• 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.
• 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).
Caution! The machine may still be live when the power cord is disconnected.
• After turning off the unit and disconnecting the voltage cable, check the voltage on the input
capacitor and make sure that the voltage value is zero, otherwise do not touch the unit components.
4.6. Gases and fumes
Caution! Gas can be hazardous to health or lead to death!
• Always keep a distance from the gas outlet.
• When welding, pay attention to the exchange of air, avoid inhaling the vapors.
• Remove chemical substances (greases, solvents) from the surface of the workpieces as they burn
under high temperature, giving off poisonous fumes.
• Welding galvanized parts is allowed only with efficient extraction with filtration and a supply of
clean air. Zinc vapors are very toxic, and the symptom of poisoning is the so-called zinc fever.
