Install and Set Up the Plasma Power Supply
32 811470 Operator Manual Powermax45 SYNC
To operate the plasma power supply at full output and at its rated duty cycle, you must make your
electrical service the correct size. The tables that follow show the maximum rated output for typical
input voltages. The output setting that you use relates to the thickness of the workpiece and the limit
of the input power to the plasma power supply.
In certain applications, such as gouging, stretching the plasma arc is
common. Using the recommended fuse sizes allows for spikes in input
current during this process.
