①
CHARGE VOLTAGE
The charging voltage can be fixed.
The following voltages can be set: AUTO / 6 / 8 / 10 / 12 / 14 / 16 / 18 / 20 / 22
/ 24 / 26 / 28 / 30 V.
When AUTO is selected, the charging voltage is automatically set according to
the current range.
To maximize the performance of the equipment, keep the setting at AUTO
whenever possible.
②
CURRENT RANGE
This equipment permits selection of the current range according to the
magnitude of the welding current.
Model No.

③
SCHEDULE MODE
Switches between the 1-step and 2-step weld sequences.
When 2-step welding is unnecessary, select 1-step welding. Since there are
fewer items to be set for 1-step welding, this will make the screen display
easier to see.
SINGLE
1-step weld sequence
DOUBLE
2-step weld sequence
④
CONTROL
Selects the welding control method.
COMB.
Combination control of constant-current and
constant-voltage
The constant-voltage control method and the
constant-current-control method function simultaneously,
and priority is given to the control method with the lower set
value.
VOLT
Constant-voltage control
Controls so that the voltage detected by the V SENS cable
attached between electrodes will be the set voltage.
CURR
Constant-current control
Controls so that the welding current will be the set current.
⑤
START SIG. TIME
Sets the delay time between the input of the start signal and the start of the
weld sequence.
Under this setting, chattering of the start switch can be disregarded.
Select the set value from among 20 / 10 / 5 / 1 ms.
The delay time can be fully minimized when a non-chattering switch is used.
