OPERATION
4.01 Introduction
This Section provides a description of the Master Power
Supply operating controls and procedures. Identification
of the Front and Rear Panel Controls is followed by oper-
ating procedures.
4.02 Functional Overview
The system is a high performance 50 to 150 amp plasma
cutting system which can cut most metals from gauge
thickness up to two inches. With a quick change of torch
parts, power supply can also be used for plasma arc goug-
ing. In its simplest form, a system consists of one Master
Power Supply, one Arc Starter Box and one Maximizer
300 Liquid Cooled Torch and leads connected.
With the addition of a Slave Power Supply or a second
Master Power Supply the system becomes a 100 to 300
amp plasma cutting system which can cut most metals
from gauge thickness up to three inches.
