DPSW1-1: Starting mode
• 4-schedule mode: OFF
Inputting the starting input
I
,
II
,
III
or
IV
activates the
welding sequence corresponding to the input.
Set the conditions for each starting input in the
schedule mode.
• 15-schedule mode: ON
Welding sequence is selected by means of the
combination (binary code) of inputs of starting inputs
I
,
II
,
III
and
IV
.
With the 15-schedule mode, when the schedule
mode setting is completed, the following display
appears.

DPSW1-2: Control speed
This switch determines the control speed for the
secondary constant current control (when DPSW1-5
and DPSW1-6 are OFF).
Set this switch to OFF to one cycle response. Set
this switch to ON to 0.5 cycle response.
< Note >
• For
the primary CT with “Single-AC welding
machine”, set to OFF side. (one cycle).
• For the primary CT with single-phase DC welding
power source, set to ON side (0.5 cycle).

DPSW1-3: Trouble mode
This switch determines if the full wave detection is
treated in minor mode or major mode. (The other
troubles are treated in the major trouble mode.)
Set this switch to OFF for minor mode and ON for
major mode.

DPSW1-4: Self-holding
• Self-holding at the start of welding: OFF
If the starting input is turned off before the squeeze
time is completed, the solenoid valve is also turned
off.
• Self-holding at the start of sequence: ON
Self-holding starts at the same time as starting input
is accepted, and the welding sequence continues
even if the starting input is turned off.
To release self-holding state (in case of emergency),
set the DPSW1-9 to OFF side and connect the
emergency stop switch to the “Sequence stop/
current off” input terminal.

DPSW1-5: Compensating method
• Constant current compensation mode: OFF
In this mode, select either “Secondary toroidal coil”
or “Primary C.T.” for the “current detecting method
(DPSW1-6).
• Voltage compensation mode: ON
In this mode, the current is not monitored if the
toroidal coil or C.T is not used. The current is
monitored When the toroidal coil is used and the
DPSW1-6 is set to OFF (or when the C.T. is used
and the DPSW1-6 is set to ON), it monitors the
current and detects troubles, specifically the full
wave and no current state.

DPSW1-6: Current detecting method
• When this switch is set to OFF, the current is
detected by the secondary toroidal coil. Connect the
toroidal coil.
• When this switch is set to ON, the current is detected
by the primary C.T. Install and connect the specified
C.T.
