General

Device concept

VR 7000 / VR 7000-11 / VR 7000-30 wirefeeder
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 protected from soiling.
The standard 4 roller drive has good wire feeding properties. The VR 7000-series
wirefeeders 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.
REQUIRE-
The VR 7000 wirefeeders can be operated with the following power sources:
MENTS -
-
-
-
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.
