Then change the menu screen to the PRECHECK screen.
Record the measured value here as well.
Check the welding state, and repeat operations
9
to
⑮
to obtain an optimal result.
⑯
When welding is satisfactory, set the monitor value.
Change to the PRECHECK screen, and set
the precheck judgment range.
(Set the HIGH and LOW values so that the
optimal value will be in the center according to
the dispersion of the values measured in
⑮
.)
Lower the voltage when the peak current of precheck welding is flowing around the
current value set for CURRENT RANGE on the STATUS screen. Since the current is
also put a limit with the maximum current at the precheck welding, the precheck
welding will not be performed correctly.
⑰
Next, move to the COMPARATOR screen and set the upper and lower limit ranges of
the CURR, VOLT, and POWER.
(Set H at the maximum value and L at the minimum value when upper-lower limit
judgment is not desired.)
⑱
Conduct operations
9
to
⑰
for all schedule Nos. to use, and welding under multiple
conditions will be possible.
Record this value.
Set these values.
Set these values.
