SAFETY WARNINGS

ELECTRIC SHOCK

1. Do not touch live electrical parts.

2. Never use electrode holders or cables which are damaged.

3. Keep the working environment, equipment, cables and clothing free from

grease, oil, moisture and dirt.

4. Ensure the welding machine has been correctly earthed.

5. The operator must be insulated from the floor and work bench using a dry

insulation mat.

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

7. Keep welding cables away from power cables.

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

9. Remove the plug from the mains socket when not in use.

10. Ensure the earth connector is secured to bare metal adjacent to the weld,

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

maintained.

FUMES & GASES

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

Inhalation of these fumes is hazardous to health.

2. Keep your face away from the weld to avoid breathing the fumes.

3. If welding in confined spaces ensure adequate ventilation and use a fume

extractor.

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

FIRE OR EXPLOSION

1. Welding can cause fire and explosions. Precautions should be taken to

prevent these hazards.

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

OPERATE THIS PRODUCT AND KEEP THESE INSTRUCTIONS IN A SAFE PLACE.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Servi[email protected]

2. Before starting work ensure the area is clear of flammable materials and

move any combustible materials to a safe distance, especially substances

likely to generate a dangerous vapours.

3. The welding arc can cause serious burns. Avoid contact with skin.

4. Sparks and molten metal may be ejected during welding. Take

precautions to prevent fire.

5. Sparks and molten metal can pass through gaps. Be aware that fire can

start out of sight.

6. Do not weld to pressurised containers. or containers containing flammable

vapours e.g. fuel tanks.

7. Always have appropriate fire fighting equipment to hand suitable for use in

electrical environments.

8. Avoid carrying any fuels with you e.g. cigarette lighters or matches.

PERSONAL PROTECTION

1. The body should be protected by suitable clothing.

2. The use of neck protection may be necessary against reflected radiation.

3. Arc machines generate a magnetic field which is detrimental to

pacemakers. Consult your doctor before going near active welding

equipment/operations.

4. The UV and IR radiation generated by welding is highly damaging to the

eyes, causing burns. This can also affect the skin.

5. Always use suitable welding shields equipped with appropriate filters.

6. Where there are pedestrians and traffic ensure a protective screen is used

to avoid accidental arc glare.

7. Do not weld in the vicinity of children or animals and ensure no one is

looking before striking an arc.

8. Wear hearing protection if required.

9. Allow the weld to cool. Hot metal should never be handled without gloves.

10. Take care when adjusting or maintaining the electrode/holder, that it has

had time to cool sufficiently and the welder is disconnected from the mains

supply.

11. First aid facilities and a qualified first aid person should be available unless

medical facilities are close by, for immediate treatment of flash burns of

the eyes and skin burns.

12. Flammable hair sprays/gels should not be used by persons welding.

4. Avoid wearing oily or greasy clothing.

5. Wear protective head and shoulder coverings if welding overhead.

6. Wear a helmet with safety goggles or glasses with side shields underneath,

appropriate filter lenses or plates (protected by clear glass). This is a MUST

for welding (and chipping) to protect the eyes from radiant energy and

spatter. Replace cover glass when broken, pitted, or spattered.

NOTE: All protective wear inc. masks & head shields MUST comply with

Personal Protective Equipment Directive 89/686/EEC.

ADDITIONAL SAFETY PRECAUTIONS FOR WELDING

1. Always ensure that there is ample free air circulating around the outer

casing of the machine, and that the louvres are unobstructed.

2. Always inspect the cable before use to ensure it is in good condition.

3. Always remove all flammable materials from the welding area.

4. Always keep a fire extinguisher handy;-Dry Powder, CO2or BCF, NOT Water.

5. Never remove the cover panels unless the machine is disconnected from

the power supply, and never use the machine with the panels removed.

6. Never attempt any electrical or mechanical repair unless you are a

qualified technician. If you have a problem with the machine contact your

local CLARKE dealer.

7. Never use or store in a wet/damp environment.

8. Never continue to weld, if, at any time, you feel even the smallest electric

shock. Stop welding IMMEDIATELY and DO NOT attempt to use the
