Electric Safety - GYS EXPERT 130 Manual De Instrucciones

Translation of the original instructions
The fumes, gases and dust produced during welding are hazardous. It is mandatory to ensure adequate
ventilation and/or extraction to keep fumes and gases away from the work area. An air fed helmet
is recommended in cases of insufficient air supply in the workplace. Check that the air intake is in
compliance with safety standards.
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 welding 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.
Welding 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.
This equipment complies with the IEC 61000-3-12 standard. This equipment complies with the IEC 61000-3-11 standard.
ELECTROMAGNETIC INTERFERENCES
The electric currents flowing through a conductor cause electrical and magnetic fields (EMF). The
welding 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 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 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;
