WELDING FUMES AND GASES
Fumes, gas and dust produced during welding are hazardous to health. It is mandatory to ensure adequate ventilation and/
or extraction to keep fumes and gas away from the work area. Using an air fed welding helmet is recommended in case of
insufficient ventilation in the workplace.
Check that the air supply is effective by referring to the recommended safety regulations.
Precautions must be taken when welding in small areas, and the operator will need supervision from a safe distance. Welding certain pieces of metal
containing lead, cadmium, zinc, mercury or beryllium can be extremely toxic. The user will also need to degrease the workpiece before welding.
Gas cylinders must be stored in an open or ventilated area. They must be stored vertically and held by a support or trolley to limit the risk of fall.
Do not weld in areas where grease or paint are stored.
FIRE AND EXPLOSION RISKS
Protect the entire welding area. Flammable materials must be moved to a minimum safe distance of 11 meters.
A fire extinguisher must be readily available near the welding operations.
Be careful of weld spatter and sparks, even through cracks. If not careful then this could potentially lead to a fire or an explosion.
Keep people, flammable materials/objects and containers that are under pressure at a safe distance.
Welding in closed containers or pipes should be avoided and , if they are opened, they must be emptied of any flammable or explosive material (oil,
fuel, gas ...).
Grinding operations should not be carried out close to the power supply or any flammable materials.
ELECTRICAL SAFETY
The electrical mains used must have an earth terminal. An electric shock could cause serious injuries or potentially even deadly
accidents.
Never make contact with live parts inside or outside the current source (cables, electrodes, arms, guns...) as they are connected to the welding circuit.
Before opening the device, it is imperative to disconnect it from the mains and wait 2 minutes, so that all the capacitors are discharged.
Damaged cables and torches must be changed by a qualified and skilled professional. Make sure that the cable cross section is adequate with the
usage (extensions and welding cables). Always wear dry clothes which are in good condition in order to be isolated from the welding circuit. Wear
insulating shoes, regardless of the workplace/environment in which you work in.
Warning! Very hot surface. Risk of burns.
• The parts and pieces that have just been heated are hot and may cause burns when manipulated.
• Do not touch any hot parts with your hands.
• Wait for the parts and pieces to cool down before handling them.
• In case of burn, rinse thoroughly with water and consult a doctor as soon as possible.
EMC MATERIAL CLASSIFICATION
This Class A machine is not intended to be used on a residential site where the electric current is supplied by the domestic
low-voltage power grid. There may be issues in ensuring electromagnetic compatibility on these sort of sites, due to conducted
interferences as well as radiation.
This equipment does not comply with IEC 61000-3-12 and is intended to be connected to private low-voltage systems interfacing
with the public power grid only at the medium- or high-voltage level. If connected to a public low-voltage power grid, the
installer or user of the machine has to ensure, by checking with the network operator, that the device can be connected.
ELECTROMAGNETIC INTERFERENCES
The electric current flowing through any conductor causes electrical and magnetic fields (EMF). The welding current generates an
EMF around the welding circuit and the welding equipment.
The EMF electromagnetic fields can interfere with certain medical implants, such as pacemakers. Protective measures must be taken for people having
medical implants. For example, by restricting access to passers-by or conducting an individual risk evaluation for the welders.
All welders should take the following precautions in order to minimise exposure to the electromagnetic fields (EMF) generated by the welding circuit:
• position the welding cables together – if possible, attach them;
• keep your head and upper body as far as possible from the welding circuit;
• never wrap the cables around your body;
• never position your body between the welding cables. Hold both welding cables on the same side of your body;
• connect the earth clamp as close as possible to the welding area;
• do not work too close to, do not lean and do not sit on the welding machine
• do not weld when transporting the welding machine or its wire feeder.
