CHAPTER 1: SYSTEM DESCRIPTION
IS-300CA INVERTER POWER SUPPLY
1-2 990-418

The welding frequency can be adjusted from 600-3000Hz in 100 Hz steps in each schedule for the
Basic unit, and 600-1000Hz for the Advanced / EtherNet/IP
TM
unit. Higher frequencies aid in the
welding of finer applications. Please match the frequency of the welder to the transformer.

Comes equipped with a current-shutoff function, which shuts off current in response to external input
(e.g., displacement of the electrode) for WELD1 to WELD3 respectively, ensuring stable fusing.

Use of an inverter allows for high power factor and stable power conditions.

Easy setting of a variety of items through the menu selection system.

Applicable to inverter transformers manufactured by various companies by changing the frequency
(600Hz to 3000Hz in units of 100Hz for
Basic , 600Hz to 1000Hz for Advanced / EtherNet/IP
TM
).

Seven protective functions for maximum ease of operation:

No-current / no-voltage
 Over current
 Temperature
 Self diagnostics
 Grounding error

Load short error
 Phase error

RS-232 communications standard, RS-485 optional.
Advanced Models Only

The analog output terminal (voltage output proportional to force) for electro-pneumatic proportional
valve and the analog input terminal (voltage input proportional to force) for force measurement have
two channels, respectively.

Welding can be stopped at the set displacement by connecting the displacement gauge and measuring
the displacement produced in fusing.
