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.
Easy to integrate. Our
SubArc power sources are
easy to integrate by using
a standard Modbus
®
connection.
All power sources also
feature thermal overload
protection, line voltage
compensation and
Fan-On-Demand.
