CHAPTER 1
SYSTEM DESCRIPTION
Section I: Features
Basic and Advanced Units
The AMADA WELD TECH IS-2200CA/4500CA is an inverter-type power supply specially designed to
be used for spot welding and fusing. The AMADA WELD TECH IS-2200CA/4500CA 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.
•
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.
•
The welding frequency can be adjusted from 600-1000Hz in 100 Hz steps in each schedule. 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 1000Hz in units of 100Hz).
