User manual
Welding should not be carried out near grease or paint.
RISK OF FIRES AND EXPLOSIONS
Fully shield the welding area, flammable materials should be kept at least 11 metres away.
Fire fighting equipment should be kept close to wherever the welding activities are being undertaken.
Beware the expulsion of hot spatter or sparks, even through cracks, which can cause fires or explosions.
Keep people, flammable objects and pressurised containers at a safe distance.
Welding in closed containers or tubes is to be avoided. If the containers or tubes are open, they must be emptied of all flammable or explosive
materials (oil, fuel, gas residues, etc.).
Grinding work must not be directed towards the source of the welding current or towards any flammable materials.
GAS CYLINDERS
Gas escaping from cylinders can cause suffocation if there is too high a concentration of it in the welding area (ensure good
ventilation).
The machine must be transported in complete safety: gas cylinders must be closed and the welding power source turned off. They
should be stored upright and supported to limit the risk of falling.
Close the cylinder between uses. Beware of temperature variations and exposure to the sun.
The cylinder must not come into contact with flames, arcs, torches, earth clamps or any other sources of heat or ignition.
Be sure to keep it away from electrical and welding circuits. Never weld a pressurised cylinder.
When opening the cylinder valve, keep your head away from the valve and ensure that the gas being used is suitable for the welding process.
ELECTRICAL SAFETY
The electrical network used must be earthed. Use the recommended fuse size from the rating plate.
An electric shock can be the source of a serious accident, whether directly or indirectly, or even death.
Never touch live parts connected to the live current, either inside or outside the power source casing unit (torches, clamps, cables, electrodes), as
these items are connected to the welding circuit.
Before opening the welding machine's power source, disconnect it from the mains and wait two minutes to ensure that all the capacitors have fully
discharged.
Do not touch the torch or the electrode holder and the earth clamp at the same time.
If the cables or torches become damaged, they must be replaced by a qualified and authorised person. Measure the cable cross-section according to
the intended application. Always use dry and in-fact clothing to insulate yourself from the welding circuit. Alongside this, wear well-insulated footwear
in all working environments.
EMC CLASSIFICATION
This Class A device is not intended for use in a residential environment where power is provided by the public low-voltage local
supply network. Ensuring electromagnetic compatibilty may be difficult at these sites due to conducted, as well as radiated,
radio frequency interference.
Provided that the impedance of the public low-voltage supply network is less than Zmax = 0.29 Ohms at the common coupling
point, this equipment complies with IEC 61000-3-11 and can be connected to public low-voltage electrical supply. It is the
responsibility of the fitter or operator of the equipment to ensure, by consulting the electricity distribution network provider if
necessary, that the network impedance complies with impedance restrictions.
This equipment complies with the IEC 61000-3-12 standard.
ELECTROMAGNETIC INTERFERENCES
An electric current passing through any conductor produces localised electric and magnetic fields (EMF). The welding current
produces an electromagnetic field around the welding circuit and the welding equipment.
Electromagnetic fields (EMFs) can interfere with some medical devices, for example pacemakers. Protective measures must be taken for people with
medical implants. For example, restricted access for onlookers or an individual risk assessment for welders.
All welders should use the following guidelines to minimise exposure to the welding circuit's electromagnetic fields:
• position the welding cables together - securing them with a clamp if possible;
• position yourself (head and body) as far away from the welding circuit as possible,
• never wrap the welding cables around your body,
