Electric Safety - GYS PLASMA CUTTER 25 K Manual Del Usuario

MADE IN FRANCE
Care must be taken when welding in small areas, and the operator will need supervision from a safe distance. Welding certain pieces of metal
containing lead, cadmium, zinc, mercury or beryllium can be extremely toxic. The user will also need to degrease the workpiece before welding.
Gas cylinders must be stored in an open or ventilated area. The cylinders must be in a vertical position secured to a support or trolley.
Do not weld in areas where grease or paint are stored.
FIRE AND EXPLOSION RISKS
Protect the entire cutting area. Compressed gas containers and other inflammable material must be moved to a minimum safe
distance of 11 meters.
A fire extinguisher must be readily available.
Be careful of spatter and sparks, even through cracks. It can be the source of a fire or an explosion.
Keep people, flammable objects and containers under pressure at a safe distance.
Cutting of sealed containers or closed pipes should not be undertaken, and if opened, the operator must remove any inflammable or explosive
materials (oil, petrol, gas...).
Grinding operations should not be directed towards the device itself, the power supply or any flammable materials.

ELECTRIC SAFETY

The machine must be connected to an earthed electrical supply. Use the recommended fuse size.
An electrical discharge can directly or indirectly cause serious or 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 earth clamp at the same time.
Damaged cables and torches must be changed by a qualified and skilled 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 difficulties in ensuring electromagnetic compatibility on these
sites, because of the interferences, as well as radio frequencies.
PLASMA CUTTER 35 KF and 31 FV : This equipment complies with the IEC 61000-3-12 standard.
PLASMA CUTTER 25 K : 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 currents flowing through a conductor cause electrical and magnetic fields (EMF). The cutting current generates an
EMF field around the welding circuit and the welding equipment.
The EMF fields may disrupt some medical implants, such as pacemakers. Protection measures should be taken for people wearing medical implants.
For example, access restrictions for passers-by or an individual risk evaluation for the welders.
All operators should take the following precautions in order to minimise exposure to the electromagnetic fields (EMF) generated by the cutting 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 area being welded;
• do not work too close to, do not lean and do not sit on the welding machine.
People wearing pacemakers are advised to consult their doctor before using this device.
Exposure to electromagnetic fields while welding may have other health effects which are not yet known.
