HF-2700A, HF-2500A - Fuente de poder para soldadura por puntos con inversor de alta frecuencia (anteriormente conocido como HF27 y HF25)

Los controles que se encuentran en la HF-2700A y HF-2500A de soldadores de bucle cerrado abordan los retos de las microuniones. Las soldaduras en miniatura son muy sensibles a las pequeñas fluctuaciones del perfil térmico en el proceso de soldadura por resistencia. Un exceso de calor deforma y destruye las piezas, mientras que la falta de calor produce una unión débil e inaceptable. Para lograr unas soldaduras constantes y fiables de piezas pequeñas y microminiaturas, el calentamiento se tiene que controlar de forma exacta, lo que requiere un control superior de la energía producida.
