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 carelessly unfolding
the cord on unchecked ground, which can lead to 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.
• Do not touch the live components.
• Wear dry, lint-free, insulated gloves and protective clothing.
• Use insulating mats or other insulating coatings on the floor that are large enough to prevent contact between the
body and the object or the floor.
• Do not touch the electric arc.
• Turn off the power supply before handling, cleaning or replacing the electrode.
• Make sure the grounding cable is properly connected and that the plug is properly inserted into the grounded
outlet. Improper grounding of the unit may result in a risk to life or health.
• Regularly check the power cables for damage or lack of insulation. A damaged cable should be replaced. Careless
repair of insulation may result in death or personal injury.
• Turn off the device when not in use.
• The cable must not be wrapped around the body.
• The workpiece must be properly grounded.
• Only accessories that are in good condition may be used.
• Damaged parts of the device must be repaired or replaced. Use safety belts when working at heights.
• All equipment and safety items should be stored in one place.
• Keep the tip of the handle away from the body when the trigger is activated.
• Attach the ground cable to the workpiece or as close to it as possible (e.g. to the workbench).
