Audited Supplier Product Description
Intermediate Frequency Inverter DC Spot (Convex) Welder
Medium Frequency DC Welding Machine, MFDC Welder, Spot Welding Machine, Projection welding machine. With CE/CCC/ISO certificate.
Description:
Product highlights: Energy saving, power saving, high efficiency, low operating cost, high welding quality.
Product overview: The Medium frequency inverter DC spot ( convex ) welding machine converts the power frequency (50 Hz) AC to the intermediate frequency (1000 Hz) DC output, the time resolution is higher than the power frequency, the control accuracy is also improved, and the output current is not affected by the secondary output circuit change, the thermal efficiency is higher, the output power is great, and the welding quality is better. Compared with the traditional power frequency welding machine, inverse medium frequency DC welding will be highly efficient and energy-saving, which is a technological revolution breakthrough in the field of resistance welding.
Welding material: Aluminum, copper, galvanized sheet, carbon steel, nikel, tungsten and other metal materials.
Material thickness: < 5mm
Process recommendation: Spot welding
Application industry: Widely used in welding of metal products in automobile and auto parts manufacturing, new energy power battery, photoelectric communication, Electric light, compressor, hardware, furniture, kitchenware and other industries

Feature
1. Energy Saving: Compare with using low frequency, it can help to reduce the consumption of electric energy. The transformer of the same weight could output more energy. It can also be conveniently used with the large automatic welding clamp.
2. In a semi-automatic machine, one medium frequency transformer can replace many low frequency transformers which can help to reduce the parallel connection in secondary circuit.
3. Improve the power factor, reduce the production cost.
4. Reduce interference in secondary circuit which is in the large open area: the welding current is direct current. When there is induction or magnetic material in secondary winding, the welding will not be affected.
5. More adaptable to the fluctuation of power grid and voltage drop: a part of the energy has been stored by inverter and been supplied to load. It replaces the way of power supply to load directly from the power grid.
6. More precise and fast control of current: Compare with low frequency system, it is able to analyze more parameters in a more precise way.
7. The technology of MF system is more traditional and reliable which can prevent the damage results from the breakdown of silicon controlled.
8. Reduce operation cost, including saving the energy of each spot welding and reducing the cycle of welding.
Application
Especially suitable for aluminum, copper, galvanized sheet, carbon steel, nickel, tungsten and other metal materials and high temperature enameled wire, flexible connection, inductance coil welding. It is widely used in the welding of metal products in the fields of automobile and auto parts manufacturing, new energy power battery, photoelectric communication, electric light source, compressor, hardware, furniture, kitchenware, etc. The product has passed the patent certification of China Intellectual Property Office, China CCC certification and export CE certification.
