SZ-158 single phase arc welding machine/cold welding machine

Remarks:
1.No need of heat or electricity and some form of flux to make the joins of wire.
2.It is possible to weld two different diameter wire with different material together.
3. Automatically operated. Simple and convenient. Solid rod can also be welded.
4.It is electric/hydraulic powered machines capable of welding large round wire and strip materials. Caster mounting provides ease of movement in work area.
5. Widely used in the cold welding for the wire of copper, aluminum, gold, silver, nickel, and other non-ferrous metal wire/rod.

All welding machines should match welding dies in welding:
Each wire size should match a die.
Dies net weight in SZ-158: 5.5KG

2. 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.

3. Brief description of cable cold pressure welding machine:
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.
Those wires can be welded: 

Application of cable industry:

4.Main benefits of using cold welding:
The weld cycle takes only seconds to complete and creates a permanent bond stronger than the parent material, without using heat, fillers or fluxes.
The welding part is stronger than original part, which can do drawing again.

After welding effect and test(8.0mm wires as follow):

5. Advantage of Our cold welder:
*One year quality guarantee for main welding Machine. Lifetime Maintenance.
*Competitive price.
*Flexible delivery for sample and big order. Usually most not quite big orders can be delivered within 3 working days after order confirmed.
*10 years working experience for production & Research and Development.
* Certificate: CE, CCC, ISO9001-2008; exporting entitlement.
* Agents & distributors & representatives are welcome for all countries.

6. Delivery:
*For small order, we recommend by express like DHL, FedEx, UPS, etc. Large order by air, by sea, by train.
*All welders are in stock, only need time to make welding dies.

7. Exporting Countries we have:
We had exported many countries with good result, like South Korea, India, Pakistan, Sri Lanka, Indonesia, Malaysia, Singapore, Philippines, Vietnam, Thailand, Australia, Iran, UAE, Saudi Arabia, Turkey, Kazakhstan, Uzbekistan, USA, Canada, Russia, Finland, Germany, Serbia, Slovakia, Romania, Egypt, South Africa, Morocco, Tanzania, Angola, Brazil, Mexico, Argentina, Chile, Colombia, etc.

8. Welding process:
1. Adjust the machine:

2. Thread the wires into the dies:

3. Welding the wire, from the centre holes, we can see two wires terminal are joined together:

4. Take out the welded wires, then clean the flash:
