Medium Frequency DC Welding Machine , 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 (
projection ) 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.

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. To make the power supply unit load balance: MF inverter
projection welder adopts the three-phase sources which can store
energy.
4. 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.
5. More precise and fast control of current: Compare with low
frequency system, it is able to analyze more parameters in a more
precise way.
6. More reliable process: For most of the applied resistance
welding metals, to use DC to weld will help to achieve better
effect.
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
