Easy to integrate. Our
SubArc power sources are
easy to integrate by using
a standard Modbus®
connection.
SubArc AC/DC
1250 Digital
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).
All power sources also
feature thermal overload
protection, line voltage
compensation and
Fan-On-Demand.™
