SYSTEM DESCRIPTION

Section I: Features

Basic, Advanced and EtherNet/IP

Models

The Amada Weld Tech IS-300CA is an inverter-type power supply specially designed to be used for spot

welding and fusing. The IS-300CA provides 300 amps primary current.

The IS-300CA can be ordered as a Basic (1-325-02 / 1-325-02-01) or Advanced (1-325-02-02 / 1-325-

02-03) or EtherNet/IP

(1-325-02-04 / 1-325-02-05) units. The feature differences are highlighted

below and throughout the manual. For the rest of this manual, the Amada Weld Tech IS-300CA will

simply be referred to as the Power Supply, unless a feature or procedure unique to a specific model is

described.

You program and monitor Power Supply operation by using the external MA-660A Program Unit which

is sold separately. This Program Unit is commonly referred to as “the Pendant.” For the rest of this

manual the MA-660A will simply be referred to as the Pendant.

 The power supply accepts 3-phase voltage from 380VAC to 480VAC or 200VAC to 240VAC.

 Welding-current monitoring function for judgment of weld quality.

 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. The control method can be set for WELD1 to WELD3, respectively.

 Pulse and upslope (downslope) can be set for WELD1 to WELD3, respectively.
