Operating Instructions and Parts Manual
Plasma Cutter
Plasma 275
-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 work table 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, respirator with air supply or
remove the coating from the material in the area to be cut.
-The fumes emitted from some metals when heated are extremely toxic. Refer to
the material safety data sheet for the manufacturer’s instructions.
-Do not weld/cut near materials that will emit toxic fumes when heated. Vapors
from cleaners, sprays and degreasers can be highly toxic when heated.
UV and IR Arc Rays
The plasma cutting arc produces ultraviolet (UV) and infrared (IR)
rays that can cause injury to your eyes and skin. Do not look at the
plasma cutting arc without proper eye protection.
- Always use safety glasses, a shield or a helmet that meets ANSI Z49.1
standards for plasma cutting.
- Cover all bare skin areas exposed to the arc with protective clothing and shoes.
Flame-retardant cloth or leather shirts, coats, pants or coveralls are available for
protection.
-Use screens or other barriers to protect other people from the arc rays emitted
from your plasma cutting arc.
-Warn people in your cutting area when you are going to strike an arc so they
can protect themselves.
Fire Hazards
Do not cut on containers or pipes that contain or have had flammable,
gaseous or liquid combustibles in them. Plasma cutting creates
sparks and heat that can ignite flammable and explosive materials.
