Specifications
(1) Product Specifications
(Items in can be set for each schedule.)
Power supply
Single-phase, 100 V AC-10% to 120 V AC +10% or 200 V AC-10% to
240 V AC +10% (50/60 Hz)
The voltage is cannot be selected. (Fixed on shipment.)
Control method
Switching control by transistor
The basic frequency is 125 kHz, and the frequency is 1/integer of it.
Maximum is 125 kHz (frequency is variable automatically).
Welding current
control
Constant-current
control method
Controls so that the welding current will be the
set current.
Constant-voltage
control method
Controls so that the voltage detected by the V
SENS cable attached between electrodes will be
the set voltage.
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 whichever reaches the set value.
