The correct answer is 'hielding or cooling gas'.
Explicación
## Step 1The problem is about the components of a heavy-duty plasma cutting system. These systems typically use a gas cylinder that contains the cutting gas. The question asks for the type of gas that is contained in the second cylinder.## Step 2The options provided are acetylene, water vapor, shielding or cooling gas, and a mixture of cutting gas and shielding gas.## Step 3Acetylene is a type of gas used in welding and cutting processes, but it is not typically used as a shielding or cooling gas.## Step 4Water vapor is not a gas used in plasma cutting systems.## Step 5Shielding or cooling gas is used in plasma cutting systems to protect the metal from the intense heat of the plasma arc and to cool the metal.## Step 6A mixture of cutting gas and shielding gas is not typically used in plasma cutting systems.
