SubArc Digital Series

SubArc DC Series

is DC only.

See literature ADM/10.0 UK

The SubArc Digital Series of power sources, interface controls and accessories include digital

control and communication electronics designed to improve weld performance and simplify the

integration of the equipment in more advanced applications.

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

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.™
