PRÉCAUTIONS DE SÛRETÉ
Pour votre propre protection lire et observer toutes les instructions et les précautions de sûreté specifiques qui parraissent
dans ce m an uel auss i bien qu e les précaution s de sû re té
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 positio ns assis ou couch é p our lesquelles une
grand e partie du corps peut êtr e en con tact 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 r ay on s de l’ ar c peuvent r éa gi r 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. Proté ger l’autr e personne l travaill ant à proximi té au
soudage à l’aide d’écrans appropriés et non-inflammables.
4. Des go uttes 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. Ava nt de fair es d e s tr avau x à l’ int eri e ur d e pos te, l a
debrancher à l’interrupteur à la boite de fusibles.
4. Garder tous les couvercles et dispositifs de sûreté à leur
place.

WELDING CABLE CONNECTIONS
Cable Size and Length
Be sure to use welding cables that are large enough.
The correct size and length becomes especially
important when you are welding at a distance from
the welder.
Table A.1 lists recommended cable sizes and lengths
for rated current and duty cycle. Length refers to the
distance from the welder to the work and back to the
welder. Cable diameters are increased for long cable
lengths to reduce voltage drops.

Cable Installation
Install the welding cables to your BULLDOG™ 140 as
follows. See Figure A.1 for the location of parts.
1. The gasoline engine must be OFF to install welding cables.
2. Remove the 1/2 - 13 flanged nuts from the output
terminals.
3. Connect the electrode holder and work cables to
the weld output terminals. You can connect either
cable to either terminal, since the BULLDOG™
140 provides AC weld current.
4. Tighten the flanged nuts securely.
5. Be certain that the metal piece you are welding
(the “work”) is securely connected to the work
clamp and cable.
6. Check and tighten the connections periodically.
CAUTION
• Loose connections will cause the output termi-
nals to overheat. The terminals may eventually
melt.
• Do not cross the welding cables at the output
terminal connection. Keep the cables isolated
and separate from one another.

Lincoln Electric offers a welding accessory kit with
the properly spe cified welding ca bles. See the
ACCESSORIES section of this manual for more information.
ELECTRICAL CONNECTIONS
MACHINE GROUNDING
Because this portable engine driven welder creates its
own power, it is not necessary to connect its frame to
an earth ground, unless the machine is connected to
premises wiring (home, shop, etc.)
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:
WARNING
1. Be grounded to the frame of the welder using a
grounded type plug.
2. Be double insulated.
Do not ground the machine to a pipe that carries
explosive or combustible material.
-----------------------------------------------------------------------
When the BULLDOG™ 140 is mounted on a truck or
a trailer, the machine generator ground stud MUST
be securely connected to the metal frame of the vehicle. See Figure A.1. The ground stud is marked with
the symbol .
PLUGS AND HAND-HELD EQUIPMENT
For further protection against electric shock, any
electrical equipment connected to the generator
receptacles must use a three-blade, grounded type
plug or an Underwriter’s Laboratories (UL) approved
double insulation system with a two-blade plug.
Ground fault protection is recommended for hand
held equipment.
WARNING
Never operate this machine with dama ged or
defective cords. All electrical equipment must be
in safe condition.
-----------------------------------------------------------
AUXILIARY POWER RECEPTACLES
The control panel of the BULLDOG™ 140 features
two auxiliary power receptacles:
• A 20 amp, 120 volt duplex (double outlet) recepta-
cle
• A 20 amp 240 volt simplex (single outlet) recepta-
cle.
See Figure A.1.
Through these receptacles the machine can supply
up to 4,000 rated continuous watts and 5,500 surge
watts of single-phase AC power.

PREMISES WIRING
The B ULLDOG™ 1 4 0 is not rec o m m e n ded fo r
premises wiring.
The BULLDOG™ 140 does not have a combined
120/240 volt receptacle and cannot be connected to
a premises as described in other Lincoln literature.
Remember that the BULLDOG™ 140 is intended only
for backup, intermittent use power.
Certain electrical devices cannot be powered by the
BULL D OG™ 1 4 0. R e fer t o Tabl e A.2 for these
devices.
CIRCUIT BREAKERS
Auxiliary power is protected by circuit breakers.
When the machine is operated in high temperature
environments, the breakers may tend to trip at lower
loads than normally.
CAUTION
A-6
Never bypass the circuit breakers. Without overload protection, the BULLDOG™ 140 could overheat and/or cause damage to the equipment being
used.
