2. Features
The Miyachi Technos FINE SPOT-INVERTER
IS-120B
is an inverter-type power supply,
large in capacity and specially designed to be used for spot welding and fusing. (*)
In addition, it is small in size and convenient to move or shift. Monitor function is
provided, which enables judging defective or non-defective welding.
Has a welding current monitoring function for judgment of the weld quality.
Has six control systems
(
Primary constant-current effective value control,
secondary constant-current effective value control, secondary constant-power
effective value control, primary constant-current peak value control, secondary
constant-voltage effective value control and constant-phase control
)
for stable
weld quality.
Has an interrupting function
([
INTERRUPT
])
to interrupt fusing current by
externally inputting a displacement of the electrode, etc., for stable fusing.
Since an inverter is used, the power factor is high and the power condition is
stabilized.
Various items can be set easily by the menu selection system.
Applicable to inverter transformers manufactured by various companies by
changing the frequency
(
600Hz/800Hz/1000Hz
)
.
With four protective functions, the operator can work at his/her ease.
・
Overcurrent detecting function
・
No-current / no-voltage detecting function
・
Thermostat fault detecting function
・
Self diagnostics
Small and light, but having a capacity rating of 48kVA
(
at 440VAC input
)
and
maximum setting of 20kA.
(*)
IS-120B
has three types,
IS-120B-00,
IS-120B-02
and
IS-120B-03
