Customizable according to requirements
Energy saving, power saving, high efficiency, low operating cost,
and high welding quality.
Product overview: The medium frequency inverter DC spot welding
machine converts the power frequency (50Hz) AC to the medium
frequency (1000Hz) DC output. The time resolution is higher than
that of the power frequency, the control accuracy is also improved,
and the output current is not affected by the change of the
secondary output circuit. It has high thermal efficiency, large
output power rate and better welding quality. Compared with the
traditional power frequency welding machine, inverter medium
frequency DC welding will be efficient and energy-saving. It 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

Features
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.
