14.2 PAC Equipment and Setup

Components

The main components of the PAC system are discussed in 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.

A main component is the power source, which will provide the direct current to produce the arc. The gas or compressed air will also flow through the power source.

The next main component is the welding torch. A handheld torch is used for the handheld plasma system and a straight torch for mechanized cutting is used for a mechanized plasma system. Handheld plasma torches have a safety over the trigger. However, for the straight torch everything is controlled by the operating table or mechanism.
