Easier setup and operation.
The SubArc Digital Series interface
controls recognize the power source
and wire drive connected, and
automatically configure the system
for proper operation. The easy-tounderstand interface provides the
operator with the necessary controls
to set process parameters and
control output. The power sources
feature simplified parallel and
tandem setups — just plug the cable
into the appropriate connectors.
SubArc Digital Series
Choice of three power sources, three interface controls
and a range of wire drive motors and accessories.
Digital process control technology.
Highly reliable thyristor power regulation.
Digital control and communication electronics
improve weld performance and simplify the
integration of the equipment in more advanced
applications.
Improved flux delivery system.
Our SubArc flux hopper utilizes a
flux valve mechanism that assures
continuous delivery of flux to the arc.
The unique valve design provides a
barrier between the flux and actuation
device to help prevent jamming of the
solenoid actuator due to dust and
debris. A sight glass is provided on
the front of the flux hopper allowing
the weld operator to visually monitor
the remaining flux in the hopper.
SubArc AC/DC Digital
SubArc DC 1000/1250 Digital

Easy to integrate.
Our SubArc power
sources are easy to
integrate by using
a standard Modbus® connection.
Different levels of integration are
possible, from simple remote
operation to more complex
automated systems.
Two DC power source models and one AC/DC power source model.
Power sources have sufficient power capacity to cover applications from
traditional DC single-arc to multi-wire tandem welding. In the case of
electroslag welding or other high-current demand, two or more power
sources can easily be paralleled (both DC and AC/DC machines).
Low-voltage accessory operation
and improved environmental
protection. The digital series
accessories are powered with
24 VAC control voltage from the
power source. All power sources,
interface controls and wire drives are
IP23 rated providing a high level of
protection for harsh environments.
All power sources also feature
thermal overload protection,
line voltage compensation and
Fan-On-Demand™.
Power source is warranted for three years, parts and labor.
Original main power rectifier parts are warranted for five years.

SubArc AC/DC Digital
SubArc AC/DC Digital and SubArc AC/DC 1250
Digital. AC welding output enables the SubArc
AC/DC to be used in tandem-arc welding systems
with a DC lead arc and AC trailing arc, or with
AC / AC arc combinations. Using multiple arcs
increases deposition rate, resulting in shorter
welding cycles for very thick weldments without
compromising quality. All AC balance control
modes can be set on the SubArc Interface Digital
or the SubArc Remote Pendant Digital. These
easy-to-understand interfaces include two
DC modes and 12 best-practice AC balance
settings. In multiple-arc configurations, the
system automatically adjusts the phase shifting
between power sources thereby eliminating arc
interaction. There is no need to employ a laptop
PC for complex wave shaping before operation.

SubArc System Parallel and Tandem Setups
Parallel Connections
DC or AC/DC controlling unit
Parallel setup. Only like power sources can
be paralleled. Paralleling of two machines to
increase maximum welding current is simply
done by connecting the paralleling cable from
RC2 on the first unit to RC1 on the second
unit. This works for both DC as well as AC/DC
machines. Daisy chaining multiple machines
to gain higher output is done in the same way.
No special tools, laptop or software needed...

Tandem setup. To use two or more AC arcs, the

to RC3 on the second unit. This automatically
sets the optimum phase shift for AC welding.
