Cylinders can explode
Use only approved gas cylinders and a properly functioning regulator. Cylinders should be transported,
stored and positioned upright. Protect cylinders from heat, tipping and mechanical damage. Keep all
parts of gas installation in good condition: cylinder, hose, fittings, regulator.
Welded materials can cause burns
Never touch welded parts with unprotected body parts. Always wear welding gloves and pliers when
touching or moving welded material.
4.3. Preparation of the workplace for welding
Caution! Welding can cause a fire or explosion.
• Observe the health and safety regulations for welding work and equip the workplace with an
appropriate fire extinguisher
• Welding in places where flammable materials can ignite is forbidden.
• Welding in an atmosphere containing an explosive mixture of flammable gases, vapors, mists or
dusts with air is forbidden.
• Remove all flammable materials within a radius of 12 m from the welding site and, if this is
impossible, cover the flammable materials with a non-flammable cover.
• Take precautionary measures against sparks and glowing metal particles.
• Note that sparks or hot metal splinters can penetrate through slots or openings in protective caps,
covers or screens.
• Do not weld tanks or barrels that contain or have contained flammable substances. Do not weld in
their vicinity either.
• Do not weld pressurized tanks, pressure lines or pressure tanks.
• Always provide sufficient ventilation.
• Make sure you are in a stable position before starting to weld.
4.4. Personal protective equipment
Caution! Arc radiation can damage the eyes or skin of the body.
• When welding, wear clean, oil-free protective clothing made of non-flammable and non-conductive
material (leather, thick cotton), leather gloves, high boots and a protective hood.
• Before welding, get rid of any flammable or explosive items such as propane-butane lighters and
matches.
• Use face protection (helmet or shield) and cover the eyes with a shade matching the welder's
eyesight and welding current. The safety standards suggest a No. 9 (minimum No. 8) tint for any
amperage below 300 A. Lower shield tints may be used if the arc is covered by the workpiece.
• Always use approved safety glasses with a side shield under the helmet or other shield.
• Use workplace shields to protect others from glare or spatter.
• Always wear earplugs or other hearing protection against excessive noise and to prevent spatter
from entering your ears.
• Warn bystanders against looking at the electric arc.
4.5. Protection against shock
Caution! Electric shock can be fatal.
• Plug the power cord into the nearest outlet and route it in a practical and safe way. Avoid
spreading the cable carelessly around the room on an unstudied surface, which may result in electric
shock or fire.
• Contact with electrically charged parts can cause an electric shock or severe burns.
• The electric arc and the working area are electrically charged when the current flows.
• The input circuit and the internal circuitry of the unit are also live when the power is on.
