2.a. Electric current flowing through any conductor causes
localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and
welding machines
2.b. EMF fields may interfere with some pacemakers, and
welders having a pacemaker should consult their physician
before welding.
2.c. Exposure to EMF fields in welding may have other health
effects which are now not known.
2.d. All welders should use the following procedures in order to
minimize exposure to EMF fields from the welding circuit:
2.d.1.
Route the electrode and work cables together - Secure
them with tape when possible.
2.d.2. Never coil the electrode lead around your body.
2.d.3. Do not place your body between the electrode and
work cables. If the electrode cable is on your right
side, the work cable should also be on your right side.
___________________________________________________
1.g. To prevent accidentally starting gasoline engines while
turning
the engine or welding generator during maintenance
work, disconnect the spark plug wires, distributor cap or
magneto wire as appropriate.
2.d.4. Connect the work cable to the workpiece as close as

3.a. The electrode and work (or ground) circuits
are electrically “hot” when the welder is on.
Do not touch these “hot” parts with your bare
gloves to insulate hands.
3.b. Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
In addition to the normal safety precautions, if welding
must be performed under electrically hazardous
conditions (in damp locations or while wearing wet
clothing; on metal structures such as floors, gratings or
scaffolds; when in cramped positions such as sitting,
kneeling or lying, if there is a high risk of unavoidable or
accidental contact with the workpiece or ground) use
the following equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c. In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic
welding gun are also electrically “hot”.
3.d. Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection
should be as close as possible to the area being welded.
3.e. Ground the work or metal to be welded to a good electrical
(earth) ground.
3.f.
Maintain the electrode holder, work clamp, welding cable and
welding machine in good, safe operating condition. Replace
damaged insulation.
3.g. Never dip the electrode in water for cooling.
3.h. Never simultaneously touch electrically “hot” parts of
electrode holders connected to two welders because voltage
between the two can be the total of the open circuit voltage
of both welders.

4.a. Use a shield with the proper filter and cover
plates to protect your eyes from sparks and
the rays of the arc when welding or observing
open arc welding. Headshield and filter lens
should conform to ANSI Z87. I standards.
4.b. Use suitable clothing made from durable flame-resistant
material to protect your skin and that of your helpers from
the arc rays.
4.c. Protect other nearby personnel with suitable, non-flammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
FUMES AND GASES
can be dangerous.
5.a. Welding may produce fumes and gases
hazardous to health. Avoid breathing these
fumes and gases. When welding, keep
your head out of the fume. Use enough
fumes and gases away from the breathing zone. When
welding with electrodes which require special
ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or
cadmium plated steel and other metals or coatings
which produce highly toxic fumes, keep exposure as
low as possible and within applicable OSHA PEL and
ACGIH TLV limits using local exhaust or mechanical
ventilation. In confined spaces or in some circumstances, outdoors, a respirator may be required.
Additional precautions are also required when welding
on galvanized steel.
5. b. The operation of welding fume control equipment is affected
by various factors including proper use and positioning of
the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker
exposure level should be checked upon installation and
periodically thereafter to be certain it is within applicable
OSHA PEL and ACGIH TLV limits.
5.c.
Do not weld in locations near chlorinated hydrocarbon
coming from degreasing, cleaning or spraying operations.
The heat and rays of the arc can react with solvent vapors

PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent
dans ce manuel aussi bien que les précautions de sûreté
générales suivantes:
Sûreté Pour Soudage A L’Arc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à l’électrode et à la piéce sont sous tension
quand la machine à souder est en marche. Eviter toujours
tout contact entre les parties sous tension et la peau nue
ou les vétements mouillés. Porter des gants secs et sans
trous pour isoler les mains.
b. Faire trés attention de bien s’isoler de la masse quand on
soude dans des endroits humides, ou sur un plancher
metallique ou des grilles metalliques, principalement dans
les positions assis ou couché pour lesquelles une
grande partie du corps peut être en contact avec la
masse.
c. Maintenir le porte-électrode, la pince de masse, le câble
de soudage et la machine à souder en bon et sûr état
defonctionnement.
d.Ne jamais plonger le porte-électrode dans l’eau pour le
refroidir.
e. Ne jamais toucher simultanément les parties sous tension
des porte-électrodes connectés à deux machines à souder parce que la tension entre les deux pinces peut être le
total de la tension à vide des deux machines.
f. Si on utilise la machine à souder comme une source de
courant pour soudage semi-automatique, ces precautions
pour le porte-électrode s’applicuent aussi au pistolet de
soudage.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où l’on pique le laitier.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque d’incendie dû aux étincelles.
7. Quand on ne soude pas, poser la pince à une endroit isolé de
la masse. Un court-circuit accidental peut provoquer un
échauffement et un risque d’incendie.
8. S’assurer que la masse est connectée le plus prés possible
de la zone de travail qu’il est pratique de le faire. Si on place
la masse sur la charpente de la construction ou d’autres
endroits éloignés de la zone de travail, on augmente le risque
de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits. Cela peut provoquer
des risques d’incendie ou d’echauffement des chaines et des
câbles jusqu’à ce qu’ils se rompent.
9. Assurer une ventilation suffisante dans la zone de soudage.
Ceci est particuliérement important pour le soudage de tôles
galvanisées plombées, ou cadmiées ou tout autre métal qui
produit des fumeés toxiques.
10. Ne pas souder en présence de vapeurs de chlore provenant
d’opérations de dégraissage, nettoyage ou pistolage. La
chaleur ou les rayons de l’arc peuvent réagir avec les
vapeurs du solvant pour produire du phosgéne (gas fortement toxique) ou autres produits irritants.
11. Pour obtenir de plus amples renseignements sur la sûreté,
voir le code “Code for safety in welding and cutting” CSA
Standard W 117.2-1974.
2. Dans le cas de travail au dessus du niveau du sol, se protéger contre les chutes dans le cas ou on recoit un choc. Ne
jamais enrouler le câble-électrode autour de n’importe quelle
partie du corps.
3. Un coup d’arc peut être plus sévère qu’un coup de soliel,
donc:
a. Utiliser un bon masque avec un verre filtrant approprié
ainsi qu’un verre blanc afin de se protéger les yeux du
rayonnement de l’arc et des projections quand on soude
ou quand on regarde l’arc.
b. Porter des vêtements convenables afin de protéger la
peau de soudeur et des aides contre le rayonnement de
l‘arc.
c. Protéger l’autre personnel travaillant à proximité au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de l’arc de
soudage. Se protéger avec des vêtements de protection
libres de l’huile, tels que les gants en cuir, chemise épaisse,
pantalons sans revers, et chaussures montantes.
PRÉCAUTIONS DE SÛRETÉ POUR
LES MACHINES À SOUDER À
TRANSFORMATEUR ET À
REDRESSEUR
1. Relier à la terre le chassis du poste conformement au code
de l’électricité et aux recommendations du fabricant. Le dispositif de montage ou la piece à souder doit être branché à
une bonne mise à la terre.
2. Autant que possible, I’installation et l’entretien du poste
seront effectués par un électricien qualifié.
3. Avant de faires des travaux à l’interieur de poste, la
debrancher à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

SAFETY
Electromagnetic Compatibility (EMC)
Conformance
Products displaying the CE mark are in conformity with European Community Council Directive of 3 May
1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility
(89/336/EEC). It was manufactured in conformity with a national standard that implements a harmonized
standard: EN 60974-10 Electromagnetic Compatibility (EMC) Product Standard for Arc Welding Equipment.
It is for use with other Lincoln Electric equipment. It is designed for industrial and professional use.
Introduction
All electrical equipment generates small amounts of electromagnetic emission. Electrical emission may be
transmitted through power lines or radiated through space, similar to a radio transmitter. When emissions
are received by other equipment, electrical interference may result. Electrical emissions may affect many
kinds of electrical equipment; other nearby welding equipment, radio and TV reception, numerical controlled
machines, telephone systems, computers, etc. Be aware that interference may result and extra precautions
may be required when a welding power source is used in a domestic establishment.
Installation and Use
The user is responsible for installing and using the welding equipment according to the manufacturer’s
instructions. If electromagnetic disturbances are detected then it shall be the responsibility of the user of the
welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases
this remedial action may be as simple as earthing (grounding) the welding circuit, see Note. In other cases it
could involve construction of an electromagnetic screen enclosing the power source and the work complete
with associated input filters. In all cases electromagnetic disturbances must be reduced to the point where
they are no longer troublesome.
vv
Note: The welding circuit may or may not be earthed for safety reasons according to national codes.
Changing the earthing arrangements should only be authorized by a person who is competent to access whether the changes will increase the risk of injury, e.g., by allowing parallel
welding current return paths which may damage the earth circuits of other equipment.
Assessment of Area
Before installing welding equipment the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account:
a) other supply cables, control cables, signaling and telephone cables; above, below and adjacent to the
welding equipment;
b) radio and television transmitters and receivers;
c) computer and other control equipment;
d) safety critical equipment, e.g., guarding of industrial equipment;
e) the health of the people around, e.g., the use of pacemakers and hearing aids;
f) equipment used for calibration or measurement
g) the immunity of other equipment in the environment. The user shall ensure that other equipment being
used in the environment is compatible. This may require additional protection measures;
h) the time of day that welding or other activities are to be carried out.
L10093 3-1-96H
SAFETY
Electromagnetic Compatibility (EMC)
The size of the surrounding area to be considered will depend on the structure of the building and other
activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.
Methods of Reducing Emissions
Mains Supply
Welding equipment should be connected to the mains supply according to the manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the mains
supply. Consideration should be given to shielding the supply cable of permanently installed welding equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The
shielding should be connected to the welding power source so that good electrical contact is maintained
between the conduit and the welding power source enclosure.
Maintenance of the Welding Equipment
The welding equipment should be routinely maintained according to the manufacturer’s recommendations.
All access and service doors and covers should be closed and properly fastened when the welding equipment is in operation. The welding equipment should not be modified in any way except for those changes
and adjustments covered in the manufacturers instructions. In particular, the spark gaps of arc striking and
stabilizing devices should be adjusted and maintained according to the manufacturer’s recommendations.
vivi
Welding Cables
The welding cables should be kept as short as possible and should be positioned close together, running at
or close to floor level.
Equipotential Bonding
Bonding of all metallic components in the welding installation and adjacent to it should be considered.
However, metallic components bonded to the work piece will increase the risk that the operator could
receive a shock by touching these metallic components and the electrode at the same time. The operator
should be insulated from all such bonded metallic components.
Earthing of the Workpiece
Where the workpiece is not bonded to earth for electrical safety, not connected to earth because of its size
and position, e.g., ships hull or building steelwork, a connection bonding the workpiece to earth may reduce
emissions in some, but not all instances. Care should be taken to prevent the earthing of the workpiece
increasing the risk of injury to users, or damage to other electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries
where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected
according to national regulations.
Screening and Shielding
Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire welding installation may be considered for special applications.

SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
• Only qualified personnel should
perform this installation.
• Turn the input power OFF at the disconnect switch or fuse box before working on
this equipment.
• Turn the Power switch on the DC-655
“OFF” before connecting or disconnecting output cables, wire feeder or remote
connections, or other equipment.
• Do not touch electrically hot parts.
• Always connect the Idealarc DC-655
grounding terminal (located on the welder
near the reconnect panel) to a good
electrical earth ground.
SELECT SUITABLE LOCATION
Place the welder where clean cooling air can freely
circulate in through the front louvers and out through
the rear louvers. Dirt, dust or any foreign material that
can be drawn into the welder should be kept at a
minimum. Failure to observe these precautions can
result in excessive operating temperatures and
nuisance shut-downs.

ELECTRICAL INPUT CONNECTIONS
Before installing the machine check that the input supply voltage, phase, and frequency are the same as the
voltage, phase, and frequency as specified on the
welder nameplate.
Use input wire sizes that meet local electrical codes or
see the Technical Specifications page in this manual.
Input power supply entry is through the hole in the
Case Back Assembly. See Figure A.1 for the location
of the machine’s input cable entry opening, Input
Contactor (CR1), and reconnect panel.
The DC-655 may be stacked three-high provided the
bottom machine is on a stable, hard, level surface. Be
sure that the two pins in the roof fit into the slots in the
base of the DC-655 above it.
TILTING
Do not place the machine on a surface that is inclined
enough to create a risk of the machine falling over.
ELECTROMAGNETIC COMPATIBILITY (EMC)
The EMC classification of the DC-655 is Industrial,
Scientific and Medical (ISM) group 2, class A.
The DC-655 is for industrial use only. (See prints
L10093-1, -2 safety pages in the Front of Instruction
Manual for further details).
Locate the DC-655 away from radio controlled
machinery. The normal operation of the DC-655 may
adversely affect the operation of RF controlled equipment, which may result in bodily injury or damage to
the equipment.
FUSE AND WIRE SIZES
Protect the input circuit with the super lag fuses or
delay type circuit breakers listed on the Technical
Specifications page of this manual for the machine
being used. They are also called inverse time or thermal/magnetic circuit breakers.
DO NOT use fuses or circuit breakers with a lower
amp rating than recommended. This can result in
“nuisance” tripping caused by inrush current even
when machine is not being used for welding at high
output currents.
GROUND CONNECTION
Ground the frame of the machine. A ground
terminal marked with the symbol ( ) is located inside
the case back of the machine near the input contactor.
Access to the input box assembly is at the upper rear
of the machine. See your local and national electrical
codes for proper grounding methods. Use grounding
wire sizes that meet local electrical codes or see the
Technical Specifications page in this manual.
