by Staff
One of the most remarkable tool inventions of the 20th century was the plasma cutter. Today, it is becoming increasingly useful in more and more fields of work, as well as being smaller and more affordable. Find out how much do you know about the plasma cutter by taking this quiz.

Why do we use metal components to build industrial and everyday items?

  • because they're both strong and durable
  • because they reflect light
  • because they conduct electricity well

When was the plasma cutter introduced?

  • during World War I
  • during World War II
  • during the Persian Gulf War

What was the breakthrough discovery that led to the invention of the plasma cutter?

  • Atomic particles could be harnessed to form highly compressed gases.
  • Gas could be heated to extreme temperatures and transformed into plasma.
  • Charging a gas with an electric current protected a weld from oxidation.

During the 1960s, what did engineers discover about the cutting properties of a gas that was heated to very high temperatures?

  • When used as a tool, it worked more like a welder than a saw.
  • When used as a tool, it worked more like a cutting saw than a welder.
  • When used as a tool, it can cut and weld simultaneously.

What are the four states of matter in the universe?

  • atomic, nuclear, dark, extrasensory
  • earth, wind, fire, water
  • solid, liquid, gas, plasma

Which state of matter fits the description: It has a fixed volume but no fixed shape?

  • liquid
  • gas
  • plasma

What happens to molecules with the application of heat?

  • They repel each other.
  • They become more tightly bound.
  • They break loose of the bonds that bind them together in their colder state.

In a plasma, where would you find the electrons?

  • separated from the nucleus
  • within the nucleus
  • surrounding the protons

What is another name for the positively charged nuclei?

  • neutrons
  • ions
  • molecules

What happens to rapid-moving electrons when they collide with one another in a plasma state?

  • They break apart.
  • They release enormous energy.
  • They bond incredibly strongly.

What is a good example of plasma on our planet Earth?

  • tsunami
  • earthquake
  • lightning

Can cool plasma cut metals?

  • Sometimes, depending on the cutting tool and the type of metal.
  • Yes, it can.
  • No, it can't.

How small can a plasma cutter be?

  • about the size of a small television
  • small enough to be handheld
  • as small as a pinhead

Which of these gases might be found in a plasma cutter?

  • nitrogen or oxygen
  • hydrogen or helium
  • carbon dioxide or methane

How hot can the plasma be in a plasma cutter?

  • 15,000 degrees Fahrenheit (8,325 degrees Celsius)
  • 30,000 degrees Fahrenheit (16,649 degrees Celsius)

Why do plasma cutters have shielding gas flowing around the cutting area?

  • to maintain the high temperature and to keep the gas from escaping
  • to maintain contact between the metal and the cutter and to control the unpredictable plasma
  • to ensure a constant grasp on the metal and to shield it from UV rays

Why do locksmiths use plasma cutters?

  • to bore holes in safes and vaults when the customer is locked out
  • to cut new house keys when they are lost
  • to cut through padlocks that have become rusty

What has changed financially over the years regarding the purchase of plasma cutters?

  • Prices have fluctuated continually due to supply and demand.
  • They have become more and more expensive.
  • They have become more and more affordable.

What do artists use plasma cutters for?

  • to do precise paper cutting and calligraphy
  • to create airbrush designs
  • to bevel cuts and bore precise holes

What does the plasma cutter have that enables you to measure and cut metal without even touching it.

  • an electronic eye
  • computer numerically controlled (CNC) cutting
  • a heat sensor pad
