Mr. Navarro's Chapter 7 Vocab. Exam

A group of thermal cutting processes that severs or removes metal by melting with the heat of an arc between an electrode and the workpiece.

• nozzle tip

• arc cutting

• water table

A gas that has been heated to at least a partially ionized state, enabling it to conduct an electric current.

• water shroud

• nozzle insulator

• arc plasma

Term used to refer to the arc plasma used in welding and cutting processes that produces the high temperature and intense light associated with welding and arc cutting

• electrode setback

• nozzle

• plasma arc

A state of matter that is found in the region of an electrical discharge (arc).

• plasma

• dross

• kerf

Plasma created by an arc that has electrons and + ions whose charges are nearly equal.

• cup

• ionized gas

• standoff distance

Tip often made of copper with an embedded tungsten tip.

• electrode tip

• joules

• plasma arc gouging

Situated between the electrode tip and nozzle tip.

• arc plasma

• nozzle insulator

• plasma arc

The spacing between the electrode tip and the nozzle tip.

• plasma

• ionized gas

• electrode setback

Tip with a cone-shaped constricting orifice on the center that restrict the gas in the presence of the electric current so the plasma can be generated

• pilot arc

• arc cutting

• nozzle tip

Made of ceramic or any other high-temperature-resistant substance and provides control of the shielding gas or water.

• arc plasma

• nozzle/ cup

• water table
