>SEAM WELD MODE ON
With parameter SEAM WELD MODE set to ON, the work screen is as follows:
PROG. 001 SPOT 12340
WELD CYCLE 01.0 ~
CURRENT RMS 43.26 kA
CONDUCTION DEG 142°
This function allows the user to adapt the control unit to the requirements of a seam welder.
Consequently, welding current is supplied either continuously or via parameter COLD 2 in
pulse mode.
The welding current is measured during the WELD time only regardless of the program set-
up, that is to say either pulsed cycle or continuous cycle.
With the cycle-start command ON, the control unit keeps repeating the time set in the WELD
parameter. We suggest using short weld times to prevent the control unit from finishing a long
weld time, when the cycle start command is cleared.
In the seam operating mode, output EV3 is used as the roller-start command instead of being
used for the forging. On selecting the seam weld function, the control unit may work either in
WORKING MODE in FIX or in IK.
