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.
