HF-2700A, HF-2500A - Alimentation électrique de soudage par point à onduleur haute fréquence (anciennement connu sous le nom de HF27, HF25)
Les commandes de la série HF-2500A de soudeurs en boucle fermée permettent de relever les défis du micro-assemblage. Les soudures miniatures sont extrêmement sensibles aux fluctuations thermiques mineures du procédé de soudage par résistance. L’excès de chaleur déforme et détruit les pièces, alors que le manque de chaleur entraîne un assemblage faible et inacceptable. Pour réaliser des soudures cohérentes des petites pièces aux micropièces miniatures, la chaleur doit être régulée avec précision. Cela nécessite une régulation d’énergie supérieure.
