NOTE: When the EN1000 series controls are used for SEAM WELDING, RESISTANCE
BRAZING, or other high duty cycle applications, additional surge resistors must be
installed in accordance with instructions on the wiring diagram. These resistors may be
obtained through your resistance welder dealer or directly from ENTRON CONTROLS
INC.
If a control in which the resistors have been added is later used in a spot welding application,
it is not necessary to remove them.
