and Precautions

Diagram and safety explanation 

Cutting sparks can cause explosion or fire. 

Keep flammable materials away from cutting. Do not cut 

near flammable materials. 

Cutting sparks can cause fires. Have a fire extinguisher 

nearby, and have a watchperson ready to use it. 

Do not cut on drums or any closed container. 

The plasma arc can cause injury and burns. 

Turn off power before disassembling torch. 

Do not grip material near cutting path. 

Wear complete body protection.

Electric shock from torch or wiring can kill. 

Wear dry insulating gloves. Do not wear wet or damaged 

gloves. 

Protect yourself from electric shock by insulating yourself 

from work and ground. 

Disconnect input plug or power before working on machine. 

Breathing cutting fumes can be hazardous to your health. 

Keep your head out of fumes.

Use forced ventilation or local exhaust to remove fumes

Use ventilating fan to remove fumes. 

Arc rays can burn eyes and injure skin. 

Wear hat and safety glasses. 

Use ear protection and button 

shirt collar. Use welding helmet 

with correct shade of filter. 

Wear complete body protection. 

Become trained and read the 

instructions before working on the 

machine or cutting.

Do not remove or paint over (cover) the label. 

Some safety precautions BOC 

recommends are as follows:

• Repair or replace defective cables immediately.

• Never watch the plasma arc except through  

lenses of the correct shade.

• In confined spaces, adequate ventilation  

and constant observation are essential.

• Leads and cables should be kept clear  

of passageways.

• Keep fire extinguishing equipment at a handy location  

in the workshop.

• Keep primary terminals and live parts effectively covered.

• Never strike an electrode on any gas cylinder.

• Never use oxygen for venting containers.
