8.4.1 SETTING UP CURRENT REGULATOR (for Primary Sensor or
Secondary Rogowski Coil with Auto-Range selection only)
1. Setup must be done in SPOT mode (

00). If doing seam welding, re-program SEAM
mode parameter after the setup is complete. The control must be initiated using a FS3
initiation switch connected between TS1-FS3 and TS1-GND. If the machine does not have
permanent initiations using this terminal, temporarily connect a switch to FS3.
2. Make sample welds with CONSTANT CURRENT disabled (

00) to determine proper
welding transformer tap switch setting. PERCENT CURRENT should be between 70–80%*
and WELD time should be the recommended number of cycles for material being welded.
* In order for the control to adapt to changing conditions, it must be able to adjust current. If weld is made
around 75%, the control can move up to 99% or down to 20% if necessary to maintain current constant
when the control is in CONSTANT CURRENT mode.
3. Put the control in PROGRAM mode.

This presets schedule 49 with specific setup parameters, including 30 cycles of SQUEEZE
time, 99 cycles of SQUEEZE DELAY time, and Valve 1 output. The control will automatically

If necessary, SQUEEZE time or VALVE output may be changed to match machine
requirements. Switch to PROGRAM mode, change SQUEEZE time or VALVE and press
ENTER. Return to OPERATE mode.
7. Using the same material already welded**, insert it between the machine electrodes, initiate
a weld sequence and hold the initiation switch FS3 closed. The machine electrodes will
close and the control will sequence through a preset test schedule. When setup is complete,
the control counts down on the display and returns to schedule 00.
** While in setup, the control makes multiple welds using 4 cycle pulses. If the part being welded cannot
support weld times of 4 cycles without expulsion or distortion, the parameters measured may not provide
correct setup data. In this case, run the setup with no material between the electrodes.
8. Release the initiation switch. The control is now set up and ready to operate. Sequence
parameter CURRENT must be re-programmed now as a four-digit number (example: 80%
