BRAZING SPARKS can
cause fire or explosion.
6.a.
Remove fire hazards from the brazing area.
If this is not possible, cover them to prevent
the sparks from starting a fire Remember
that brazing sparks and hot materials from
brazing and soldering can easily go through
small cracks and openings to adjacent
areas. Avoid working near hydraulic lines.
Have a fire extinguisher readily available.
6.b. Where compressed gases are to be used at the job site,
special precautions should be used to prevent hazardous
situations. Refer to “Safety in Welding and Cutting” (ANSI
Standard Z49.1) and the operating information for the
equipment being used.
6.c. Do not heat, cut or braze tanks, drums or containers until
proper steps have been taken to insure that such proce-
the
dures
will not cause flammable or toxic vapors from substances inside. They can cause an explosion even
they have been “cleaned”. For information, purchase
“Recommended Safe Practices for the
Welding and Cutting of Containers and Piping That Have
Held Hazardous Substances”, AWS F4.1 from the American

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 LʼArc
1. Protegez-vous contre la secousse électrique:
a. Les circuits à lʼélectrode 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 sʼisoler de la masse quand on
soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans l e s
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 lʼeau 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 sʼapplicuent aussi au pistolet de
soudage.
6. Eloigner les matériaux inflammables ou les recouvrir afin de
prévenir tout risque dʼincendie dû aux étincelles.
7. Quandonnesoude pas, poser la pince à une endroit isolé de la
masse. Un court-circuit accidental peut provoquer un échauffement et un risque dʼincendie.
8. Sʼassurer que la masse est connectée le plus prés possible de la
zone de travail quʼil est pratique de le faire. Si on place la masse
sur la charpente de la construction ou dʼautres 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 dʼincendie ou
dʼechauffement des chaines et des câbles jusquʼà ce quʼils 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
dʼopérations de dégraissage, nettoyage ou pistolage. La chaleur
ou les rayons de lʼarc 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 nʼimporte quelle partie du
corps.
3. Un coup dʼarc peut être plus sévère quʼun coup de soliel, donc:
a. Utiliser un bon masque avec un verre filtrant approprié ainsi
quʼun verre blanc afin de se protéger les yeux du rayonnement de lʼarc et des projections quand on soude ou quand
on regarde lʼarc.
b. Porter des vêtements convenables afin de protéger la peau
de soudeur et des aides contre le rayonnement de lʻarc.
c. Protéger lʼautre personnel travaillant à proximité au soudage
à lʼaide dʼécrans appropriés et non-inflammables.
4. Des gouttes de laitier en fusion sont émises de lʼarc de soudage.
Se protéger avec des vêtements de protection libres de lʼhuile,
tels que les gants en cuir, chemise épaisse, pantalons sans
revers, et chaussures montantes.
5. Toujours porter des lunettes de sécurité dans la zone de
soudage. Utiliser des lunettes avec écrans lateraux dans les
zones où lʼon pique le laitier.

will distort the brazing wire. Too little pressure
allows the drive rolls to slip. Most brazing wires
feed best with the pressure arm set between 2
and 4.
Holds the spool in place. Remove by squeezing
the steel piece.
Used to set moderate friction to keep the spool
from unwinding.
Holds the gun in place.
