System Overview
The Power Wave ® AC/DC 1000 ® SD power source is
designed to be a part of a modular welding system
typically controlled by a MAXsa™ 10 Controller or a
customer supplied Programmable Logic Controller
(PLC). Each welding arc may be driven by a single
power source or by a number of power sources
connected in parallel. The actual number of power
sources per arc will vary depending on the application.
When only one power source is required for an arc
group, it must be configured as a Master. When
parallel machines are required, one is designated as
the Master and the rest as Slaves. The synchronizing
connectors for paralleled machines are on the back of
the power source. The Master controls the AC
switching for the arc group, and the Slaves respond
accordingly. See Figure A.3.
When employed in a multi-arc AC system the arcs
must be synchronized to each other. The Master for
each arc can be configured to follow a dedicated
external synchronization signal to determine its
frequency and balance. The Synchronizing
Connectors on the back of the Power Wave
® AC/DC
1000 ® SD provide the means to synchronize the AC
wave shapes of up to six different arcs to a common
carrier frequency. (See Figure A.3). This frequency
can range from 20 hertz to 100 hertz. It can also
control the phase angle between arcs to reduce the
effects of welding related issues such as "Arc Blow".
