Operating manual
RISK OF FIRE AND EXPLOSION
Fully protect the welding area; flammable materials must be at least 11 metres away.
Fire-fighting equipment must be available in the vicinity of welding operations.
Beware of hot material or sparks, as even through cracks they can be a source of fire or explosion.
Keep people, flammable objects and pressurised containers at a safe distance.
Do not weld in closed containers or tubes, and if they are open, empty them of all flammable or explosive materials (oil, fuel, gas residues, etc.).
Do not grind in the direction of the welding current source or flammable materials.
GAS CYLINDERS
The gas coming out of the cylinders can be a source of suffocation if concentrated in the welding area (ventilate well).
Cylinders must be transported in complete safety, with the cylinders closed and the welding current source switched off. They
must be stored vertically and held by a support to limit the risk of falling.
Close the cylinder between uses. Beware of temperature variations and exposure to sunlight.
The cylinder must not come into contact with a flame, electric arc, torch, earth clamp or any other source of heat or incandescence.
Keep away from electrical and welding circuits and never weld a cylinder under pressure.
When opening the cylinder valve, keep the head away from the fittings and ensure that the gas used is suitable for the welding process.
ELECTRICAL SAFETY
The electrical network used must be earthed. Use the fuse size recommended on the rating plate.
An electric shock can be a source of serious direct or indirect accident, or even death.
Never touch live parts inside or outside the live current source (torches, clamps, cables, electrodes) as these are connected to the welding circuit.
Before opening the welding current source, disconnect it from the mains and wait 2 minutes. so that all the capacitors are discharged.
Do not touch the torch or electrode holder and the earth clamp at the same time.
If the cables or torches are damaged, they should be replaced by qualified and authorised personnel. Size the cable cross-section to suit the
application. Always use dry clothing in good condition to insulate yourself from the welding circuit. Wear insulating footwear in all working environments.
CEM CLASSIFICATION OF EQUIPMENT
This Class A equipment is not intended for use in a residential site where the electrical current is supplied by the public low-
voltage supply network. There may be potential difficulties in ensuring electromagnetic compatibility in such sites, due to
conducted, as well as radiated, radio frequency interference.
Provided that the impedance of the public low voltage supply network at the point of common coupling is less than Zmax = 0.450
Ohms, this equipment complies with IEC 61000-3-11 and may be connected to the public low voltage supply networks. It is the
responsibility of the installer or user of the equipment to ensure, by consulting the distribution network operator if necessary,
that the network impedance complies with the impedance restrictions.
This equipment complies with IEC 61000-3-12.
ELECTRO-MAGNETICS
Electric current passing through any conductor produces localised electric and magnetic fields (EMF). Welding current produces an
electromagnetic field around the welding circuit and welding equipment.
Electromagnetic EMF fields can interfere with certain medical implants, such as pacemakers. Protective measures must be taken for people with
medical implants. For example, access restrictions for bystanders or an individual risk assessment for welders.
All welders should use the following procedures to minimise exposure to electromagnetic fields from the welding circuit:
•position the welding cables together - secure them with a clamp, if possible;
•position themselves (torso and head) as far away from the welding circuit as possible;
•never wrap the welding cables around the body;
•do not position the body between the welding cables. Hold both welding cables on the same side of the body;
•connect the return cable to the workpiece as close as possible to the area to be welded;
•do not work next to the welding power source, do not sit on it or lean against it;
•do not weld when transporting the welding power source or the wire feeder.
Pacemaker wearers should consult a physician before using this equipment.
Exposure to electromagnetic fields during welding may have other health effects that are not yet known.
