OUT-OF-PHASE ELECTRICAL WELDER AND PROCESS |
摘要 |
Electrical welding process and device using intersecting, electrically contacting welding elements are disclosed. The intersecting welding elements are powered out of phase from each other, such that there is no short circuiting around the welding elements being heated and no electrical insulation is needed between intersecting welding elements. Current directors can be used to alternatingly direct the current through the intersecting welding elements. The process and device can be used to weld various workpieces, including thermoplastic binders and folders. |
