General
Product concept
The VR 4000 Yard wire-feed unit with four-roll drives is designed to be used with wire-
spools with a diameter of up to 300 mm.
The Yard wire-feed unit was specifically developed for use in shipyards and in the
offshore industry. The ergonomic housing is constructed from powder-coated aluminium
sheets. These panels not only weigh very little, but they are also extremely robust and
resistant to corrosion.
The sealed design of the VR 4000 Yard ensures the best possible protection against
dust and other impurities affecting the wirespool.
Further properties of the Yard wire-feed unit are its suitability for use in inspection
openings and the ability to use the unit even when it is lying on its side.
In addition to its considerable practicality, the Yard wire-feed unit is also extremely well
suited for use with very long hosepacks.
The Yard wire-feed unit can be used with all standard protective gas shields.
The VR 4000 Yard is available with a Fronius / Dinse / Euro torch connection.
The Yard wire-feed unit is particularly suitable for use with self-shielding flux core wires.
As these are mostly used with gascooled welding torches, VR 4000 Yard has no stan-
dard water connections due to weight considerations.
Gascooled welding torches have also been tried and tested with a basic flux core wire
of 1.2 mm (.047 in.).
