Abstract: A monitoring and control system for a resistance welding apparatus. The system monitors the quality of a weld as a weld is formed and terminates the welding current when a quality weld is completed. The monitoring function is performed by detecting a change in the instant welding current is extinguished at the end of half cycles of welding current in the secondary winding circuit of the welding transformer. The weld current is terminated when a detected charge in the instant current is extinguished relative to a reference equals a preprogrammed value which is indicative of an acceptable quality weld between welded parts.

Abstract: A snap-together segmented fanning strip that simplifies grouping of wires or spreads out the wires in a cable of a machine tool or the like for distribution to channel-mounted terminal blocks of a terminal strip to complete a series of electrical circuits. The segmented fanning strip includes a plurality of fanning blocks which incorporate a snap fit between the blocks rather than a tongue-in-groove or a keyed connection to arrange the fanning blocks in a row in a side-by-side abutting relation. To assemble the blocks in a segmented fanning strip, the top front edge of one block interfits into the channel at the top outer edge of the other block so that they are side by side and then the blocks are pressed together to snap the bottom edge of the one block into the upwardly facing channel in the bottom edge of the other block to establish the connection between the blocks.
