Electric Safety - GYS PLASMA CUTTER 85A Manual Del Usuario

FIRE AND EXPLOSIONS RISKS
Protect the plasma cutting area completely, flammable materials must be kept at least 11 metres away.
Fire-fighting equipment must be present in the vicinity of plasma cutting operations.
Beware of hot material or sparks splashing even through cracks.
They can be the source of a fire or explosion.
Keep people, flammable objects and pressurized containers away from each other at a sufficient safety distance.
Plasma cutting in closed containers or tubes is to be avoided and if they are open, they must be emptied of any flammable or explosive material (oil,
fuel, gas residues, etc.).
Grinding operations must not be directed towards the device itself or 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 accidents, if not deadly.
Never touch live parts inside and outside of the device when it is powered on (Torches, clamps, cables, electrodes) as they are connected to the
welding circuit.
Before opening the device, it is imperative to disconnect it from the grid and wait 2 minutes. so that all the capacitors is discharged.
Do not touch the torch or electrode holder and earth clamp at the same time.
Be sure to change the cables and torches if they are damaged, to be performed by qualified and authorized personnel.
The dimensioning of these accessories should be sufficient.
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
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.
PLASMA CUTTER 85A / 125A :
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 produces localized electric and magnetic fields (EMF). The plasma cutting
current produces an electromagnetic field around the welding circuit and plasma cutting equipment.
- EMF electromagnetic fields can interfere with some medical implants, such as pacemakers. Protective measures must be taken for persons with
medical implants. For example, access restrictions for passers-by or an individual risk assessment for users.
All users should use the following procedures to minimize exposure to electromagnetic fields from the welding circuit:
- position the welding cables together - fix them with a clamp, if possible;
- position yourself (torso and head) as far away from the welding circuit as possible;
- never wrap the welding cables around the body;
- do not position the body between the welding cables. Hold both welding cables on the same side of the body;
- Connect the return cable to the processed part as close as possible to the area to be welded;
- do not work near, sit or lean against the plasma cutting current source;
- do not cut off when transporting the plasma cutting current source.
Carriers of pacemakers should consult a doctor before using this equipment.
Exposure to electromagnetic fields during plasma cutting may have other health effects that are not yet known.
RECOMMENDATIONS FOR EVALUATING THE PLASMA CUTTING AREA AND INSTALLATION
General information
The user is responsible for the installation and use of the plasma cutting equipment according to the manufacturer's instructions. If electromagnetic
disturbances are detected, it must be the responsibility of the user of the plasma cutting equipment to resolve the situation with the manufacturer's
technical assistance. In some cases, this corrective action may be as simple as grounding the welding circuit. In other cases, it may be necessary to
build an electromagnetic screen around the plasma cutting current source and the entire part with input filters mounted. In all cases, electromagnetic

interference must be reduced until it is no longer a nuisance.
