Abstract

Perfeccionamientos en transformadores toroidales de soldeo por resistencia, del tipo adaptables para utilizar en máquinas soldadores portátiles, caracterizados porque se dispone un núcleo cilíndrico regular y hueco de hierro enrollado a partir de una tira continua de material magnético de núcleo de hierro, un material eléctricamente aislante que rodea el citado núcleo de hierro un arrollamiento primario en una sola capa formado por una serie de segmentos eléctricamente conductores de manera que formen u arrollamiento de capa única y continua, de forma toroidal , que rodea el citado núcleo de hierro y el aislamiento un secundario de una sola espira muy cerca de dicho arrollamiento primario y núcleo de hierro, pero aislado de los mismos y rodeándolos totalmente, de manera que formen una estructura cilíndrica compacta de transformador eléctrico con bornas fijas del secundario en un extremo y bornas del primario en el extremo opuesto.
