FIRE AND EXPLOSION HAZARDS
Protect the entire welding area. Compressed gas containers and other ammable materials must be moved to a minimum safe
distance of 11 meters.
A re extinguisher must be readily available near the welding operations.
Be careful of spatter and sparks, even through cracks. It can be the source of a re or an explosion.
People, ammable materials/objects and containers under pressure must be kept at a safe distance.
Welding of sealed containers or closed pipes should be avoided, and when opened, the operator must remove any inammable or explosive materials
(oil, petrol, gas...).
Grinding operations should not be directed towards the device itself, the power supply or any ammable materials.
GAS BOTTLE
Gas leaking from the bottles can lead to suffocation if present in high concentrations around the work area.
Transport must be done safely: bottles closed and welding machine switched off. Always keep cylinders in an upright position
securely fastened to a xed support to reduce the risk of falling.
Close the bottle between two operations. Be wary of temperature changes or exposure to sunlight.
The bottle must not be in contact with a ame, an electric arc, a torch, an earth clamp or all other sources of heat.
Always keep gas bottles at a safe distance from electrical circuits and thus never weld a pressurised bottle.
Be careful when opening the valve on the gas bottle, it is necessary to remove the tip of the valve and make sure the gas meets your welding
requirements.
ELECTRICAL SAFETY
The machine must be connected to an earthed electrical supply. Use the fuse size recommended on the signage table.
An electrical discharge can directly or indirectly cause serious and potentially deadly incidents.
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 earth clamp at the same time.
Damaged cables and torches must be changed by a qualied professional.
Make sure that the cable cross section is adequate with the usage (extensions and welding cables).
Always wear dry clothes in good condition, in order to be insulated from the electrical circuit. Wear insulating shoes, regardless of the environment
in which you work in.
EMC CLASSIFICATION
These Class A devices are not intended to be used on a residential site where the electric current is supplied by the public
network, with a low voltage power supply. There may be potential difculties in ensuring electromagnetic compatibility on these
sites, because of the interferences, as well as radio frequencies.
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 EMISSIONS
The electric current owing through any conductor causes electrical and magnetic elds (EMF). The welding current generates
an EMF around the welding circuit and the welding equipment.
The EMF may disrupt some medical implants, such as pacemakers. Protection measures must be taken for people using medical implants. For
example, by restricting access to poeple passing by or conducting an individual risk evaluation for the operators.
All welders should take the following precautions in order to minimise exposure to the electromagnetic elds (EMF) generated by the welding circuit::
• position the welding cables together – if possible, attach them;
• keep your head and torso as far as possible from the welding circuit;
• never enroll 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 on and do not sit on the welding machine
• do not weld when you’re carrying the welding machine or its wire feeder.
