There are some peculiar conditions:
If the OFF TIME (16) is set to zero, the control unit works in single cycle.
By setting the PRE-WELD parameter (3) to zero, the pre-weld is not carried out.
By setting the POST-WELD parameter (13) to zero, the post-weld is not carried out.
We recommend activating the CONTROL MODE in CUR and checking the use limit conditions before starting
the production: if use is with 2 sheets for example, limit conditions are with 1 or 3 sheets. The weld current is
adjusted by control unit TE470/TE480.
However, it is necessary to check the welding current value with one sheet so to be set as minimum limit and to
check it with 3 sheets so to be set as maximum limit.
However, it is not possible to undoubtlessly assure that the piece has been effectively welded, as all the
conditions and parameters involved in the welding process execution should be checked.
