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 appropriate-
ness of all parameters and settings should be evaluated and modified by the end user as necessary based upon application-specific require-
ments. 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 warran-
ties including any implied warranty of fitness for a particular purpose.
