In SEAM welding, the duty cycle is typically higher since the weld current is
flowing for more time. Use caution not to overheat the transformer or control
circuitry when in SEAM mode. See Application Note 700199 regarding External
Surge Resistors.
The EN1000 or EN1001 Control is equipped with a Temperature Limit Switch, usually mounted
on the Heatsink of the SCR Contactor. An ERROR CODE of
0101
0101
01 will appear on the display if the
Temperature Limit Switch is open.

02 – Adjust CURRENT During Weld
In this mode, during welding it is possible to change PERCENT CURRENT (Up-Down current
adjustment) with DATA push buttons. Use DATA 10s push button to increase PERCENT
CURRENT, and DATA 1s push button to decrease.

03 – SEAM/SPOT Sequence Combination
This mode is SEAM/SPOT sequence combination. Initiation FS7 and schedule 10 will always
be SPOT sequence in this mode. SEAM sequence can be initiate with FS3 either in
CONTINUOUS or INTERMITTENT mode, and, whenever FS7 is closed, control will jump
from SEAM to SPOT sequence on schedule 10.
Also in this mode, since PROM firmware version 619016-002P, it is possible to add a CHAINED
SPOT sequence with no welding schedules before CONTINUOUS or INTERMITTENT SEAM
part of the sequence with FS3 initiation.

4 – DELAY Compensation
In CONSTANT CURRENT mode on EN1001 Controls, this mode is used to add DELAY before
control starts to compensate or regulate current. The variable x indicates the number of initial
cycles during which compensation is delayed. For example, if

weld cycles, control will only perform current measurement without any compensation, and on
sixth cycle it will start to compensate.
