Description
nungsquelle — der Basis des Transistors 11 über den Widerstand 13 ein durch die Zenerdiodel2 stabilisierter Gleichstrom zugeführt, der den Transistor 11 unter Überbrückung des Einstellwiderstandes 7 leitend macht. Der Widerstand 7 ist somit außer Funktion, so daß der Schweißgenerator auf einen am Stellwiderstand 18 einstellbaren Zündspannungswert erregt wird. Wird nunmehr nach erfolgter Zündung ein Schweißstrom entnommen, so tritt durch den im Stromwandler 15 induzierten und im Gleichrichter 16 gleichgerichteten Strom eine Kompensation des Basisstromes und damit Sperrung des Transistors 11 ein, wodurch der Einstellwiderstand 7 wirksam wird. Die Erregung wird damit auf den jeweils an diesem Widerstand eingestellten Wert eingeregelt, so daß der Generator auf der durch den Einstellwiderstand 7 gewählten statischen Kennlinie arbeitet. Tritt nunmehr eine Unterbrechung des Stromflusses ein, so wird der Einstellwiderstand 7 wieder überbrückt und die Erregung der Erregermaschine auf den am ίο Widerstand 18 eingestellten Zündspannungswert eingeregelt. voltage source - the base of the transistor 11 through the resistor 13 stabilized by the Zener diode 2 Direct current is supplied, which conducts the transistor 11 by bridging the setting resistor 7 power. The resistor 7 is thus inoperative, so that the welding generator is on an on Variable resistor 18 adjustable ignition voltage value is excited. Is now after ignition If a welding current is removed, then occurs through the induced in the current transformer 15 and in the rectifier 16 rectified current a compensation of the base current and thus blocking of the transistor 11 on, whereby the setting resistor 7 becomes effective. The excitement is thus on each at this Resistance adjusted value, so that the generator on the by the setting resistor 7 selected static characteristic works. If there is now an interruption in the flow of current, so the setting resistor 7 is bridged again and the excitation of the exciter on the am ίο Resistor 18 adjusted ignition voltage value.
