The plasma power supply automatically adjusts for correct operation at the current
input voltage. You do not have to change or rewire components. But there are tasks you must
do for correct installation.
For
correct installation of the plasma cutting system:
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.
Note:
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.
