Abstract

Bu buluş bir nokta kaynak makinası (1) ile ilgilidir. Bu kaynak makinasında (1), kaynak akımı uygulanmadan önce, çok kısa süreli ve çok küçük boyutlu, sabit bir test akımı uygulanmaktadır. Bu akıma karşılık ölçüm devresi (7) tarafından ölçülen yük devresi direnç değeri, kontrol devresinde (6) kayıtlı bulunan, önceden ölçülmüş yük devresi direnci ve bunlara karşılık gelen kaynak akımı değerleriyle kıyaslanarak, söz konusu yük devresi için uygulanması gereken kaynak akımının büyüklüğü belirlenmektedir.The present invention relates to a spot welding machine (1). In this welding machine (1), before the welding current is applied, a very short test time is applied. The magnitude of the welding current to be applied to the load circuit is determined by comparing the load circuit resistance value measured by the measuring circuit (7) to this current, the measured resistance of the load circuit stored in the control circuit (6) and the corresponding welding current values.
