3-4 990-412
SQD / Squeeze delay time
Length of time added to SQZ; only for the first weld after start
signal in repeat operation
SQZ / Squeeze time Length of time until proper squeeze is applied to workpiece
COOL1
/ Cooling time 1 and
COOL2
/ Cooling time 2
Length of time to cool workpiece after turning off welding
current
HOLD
/ Hold time
Length of time to hold workpiece after turning off welding
current
OFF
/ Off time (*)
Length of time to turn off valve signal between repeated
operations
(No repeat operation if set to "0" or the upper/lower limit
judgment error occurs in a sequence.)
* OFF/Off time
•
Count and step value are updated each welding.
•
RE-WELD
does not work simultaneously with
OFF
. When
OFF
is set,
RE-WELD
becomes invalid.
•
START SIG.MODE
has limitations. When OFF is set,
MAINTAINED
of
START
SIG.MODE does not work. It works as LATCHED .
c. WELD (1, 2, 3)
Set the length of time to allow welding current to flow. As units of time, ms and CYC may be selected.
Either unit can be selected via the MODE SELECT screen.
UP (1, 2, 3)
Set the upslope time (to increase the welding current gradually).
DOWN (1, 2, 3)
Set the downslope time (to decrease the welding current gradually).
NOTE: Upslope / Downslope waveform when COOL (cooling time) is set to 0.The welding
current normally increases from the UF set value to the HEAT set value and decreases from the
HEAT set value to the UF set value, but E-10 (Schedule setting error) will occur when the Power
Supply starts with the following setting.
When the control methods for the previous and subsequent stages in the multi-stage welding are
changed. The control method for the previous stage is different from that for the subsequent
stage.
When the upslope time is set for the subsequent stage in the multi-stage welding, the upslope
time is set for the subsequent stage, and the
HEAT
setting of
D
and the
UF HEAT
setting of
E
are different.
