User manual
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 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.
GAS CYLINERS
Gas leaking from the cylinders can lead to suffocation if present in high concentration around the work area (ventilation required).
Transport must be done safely: 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 two uses. Beware of temperature variations and sun exposure.
The cylinder must not be in contact with a flame, electric arc, torch, earth clamp or all other sources of heat.
Always keep gas cylinders away from electrical circuits, and therefore never weld a cylinder under pressure.
Be careful when opening the valve on the gas bottle, it is necessary to remove the tip of the valve and to ensure that the gas meets your welding
requirements.
ELECTRICAL SAFETY
The electrical mains used must have an earth terminal. Use the recommended fuse size.
An electric shock could cause serious injuries or potentially even deadly accidents.
Do not touch any live part of the machine (inside or outside) when it is plugged in (Torches, earth cable, cables, electrodes) because 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.
Do not touch the torch or electrode holder and the earth clamp at the same time.
Damaged cables and torches must be changed by a qualified technician. 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.
EMC 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 potential difficulties in ensuring electromagnetic compatibility at these sites, due to conducted
interferences as well as radiation.
This equipment complies with the IEC 61000-3-11 standard.
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 supply only at the medium- or high-voltage level. On a public low-voltage power grid, it is the responsibility of
the installer or user of the device to ensure, by checking with the operator of the distribution network, which 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 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 your torso and head as far as possible from the welding circuit
• never wrap the cables around the body.
• do not position the body between the welding cables. Hold both welding cables on the same side of the body;
