Power-Up Sequence
When power is applied to the Power Wave
®
AC/DC
1000 SD CE, the status lights will flash green for up to
60 seconds. During this time the Power Wave
®
AC/DC
1000 SD CE is performing a self test, and mapping
(identifying) each component in the local ArcLink
system. The status lights will also flash green as a result
of a system reset or configuration change during
operation. When the status lights become steady green
the system is ready for use.
Common Welding Procedures
Making a weld
The serviceability of a product or structure utilizing
the welding programs is and must be the sole
responsibility of the builder/user. Many variables
beyond the control of The Lincoln Electric Company
affect the results obtained in applying these
programs. These variables include, but are not
limited to, welding procedure, plate chemistry and
temperature, weldment design, fabrication methods
and service requirements. The available range of a
welding program may not be suitable for all
applications, and the build/user is and must be
solely responsible for welding program selection.
The steps for operating the Power Wave
®
AC/DC 1000
SD CE will vary depending upon the user interface of the
welding system. The flexibility of the system lets the user
customize operation for the best performance.
Consult the User Interface documentation for more
detailed set up information. (MAXsa™ 10, Command
Center, PLC, Robot etc..)
First , consider the desired welding procedures and the
part to be welded. Choose an electrode material,
diameter, and flux.
Second , find the program in the welding software that
best matches the desired welding process. The standard
software shipped with the Power Wave
®
AC/DC 1000
SD CE encompasses a wide range of common
processes and will meet most needs. If a special welding
program is desired, contact the local Lincoln Electric
sales representative.
To make a weld, the Power Wave
®
AC/DC 1000 SD CE
needs to know the desired welding parameters.
Waveform Control Technology™ allows full
customization of Strike, Run-in, Crater and other
parameters for exacting performance.
Overview of the AC/DC Submerged Arc
Process
The Power Wave
®
AC/DC 1000 SD CE combines the
advantages of AC and DC Submerged Arc Welding
(SAW) into a single power source. The limiting factor of
AC-SAW welding has traditionally been the time it takes
to transition from positive to negative polarity. This lag
through the zero crossing can cause arc instability,
penetration, and deposition problems in certain
applications. The Power Wave
®
AC/DC 1000 SD CE
utilizes the speed of an inverter based power source,
and the flexibility of Waveform Control Technology™ to
address this issue.
By adjusting the Frequency, Wave Balance and Offset of
the AC waveform the operator can now control the
balance (relationship) between the penetration of DC
positive and the deposition of DC negative while taking
full advantage of the reduction in arc blow associated
with AC.
Output waveform variations made possible by Waveform
Control Technology™
Depending on the process, different parts of the output
waveform abd wire feed speed may be modulated at
varying rates to achive a smooth and stable arc.
Multiple Arc System Consideration
Large scale SAW applications often employ multiple arcs
to increase deposition rates. In multiple arc systems,
magnetic forces created by like and opposing weld
currents of adjacent arcs can result in arc interaction that
can physically push or pull the arc columns together.
See Figure below. To counteract this effect, the phase
relationship between adjacent arcs can be set to
alternate and equalize the duration of magnetic push
and pull forces. This is accomplished through the
synchronizing cables (K1785-xx). Ideally, the net result
