B - GENERAL SAFETY INSTRUCTIONS
ELECTRICAL SAFETY
Connection to the mains
Before you connect your machine, please make sure that:
—The meter, the overintensity protection system and the electrical installation are compatible with its
maximum power rating and its supply voltage.
—It can be connected, in a single-phase or three-phase with earth system, to a socket compatible with the
plug on its power cord (mobile equipment).
—If the cable is connected to a fixed point, the earth connection, if there is one, may never be cut off by the
system offering protection from electric shocks.
—The switch, if there is one, is set to OFF.
Workstation
Arc welding and cutting requires strict compliance with safety requirements in respect of electrical currents (Order
of 14 December 1988).
Servicing
Before any internal checking or repairs, make sure that the machine has been disconnected from the electrical
installation by locking it out:
—Accidental connection of the cable of a fixed installation has been made impossible
—Cutting off by means of a fixed connection device relates to all poles (phase and neutral. It must be in the
OFF position, with no possibility of being put into service by mistake
Some machines have an HV/HF arc ignition circuit (indicated by a plate). Never work inside such a box.
Any work on electrical installations must be carried out by persons qualified for that purpose (Decree 88-1056 of 14
November 1988, Section VI, Art 46).
Maintenance
From time to time, check that the machinery and its electrical accessories - connectors, flexible cables and
extension cords - are correctly insulated and connected.
Work for maintaining and repairing insulating enclosures and ducts may not be carried out in a haphazard manner
(Section VI, Art. 47 Decree 88-1056 of 14 November 1988).
—All repairs are to be carried out by specialists, or better yet, defective accessories should be replaced.
—Regularly check that the electrical connections are tight, with no heating.
Any fans placed in a circuit in which the air is laden with dust must be cleaned from time to time. That is because
the turbine may be fouled and become unbalanced, leading to increased noise and premature wear and tear of
bearings. Maintenance is required after no more than every six months, depending on the type of dust treated.
The fan is an essential element of your extraction system.
Incorrect operating or inadequate maintenance could make the operating position less safe. That is why the fan
must be maintained in perfect condition.
Your installation has been selected for a specific application. The turbine is characterised by a duty point based on
extraction speed (speed of air in the piping) and head loss.
In accordance with the regulations of CARSAT and INRS, the installation must be inspected from time to time to
make sure that it continues to comply with its reference values.

PERSONAL PROTECTION
Risks of external injury relating to welding operations
Whole body
—The operator must be clothed and protected to suit the requirements of the job.
—Make sure that no part of the bodies of operators and helpers can come in contact with metal pieces or
parts that are live or are liable to become live accidentally.
—Do not wind electricity cables around the body.
—Keep safety guards and panels in place.
—The operator must always wear personal insulating protection (Order of 14 December 1988, Section III).
—The protection must be kept dry to prevent electric shocks if it is wet, or ignition in the presence of oil.
Personal protective equipment worn by operators and their helpers - gloves, aprons, safety shoes - offer the added
benefit of protecting them from burns due to hot parts, splatter and slag.
Also make sure the PPE is in good condition and replace it before it ceases to offer protection.
Face and eyes
It is indispensable to protect the following:
—Eyes, from arc injury (dazzling due to visible light from the arc, and infrared and ultraviolet radiation).
—Hair, face and eyes from welding splatter and projection of slag during weld cooling
The welding mask, when used under or without a helmet, must always be equipped with a protective filter, the
shade of which depends on the intensity of the welding arc current (Standards NF S77-104 A 88-221 A88-222).
The coloured filter may be protected from impacts and splatter by a transparent glass located on the front of the
mask.
If the filter is replaced, use another one with the same part number (shade number).
Persons in the vicinity of the operator, especially any helpers, must be protected by means of suitable screens,
anti-UV goggles or, if needed, masks with suitable protective filters (EN 139).

8695 8421/A
-4 CHD
Specific case of chlorine solvents in welding: (used for cleaning or degreasing).
—The fumes from these solvents can be changed into toxic gases when subjected to arc radiation, including
from a distance.
—Such solvents may therefore not be used in locations where electric arcs occur, if the solvents are not in a
sealed enclosure.
Work in confined spaces
Examples:
—Mine roads
—Piping and pipelines
—Ship docks, pits, manholes, cellars
—Tanks
—Ballast tanks
—Silos
—Reactors
Special precautions must be taken before undertaking welding operations in such enclosures, where suffocating
and poisoning and fire and explosion risks are very great.
A work permit procedure setting out all the safety measures must systematically be set up.
Make sure that ventilation is appropriate, paying special attention to:
—under-oxygenation
—over-oxygenation
—excess fuel gas

8695 8421/A
CHD -5
FILTRATION OF FUMES AND DUST
Important
Note that CHD high-vacuum units may be used in combination with a self-cleaning cyclone filter of the 2 or 4 CD
type.
Mechanical or electrostatic filtration systems are effective for the filtration of solid but not gaseous particles (exterior
discharge).
If recycling is effective (not recommended), make sure the workplace where the machine or machines are placed is
properly ventilated, so as to not reach the OELV (occupational exposure limit values) of gaseous pollutants relating
to the specific pollution generated by the method (welding, cutting).
Field of use
Filtration of solid particles and dry dust, non-flammable gas, with no risk of explosion.
—Zinc, paper, flour, plant leaves, graphite, aluminium and other such dust is to be excluded, because
electrostatic discharge or welding splatter would present a risk for those using the filter.
—The air flow through the filter medium must not be at a temperature above 80 °C.
—This machine is not designed for extracting chemicals.
—The choice of machine is made to suit the pollutants to treat. Extraction at source of the pollutant is only
effective if the machine is operating at its nominal power (air flow at the nozzle).
Take particular care to:
—Not obstruct the air outlet of the machine.
—Not introduce external elements into the filter (paper, cloths, cigarette butts etc.)
—Replace the filter medium with new original LINCOLN ELECTRIC medium, which alone can guarantee the
filtration characteristics.
—Replace the hoses if they are pierced.
—Regularly clean the metal pre-filter on those machines that have one

VARIABLE DRIVE CONFIGURATION
1- Operating principle :
The variable drive is used for one of its most basic functions, namely overspeed operating.
Thanks to the types of fan curve used, we can make a fan operate at a speed from 70 to 87 Hz.
With conventional starting up, it would not be possible to operate it above 50 Hz (electrical system frequency).
Thus, we can operate at overspeed while keeping the system vacuum constant.
