1. Have the flexibility of making bigger size of gaskets (10" to 48") with or without inner ring. 2. Automatic welding saves great deal of working time, moreover, makes welding points strong and reliable, and welding span even. One key shift between automatic and manual welding. 3. One charge can load 20 to 25 kilogram wire. Can save a lot of working time, especially on making big size gaskets. 4. One charge can load 15 to 20 rolls of graphite. Having adjustable graphite holder. 5. Successfully use man-machine engineering principle, location most high frequent operation within arm-reach area, significantly reduce operators work load.
