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.

8. Replacing the drive roller groove

CAUTION! All maintenance, replacement of parts, repairs or adjustments should be carried out with the power supply disconnected from the device.

If you need to change the wire diameter, also replace the drive roller or adjust the position of the drive roller.

Be aware of the different types of rolls depending on the welding wire used:

Rollers with a "V" groove.

Rollers with a "U" groove.

Rollers with a knurled groove.

The most popular are rollers with a V-shaped groove. Such rollers are designed for the most popular welding wires. In the case of aluminum wires, rollers with a U-shaped groove are used. This is due to the fact that the aluminum wire is more prone to crushing, so that the wire does not deform, it is necessary to use an appropriate roller. A separate narrow group of feeder rollers are knurled rollers for cored wire (FCAW).

9. Replacing the welding wire

CAUTION! All maintenance, replacement of parts, repairs or adjustments should be carried out with the power supply disconnected from the device.

1. Open the spool housing by pressing the opening buttons and install the spool so that it rotates counterclockwise.
2. Secure the spool with the spool lock.
3. Unfasten the end of the wire from the spool and hold it in your hand at all times to prevent the spool from unwinding.
4. Straighten the end of the wire for about 20cm and cut off the bent part.
5. Open the pressure adjustment lever that opens the feeding mechanism.
6. Guide the wire through the rear wire guide to the welding gun wire guide.
7. Close the feeding mechanism and secure it with the pressure adjustment lever. Make sure that the wire runs in the groove of the drive roll.
8. Adjust the pressure of the lever, but do not exceed half of the scale. Too much pressure can damage the wire. On the other hand, if the pressure is too weak, the wire will slide in the feed mechanism and the wire will not move smoothly.
9. Make sure that the contact tip suitable for the installed welding wire is inserted into the welding gun. If necessary, replace the contact tip.
10. Press the trigger of the welding gun and wait for the wire to come out.

CAUTION! Getting the wire out of the burner requires applying power to the unit. Do not touch any earthed objects with the torch; otherwise, an electric arc may form.

1. Close the spool housing cover.

CAUTION! When inserting the wire into the gun, do not point the gun at yourself or at other people. Do not place your hand, e.g., in front of the tip, as the cut end of the wire is very sharp. Also, keep your fingers away from the feed roller, as this may cause your fingers to be pinched between the rollers.
