>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.
SEAM WELD MODE PARAMETERS TABLE
