The EN1000 is a microprocessor based resistance welding control. It can store as many as
11 parameters in each of 50 unique schedules. These are held in non-volatile memory for
storage. It can perform Up Slope, Down Slope, Quench, Temper, Pulsation, Seam, and Spot,
all of which can be combined to provide for any possible welding schedule imaginable. In
addition, schedules can be chained together to provide more complex welding sequences.
Despite the seemingly complicated possible welding schedules, the EN1000 is simple to
program and operate. Versatility is built in to allow the individual to configure the control
to any application.
This control provides an accurate, predetermined welding schedule for a specific number of
cycles upon an external command. The initiation command is usually provided by the
closure of a normally open switch, located on or installed as part of the welding machine,
which starts the welding interval. The initiation switch need not remain closed for the
duration of the weld, but must be opened after the welding interval is completed in order to
re-initiate the control. After a weld has been started, the control cannot be re-initiated until
the previous weld is completed. All control functions are performed digitally.

"Timing" is achieved by counting each cycle of the line current directly. This method of
"timing" allows this control to be used on either 50 or 60Hz power without special
adjustments.

35(6685(6:,7&+),5,1* is a terminal strip connection which allows the control to
be initiated from a pressure switch closure. Remove the jumper from TS1-PS1 and
