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.
CLASSIFICATION
This equipment is Class B.
This equipment complies with the IEC 61000-3-12 standard.
This equipment complies with the IEC 61000-3-11 standard.
RECOMMANDATIONS TO ASSES THE AREA AND WELDING INSTALLATION
Overview
The user is responsible for installing and using the arc welding equipment in accordance with the manufacturer's instructions. If electromagnetic
disturbances are detected, it is the responsibility of the user of the arc welding equipment to resolve the situation with the manufacturer's technical
assistance. In some cases, this remedial action may be as simple as earthing the welding circuit. In other cases, it may be necessary to construct an
electromagnetic shield around the welding power source and around the entire piece by fitting input filters. In all cases, electromagnetic interferences
must be reduced until they are no longer bothersome.
Welding area assessment
Avant d'installer un matériel de soudage à l'arc, l'utilisateur doit évaluer les problèmes électromagnétiques potentiels dans la zone environnante.
Ce Before installing the machine, the user must evaluate the possible electromagnetic problems that may arise in the area where the installation is
planned.
. In particular, it should consider the following:
a) the presence of other power cables (power supply cables, telephone cables, command cable, etc...)above, below and on the sides of the arc
welding machine.
b) television transmitters and receivers ;
c) computers and other hardware;
d) critical safety equipment such as industrial machine protections;
e) the health and safety of the people in the area such as people with pacemakers or hearing aids;
f) calibration and measuring equipment
g)The isolation of the equipment from other machinery.
The user will have to make sure that the devices and equipments that are in the same room are compatible with each other. This may require extra
precautions;
h) make sure of the exact hour when the welding and/or other operations will take place.
The surface of the area to be considered around the device depends on the the building's structure and other activities that take place there. The area
taken in consideration can be larger than the limits determined by the companies.
Welding area assessment
Besides the welding area, the assessment of the arc welding systems intallation itself can be used to identify and resolve cases of disturbances. The
assessment of emissions must include in situ measurements as specified in Article 10 of CISPR 11: 2009. In situ measurements can also be used to
confirm the effectiveness of mitigation measures.
RECOMMENDATION ON METHODS OF ELECTROMAGNETIC EMISSIONS REDUCTION
a. National power grid: The arc welding machine must be connected to the national power grid in accordance with the manufacturer's
recommendation. If interferences occur, it may be necessary to take additional preventive measures such as the filtering of the power suplly network.
Consideration should be given to shielding the power supply cable in a metal conduit. It is necessary to ensure the shielding's electrical continuity
along the cable's entire length. The shielding should be connected to the welding current's source to ensure good electrical contact between the
conduct and the casing of the welding current source.
b. Maintenance of the arc welding equipment: The arc welding machine should be be submitted to a routine maintenance check according to
the manufacturer's recommendations. All accesses, service doors and covers should be closed and properly locked when the arc welding equipment
