Definitions

  • the object of our invention is to overcome the above difculties, and to provide a Welder which may be used for either spot or spot-seam Welding and in which the time of the duration of the current impulses and the currentless intervals can be varied independently of each other.
  • switch 21 is placed in position B, whereby a regular series of current impulses is produced, and the duration of the lcurrentless time inter- 20 valsicanbeadjusted independently of the duration of these irnpulsesffI vSuch independent control is very advantageous particularlywhen welding objects of different shape from the same material.
  • chain for determining theduration of currentless time intervals operates v-in a similar manner to the other retarding chain.
  • denser comprising a resistance, a second condenser connected across said rstkcondenser with the interposition of said resistance, and means to charge said second condenser to always the same polarity with direc'tl current when curreni'I oWs in the load circuit.
