Arc rays can burn eyes and skin − wear a welding helmet
with correct filter, and cover exposed skin with nonflam-
mable clothing.
Le rayonnement de l’arc peut provoquer des brûlures au
niveau des yeux ou de la peau – porter un casque protec-
teur muni d’un écran de filtre approprié et porter des vête-
ments non inflammables pour protéger toutes parties
exposées.

Fsafe3 2013-10
Welding sparks can cause fire or explosion. Move flam-
mables away. Do not weld on closed tanks or barrels, or
on containers that have held combustibles − they can
explode. Clean tanks or barrels properly.
Les étincelles de soudure peuvent provoquer un incendie
ou une explosion. Ne pas souder de cuves ou de ton-
neaux, au risque qu’ils explosent. Nettoyer soigneuse-
ment les cuves ou tonneaux.
Fsafe9 2018-01
Beware of electric shock from welding electrode or wiring.
Touching the electrode while in contact with the work or
ground can cause electric shock. Always wear dry
gloves. Keep all panels and covers closed.
Attention au risque d’électrocution due au contact avec
l’électrode de soudage ou les fils. Le fait de toucher
l’électrode tout en étant en contact avec la pièce ou la
terre peut provoquer une électrocution. Toujours porter
des gants secs. Tous les panneaux et couvercles doivent
rester fermés.
Fsafe6 2018-01
Breathing welding fumes and gases can harm your
health. Welding requires good ventilation. If ventilation is
impossible, such as when welding in a confined space,
use an air-supplied respirator.
L’inhalation des fumées et des gaz de soudure peut être
dangereuse pour la santé. Une bonne ventilation est
nécessaire pour procéder au soudage. S’il est impossible
de ventiler, dans des lieux confinés par exemple, utiliser
un respirateur à alimentation d’air.

3. Adjusting Amperage Or Voltage
. On some welding power
sources, the front panel output
control setting does not matter
and the Remote Hand Control
adjusts the full range of the
welding power source output.
