    Detailed features

    1. Precise 4-roller gear with 4 motorized wire feeder rollers. Wire feed speed 0.5 – 25 m/min (modelDV-26) or high performance drive 0.5- 30 m/min(model DV-31).

    2. Big wire feeder rings allow a constant wire feed speed at a low pressure. 2 grooves respectively for 2 different wire diameters.

    3. Change of the wire feeder rings without any tools.

    4. Easy wire insertion due to superb accessibility and snap lock mechanism.

    5. Dust-tight drive motor with tacho guarantees a constant wire feed speed (DV-31).

    6. Euro torch connection as standard.

    7. Pressure adjustment of both rollers.

    8. Wire straightening device for perfect and constant wire feeding (DV-31).

    9. Cut away side panels facilitate easy insertion of the wire spool.

    10. Gas hoses, water hoses and all cables are protected from environmental damage due to a unique closed case design.

    11. Consumables and spare part identification chart attached as standard.

    12. 2 x 4 rubber feet ensure operation in both, vertical and horizontal position.

    Double wire feeder DV-26 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.

    Easy to mount, universal in action.

    Standard horizontal mounting.
    Vertical mounting of the wire feeder can be achieved in seconds.
