FIRE AND EXPLOSION HAZARDS
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. It can be the source of fire or explosion.
Keep people, flammable materials/objects and containers 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 CYLINDERS
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 welding machine 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 cylinder valve, it is necessary to remove the tip of the valve and make sure that the gas meets your welding requirements.

ELECTRICAL SAFETY

The electrical mains used must have an earth terminal. Use the recommended fuse size.
An electrical shock can directly or indirectly cause serious and potentially deadly accidents.
Do not touch any live part of the machine (inside or outside) when it is plugged in (torches, clamps, 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 and authorised person.
Make sure that the cable cross section (extension lead and welding cables) is in accordance with the application.
Always wear dry clothes which are in good condition in order to be isolated from the welding circuit. Wear insulating shoes, regardless of the
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 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 it is connected to a public low-voltage power grid, the
installer or user of the machine has to ensure, by checking with the operator of the distribution network, that the device can
be connected.

ELECTROMAGNETIC EMISSIONS

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. Protection 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 chest 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 sit on and do not lean on the welding machine
• do not weld when you're carrying the welding machine or its wire feeder.
