Abstract
A high frequency thermode-driven device for use in hotbar soldering has a unitary metal support frame which is used for the secondaries of four individual transformers. The support frame also serves as the structural member to which the transformer and thermodes themselves are fastened. This is possible because the secondaries require only one turn; the upstanding ears of projections which extend radially outwardly from the support frame so as to protrude through the apertures in the transformer cores provide a source of voltage and become a secondary winding when connected to a load impedance, such as a thermode.
