GENERAL SAFETY INSTRUCTIONS

ELECTRIC SHOCK

• Always remove the plug from the socket and wait 5 minutes to allow the 

capacitors to discharge before carrying out servicing or maintenance.

• Do not touch live electrical parts.

• Never use electrode holders or cables which are damaged.

• Keep the working environment, equipment, cables and clothing free from 

grease, oil, moisture and dirt.

• Ensure the welding machine has been correctly earthed.

• The operator must be insulated from the floor and work bench, using a dry 

insulation mat.

• Always ensure a second person is present in case of accident.

• Never change electrodes with bare hands or damp gloves.

• Keep welding cables away from power cables.

• Regularly inspect the condition of the cables for signs of damage.

• Remove the plug from the mains socket when not in use, do not leave the 

machine unattended.

• Ensure the earth clamp is secured to bare metal adjacent to the weld seam, 

and when not in use, is insulated for safety. - Keep all equipment well 
maintained.

• The operator shall prevent gas cylinders in the vicinity of the workpiece from 

becoming part of the welding circuit.

FUMES & GASES

• The welding process generates hazardous fumes as a by-product. Inhalation 

of these fumes is hazardous to health.

• Keep your head away from the weld to avoid breathing the fumes.

• If welding in confined spaces, ensure adequate ventilation and use a fume 

extractor.

• By-products of welding can react to create a toxic/explosive environment.

WARNING: WHEN USING ELECTRICAL TOOLS, BASIC SAFETY 
PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF 
FIRE, ELECTRIC SHOCK AND PERSONAL INJURY. 

WARNING: READ ALL THESE INSTRUCTIONS BEFORE ATTEMPTING TO
