4.1. General

• Take care of your own safety and the safety of bystanders by carefully reading and following the instructions in the unit manual.
• Only qualified personnel should be allowed to start up, use, service and repair the unit.
• Do not misuse the unit.

4.2. Guidelines for securing fire hazardous work

Preparing the building and rooms for fire hazardous works consists in:

• cleaning the rooms or places where the work will be carried out of any flammable materials and contamination;
• moving all flammable and non-flammable objects in flammable packaging away to a safe distance;
• securing materials that cannot be removed, e.g. welding spatter, by covering them with e.g. sheet metal, gypsum boards, etc;
• checking whether materials or objects susceptible to ignition in adjacent rooms do not require local protection;
• sealing with non-combustible materials all installation and ventilation openings, etc., in the vicinity of the work site;
• protecting electrical and gas cables with flammable insulation against welding splashes or mechanical damage, if they are located within the risk range of fire hazardous work;
• make sure that painting or other work with flammable substances is not being carried out at the location where the work is to be done.

Sparks may cause fires

Welding sparks can cause fires, explosions and burns to unprotected skin. Wear welding gloves and protective clothing when welding. Remove or secure all flammable materials and substances from the work area. Do not weld closed containers or tanks that have contained flammable liquids. Such containers or tanks should be flushed before welding to remove flammable liquids. Do not weld near flammable gases, vapors or liquids. Fire fighting equipment (fire blankets and powder or snow extinguishers) should be located near the work area in a visible and easily accessible location.

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 12m 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.

• 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, avoiding gas inhalation.
- 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.
