Artificial Japan Eectrical Network

Because of unique opportunity, I managed to obtain two old ultrasonic  generators from the scrap equipment of one local factory. Nobody knows what to do with them in comparison to many another useful devices they gave away, so the way to them was open. Now, the question is - could we use the generators for the flexible PVC material welding?

Connected transformers to produce a 96 V power.

At first, we need an electrical power. The generators was made by Honda Electronics and have power input for Japan network (maybe regulated), 100 V, 150 W. I don't have any regulation transformer and making stable transformer from 230 V to 100 V is expensive. So, I take four similar transformers to 24 V taken from four old VCRs I found in trash before many years. At the primary, I connected them in parallel to a 230 V. The secondary winding was then connected in series to get 96 V. When loaded to 150 W, there was no significant voltage drop. At last, the Japan outlet connector was added. I had it at my storage I don't know from.
