Double wire feeder DV­26 TWIN

Two different wires should be welded with the same machine? The annoying changing of the wire and the torch is no longer required with the double wire feeder DV-26 TWIN. Two different programs can be selected, the machine switches automatically to the selected torch by pressing the torch trigger. As an option the operation panel can be integrated in the wire feeder.A wheeled version is also available.

Standard Euro connector, no further control cables are necessary.

The multi-coloured LED shows the selected energy.

Precise energy control is realized through the slide switch mounted on the top of the torch handle before, during and after the welding process. The present conditions are shown through the stepless multi-coloured LED display mounted on the top of the torch handle.

With the slide switch free selectable operating points can be recalled. All settings can be adjusted on the existing welding characteristics. Perfectly reproducible welding results in every adjustment.
