Product Description
Permanent magnet medium frequency generating- welding machines are our NEW products which we work with the professor and Dr from the institute
of engineering and technology,Southwest University.It is designed for the first time in China and got many national patents. The project is supported by the National Innovation Fund from the national Ministry of science and technology.
The traditional engine driven welders are with power frequency and exciting alternator. Disadvantages are obvious in the following:
1. Large size heavy weight which is not easy to move.
2. Fuel consumption is high.
3. The control system is electronic. It is too complicated and the failure rate is very high.
4. It is Exciting alternator. The efficiency is as low as only 60%. Iron loss and copper loss is large.
5. The frequency output is 50 to 60hz.The welding is not smooth and is difficult to weld the pipelines.
Medium frequency is new technology which has been widely used in the welding of car industry.Advantages of welders with permanent magnet -medium frequency are following:
1. Compact size and light weight makes it easy to move and maintain. The efficiency can reach as high as 90%.Fuel consumption is lower.
2. Reliable control system: simple mechanical system is applied, which make it difficult to break down. Failure rate is very low.
3. Frequency output is 500hz.This is make the welding quality very stable and smooth with little splash, deep bath and beautiful welding seam.
4. The reaction is very quick (1-3ms), which is only 1/20 of the power frequency welders.
5. Welding current can be reduced by 40%. Life for Electrode is much longer. (To welder 4.0mm electrode, the power frequency welders need more
than 180A. But the medium frequency welders need only 120A to 130A.That is why the traditional welders cannot use argon arc but our welders
can do)
The popular models are 130A, 210A, 250A, 300A.We have sold them to Southeast Asia and Russia and the feedback from market is very good.
