Signal-up
It is a function to increase the welding current at the
preset current incremental rate every time the “Step-up
shift” input is given.
This sequence is completed when the welding current
reaches or exceeds the maximum current.
（
1
）
Set the DIP switch DPSW1-10 to ON (selecting
“Signal-up”).
（
2
）
In the setting mode, set the SOL No., and then set
the current incremental rate. (The set-up conditions
can be set for SOL
I
and SOL
II
separately.)
（ 3 ） Press “RUN” key and press the “ENTER/SHIFT” key
three times, then the current accumulated current
incremental rate is displayed.
（ 4 ） When the welding current (based on the
accumulated current incremental rate) reaches or
exceeds the preset maximum current, the “Signal-up
completion output” (the same output as that for the
step-up completion) is turned on, the “COUNT UP”
lamp of the “STEP-UP CNTR. (MONITOR)” lights,
and the buzzer sounds.
• After that, even if the “step-up shift” input is turned
on, the input is ignored and the operation is
continued at the maximum current while maintaining
the output.
（ 5 ） If the set value for they current incremental rate is
changed, during the operation, the newly set
incremental rate is added to the current accumulated
current incremental rate.
