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.

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. Information About Default Weld Parameters And Settings
NOTICE − Each welding application is unique. Although certain Miller Electric products are designed to determine and default to certain typical welding
parameters and settings based upon specific and relatively limited application variables input by the end user, such default settings are for reference
purposes only; and final weld results can be affected by other variables and application-specific circumstances. The appropriateness of all parameters
and settings should be evaluated and modified by the end user as necessary based upon application-specific requirements. The end user is solely
responsible for selection and coordination of appropriate equipment, adoption or adjustment of default weld parameters and settings, and ultimate
quality and durability of all resultant welds. Miller Electric expressly disclaims any and all implied warranties including any implied warranty of fitness
for a particular purpose.
