Acetylene Gas Welding, I must first switch on __________.

• Oxygen Gas

• Acetylene Gas

• both Oxygen Gas and Acetylene Gas

• either Oxygen Gas or Acetylene Gas, it does not matter

What is the mixture of Neutral Flame?

• Oxygen only

• Oxygen > Acetylene

• Oxygen < Acetylene

• Oxygen = Acetylene

What is the mixture of Oxidising Flame?

• Oxygen only

• Oxygen > Acetylene

• Oxygen < Acetylene

• Oxygen = Acetylene

What is the mixture of Carburising (Reducing) Flame?

• Oxygen only

• Oxygen > Acetylene

• Oxygen < Acetylene

• Oxygen = Acetylene

What is a Regulator?

• A device to show how much gas is contained in the cylinder.

• A device to show the amount of pressure is currently being used.

• A safety device to regulate (control) amount of gas coming out of the cylinder.

• A safety device to prevent any Gas to flow back into the cylinder
