single cavity welding dies are matched to DA100, DB100 cold welding machines.

The range of copper wire: 1.00mm--3.25mm

The range of aluminium wire: 1.00mm--5.00mm.

double cavity welding dies are matched to DA100, DB100 cold pressure welding machines.

The range of copper/aluminium wire: 1.00mm--2.50mm.

Remark: The range of rectangular non-ferrous wire is calculated according to the cross section area.
