SZ-3TR cable and wire welding machine China factory price

2. Brief description:
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. It should make 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. It can weld following wires: copper wire ( purple copper wire, brass wire, including round wire or flat wire, square wire); aluminum wire. Plastic wire and other wires should remove surface insulation part, then welding.

Steel wire can't be welded.

3. Principle of cold welding:
Cold-pressure welding is a method of connecting metal and alloy by exerting pressure instead of using electricity, heat, fillers and fluxes. Under concentrated pressure, surface area of both contact surfaces expanded, thus cracking the original protective layer that hampering welding, and outer force enable close connection of exposed pure metal basis, hence generating new atomic combination, and welding is realized by continuously increasing force.
