 Cold welding dies for SZ-3T( the dies on model SZ-3T and SZ-3TR are the same dimension):

 2.Cold welder Introduction:

1. Weld copper wire or aluminum wire; or weld copper wire with aluminum wire

2. No need any power, heat, only match corresponding dies.

3. Our machine can weld copper wire from 0.06mm-10.0mm; weld aluminum wire: from 0.06mm-15.0mm.

4. You can choose suitable machine according the wire diameter you need to weld and our machine's welding range.

5. For example, if you want to weld 0.90mm, 1.0mm, 1.20mm, 1.40mm copper wire, you can choose model SZ-3T, SZ-3TR. And also should match four single cavity dies or two double cavity dies.

6. Our machine is compatibility with other supplier’s welders. You can use others’ welding machine with our dies; or use our dies on other supplier’s machine.

7. The tolerance of dies to wire: -1%mm+ 3%mm wire to dies tolerance.

For example: 2.0mm dies can weld the wire diameter from: 1.98mm to 2.06mm wires.

8. Can different metals be welded using cold pressure? Cold welding can be used to join dissimilar materials, such as aluminum to copper.

9. The wire can be welded:
Naked copper wire & aluminum wire, brass wire; enameled copper wire, copper clad aluminum conductor; or weld copper wire & brass wire together with aluminum wire. Plastic wires and other wires should remove surface insulation part, then welding.

Cold welding can be used to join most non-ferrous wire and strip with diameters of between 0.08mm (.003145") and 25mm (.984") copper and 30mm (1.181") aluminum.

Cold welding can be used to join dissimilar materials, such as aluminum to copper. For example, transformer manufacturers have used PWM machines to weld copper rod terminations onto the end of the aluminum winding.

Steel wire or stranded wires can’t be welded.

Those wires can be welded:
