1.3 Use of Your Plasma Cutter 

 

Do not operate the plasma cutter if the torch is wet. Do not immerse the plasma torch. Do not stand 
in water while using this plasma cutter. These components and the plasma cutter must be 
completely dry before attempting to use it. 
-Follow the instructions in this manual. 
-Keep the plasma cutter in the off position when not in use. 
-Connect ground lead as close to the area being cut as possible to ensure a good ground. 
-Do not allow any body part to contact with the material being cut, or to the ground or 
electrode from another plasma cutter or welder. 
-Do not cut if you are in an awkward position. Always have a secure stance while cutting to prevent 
accidents. Wear a safety harness if working above ground. 
-Do not drape cables over or around your body. 
- Wear eye protection (see ANSI Z49.1 safety standard) while cutting to protect your eyes from 
harmful UV and IR rays. 
-Wear proper gloves and protective clothing to prevent your skin from being exposed to hot metals, 
UV and IR rays. 
-Do not overuse or overheat your plasma cutter. Allow proper cooling time between duty cycles. 
-Keep hands and fingers away from moving parts. 
- Do not point the plasma torch at any body part or at anyone else. 
-Always use this plasma cutter in the rated duty cycle to prevent excessive heat and failure. 
 

1.4 Specific Areas of Danger, Caution or Warning 

  Electrical Shock 

 

Plasma cutters can produce a shock that can cause injury or death. Touching 
electrically live parts can cause fatal shocks and severe burns. While cutting, all metal 

components connected to the wire are electrically hot. Poor ground connections are a hazard, so 
secure the ground lead before cutting. 
-Wear dry protective apparel: coat, shirt, gloves and insulated footwear. 
-Insulate yourself from the work piece. Avoid contacting the work piece or ground. 
- Do not attempt to repair or maintain the plasma cutter while the power is on. 
-Inspect all cables and cords for any exposed wire and replace damaged or wore cables 
immediately. 
-Use recommended replacement cables and cords. 
-Always attach the ground clamp to the work piece or worktable as close to the cutting area as 
possible. 
-Do not touch the torch and the ground or grounded work piece at the same time. 

  Fumes and Gases 

 

-Fumes emitted from the plasma cutting process displace clean air and can result in injury 
or death. 

-Do not breathe in fumes emitted by the plasma cutting process. Make sure your breathing air is 
clean and safe. 
-Work only in a well-ventilated area or use a ventilation device to remove plasma cutting fumes from 
the environment where you will be working. 
-Do not plasma cut on coated materials (galvanized, cadmium plated or containing zinc, mercury or 
barium). They will emit harmful fumes that are dangerous to breathe. If necessary, use a ventilator,
