INTRODUCTION
The Powermax350 plasma cutting system uses a chopper power supply to cut mild steel, stainless
steel, aluminum and other metals. Cylinder air or shop air is used as the plasma gas. Air used for
plasma cutting must be clean, dry and oil-free.
This instruction manual provides information for the user to set up and operate the system and perform
limited maintenance on the torch and power supply. This manual also provides a detailed list of safety
practices so that the system can be safely operated and maintained. READ THE SAFETY SECTION
(Section 1) FIRST!
The Powermax350 service manual provides higher-level troubleshooting and a more complete parts
list.
