weld table
The following Stud Expert weld table is programmed into the welder
control system. It provides automatic weld settings, based on stud type
and diameter.
There are conditions that will filter the table for selection, or reveal only a
subset of the table to the user.
• In the case of the N1500i, studs requiring more than 1500A of
weld current will not appear in the list for selection.
• Input Power - If the maximum current on the N1500i is limited
to 800A due to single phase input power, studs requiring >800A
will not display in the list.
