Our Factory Mid-frequency DC Transformer Advantages:
1,Medium frequency welding compare with low frequency welding
- Medium frequency welding transformer (MFDC welding transformer) loss power is very much smaller than low frequency welding transformer.
- The volume,weight of MFDC transformer is much smaller than 50Hz/60Hz welding transformer.
- MFDC transformer have a few welding splash,ensure welding workpieces perfect.
2,Our factory Mid-frequency DC transformer compare with other suppliers’ transformer
- Our MFDC transformer main parts apply weld structure,its advantage is small contact resistance,less fever.
- Our factory have over 20 years experience on power electronics cooling,our transformer average temperature lower than 5 degree compare with other supplier
- Our MFDC transformer processing equipment adopt advanced CNC machine,ensure transformer parts deviation reduce least.
