<Note>
In case of using this product to a single-phase AC
welding machine with the primary C.T., set the
“DPSW1-2” to the OFF (1 cycle) side.
（ 7 ） DPSW1-7: Tip stick detection
When this switch is set to ON, the tip stick detection
is turned ON. When the SOL output is turned OFF by
the completion of welding, SCR is ignited (at an
angle of 130°) after 20 cycles (approx. 0.4 sec.) to
check if the upper/lower electrodes and the work are
stuck. (If tips are stuck, current flows.)
（ 8 ） DPSW1-8: Re-welding
When this switch is set to ON and the current lower
limit is set (to be set by customers), if welding current
below the lower limit flows, after the holding time
ends, the sequence is started with the up-slope time
to re-weld after 10 cycles while keeping the SOL
output ON. However, the re-winding can be
performed only once.
（ 9 ） DPSW1-9: Current off selection
• In case this switch is set to OFF, when the
“Sequence stop/Current off” input terminals are
open, the sequence stops and the “Trouble output”
outputs.
• In case this switch is set to ON, when the
“Sequence stop/Current off” input terminals are
open, it goes in “current off” state while keeping the
sequence run as usual.

DPSW1-10: Current incremental method
• When this switch is set to OFF (Step-up mode), the
welding is performed while increasing the welding
current by the preset incremental rate at every
welding point.
• When this switch is set to ON (Signal-up mode), the
welding is performed while increasing the welding
current by the preset incremental rate at every step-
up input.

Functions to be set by DPSW2
（ 1 ） DPSW2-1:Pressure control
Set this switch to ON when the proportional control
valve (optional) is applied.
* In such ase, it is necessary to use pressure control
unit (YX-ZZ025) (optional).
（ 2 ） DPSW2-2: Checking
Make sure to keep this switch OFF. It is the switch for
manufacturer’s checking.
（ 3 ） DPSW2-3: Counter
This switch determines the counting method for
welding counter and production counter. Set this
switch to OFF to additive method, which displays
accumulated welding/production count at the start of
operation. Set this switch to ON to subtractive
method, which displays remaining welding/
production count at the start of operation.
7.3
Welding counter and Production counter
（ 1 ） In the setting mode, set the SOL No., and then set
welding count and number of products.
(The welding count and the number of products can
be set for SOL
I
and SOL
II
separately.)
（
2
）
Press “RUN” key and press the “ENTER/SHIFT” key
twice, then the welding count and the number of
products are displayed on the data indicators A and
B.
（ 3 ） After that, every time welding is performed, the
welding counter is increased by 1.
When the welding counter reaches the preset value,
the welding counter completion output is turned on,
the “COUNT UP” lamp of the “WELD CNTR.
(MONITOR)” lights, and the buzzer sounds.
（

）
At the same time (when the welding counter
completion output is turned on), the production
counter is increased by 1.
When the production counter reaches the preset
value, the production counter completion output is
turned on, the “COUNT UP” lamp of the “PROD.
CNTR. (MONITOR)” lights, and the buzzer sounds.
