Parameters for short - cycle procedure
The following parameters are only starting points (
guide values
) which must
be adjusted to specific application conditions (base material, work piece
surface condition, weld position, gun type, weld circuit inductance and
grounding etc.). It is recommended to perform weld robustness test (current-
time tolerance graph) using the values below as center points to determine
optimum welding parameters for the application.
