Components

The main components of the plasma arc cutting system are discussed throughout this section.

A plasma power source is hooked up to an aluminum box for grounding. The plasma power source is a rectangular shaped box with dials on the frog and slots for cables to be plugged in.

Power source, this will provide the direct current to produce the arc and the gas or compressed air will also flow through the power source.
