A strip (21) of pairs of terminals (13 and 14) are incrementally advanced into a bonding station (24) where electrical components, e.g., metallized film capacitors (10), are successively advanced adjacent to each pair of terminals. Each pair of terminals is bent into engagement with a pair of heat fusible end electrodes (11 and 12) on each electrical component. Sets of three welding pulses are respectively applied by a pair of welding devices (36 and 37) to each terminal. The welding pulses are monitored and if found to be below a predetermined magnitude, additional sets of welding pulses are applied to the electrodes. If a programmed control system ascertains that three successive welding attempts are unsatisfactory, or if five welding attempts are unsatisfactory in nine cycles of operation of the overall apparatus, further cyclic operation of the apparatus is interrupted. Facilities (38, 39 and 40) are provided to upset and reshape any metallic flash resulting from the welding operations. |
