Abstract
952,441. Arc welding systems. J. MORELISSE ELECTROTECHNISCHE FABRIEK NEDERLANDSE KOOLBORSTEL FABRIEK N.V. Jan. 25, 1963 [Jan. 26, 1962], No. 3167/63. Heading H2H. To reduce the no load voltage across the electrodes of an arc welding system, the welding transformer is disconnected from the supply and reconnected to the secondary winding of an auxiliary transformer. When the welding circuit is completed, a cement transformer 27 energizes through a transistor amplifier 23 relays 7, 19 which switch the welding transformer directly to the supply. The currentvoltage characteristic of the auxiliary transformer should have a relatively flat curve. The transistor amplifier may be alternatively controlled by electrode voltage.
