WARNING
Review the safety precautions in Section 1.
If the power supply cord has a plug or is not permanently connected to power, be sure the power to the outlet is
disconnected when inserting the plug into the outlet.
Disconnect primary power at the source before assembling or disassembling power supply, torch parts, or torch
and leads assemblies, or adding coolant.
It is not enough to simply move the ON/OFF switch on the unit to OFF position when cuing operations have
been completed. Always open the power supply disconnect switch ve minutes after the last cut is made.
NOTE
Prior to starting the system determine the process to be used. The process is determined by the type and thickness
of the metal to be cut. Select and install the required consumables, connect the required gasses to the system.
