VR 7000 / VR 7000-11 / VR 7000-30 wirefeeder VR 7000 CMT wire-feed unit
The wirefeeders of the VR 7000 series are designed to be used with wirespools of max.
300 mm (11.81 in.) diameter.
The wirespool holder is located inside the wirefeeder housing. The wirespool is thus pro-
tected from soiling.
The standard 4 roller drive has good wire feeding properties. The VR 7000-series wirefeed-
ers are also suitable for use with long hosepacks.
Thanks to their compact overall design, the VR 7000 wirefeeders can be used in a wide
variety of different situations.
REQUIREMENTS The VR 7000 wirefeeders can be operated with the following power sources:
- TransSynergic 4000 / 5000 / 7200 / 9000
- TransPuls Synergic 3200 / 4000 / 5000 / 7200 / 9000
- TransPuls Synergic 2700 Duo
- TransPuls Synergic 2700 Duo TIG
The "CMT (Cold Metal Transfer)" welding process is only possible with the VR 7000 CMT
in conjunction with an appropriate CMT power source and CMT drive unit.
Application area - VR 7000: for all types of MIG/MAG welding
- VR 7000-11, VR 7000-30: primarily used with TS/TPS 7200 and TS/TPS 9000 high-
performance power sources
- VR 7000-11: also for flux core wire applications
- VR 7000 CMT: for "CMT" welding process, for all types of MIG/MAG welding
All variants of the VR 7000 are suitable for all standard shielding gases.
NOTE!
The VR 7000-11 and VR 7000-30 wirefeeders have a water-cooled electric motor with
shrunk-on-disc rotor, and may only be operated in conjunction with an appropriate
cooling unit.
