sheets, the limit conditions are either with 1 or 3 sheets. The constant welding current is
adjusted by the TE700 control unit (if the value of the r parameter for using the welding unit is
less than 100.0%). The operator must then check the values of the r indicator when welding
with 1 sheet and set this value as minimum limit and if welding with 3 sheets, set this value as
maximum limit.
If a more accurate spot quality control is required, activate the QUALITY-T parameters to
check the initial thickness of the sheets and the electrode penetration at the end of the
welding cycle, and the QUALITY-R parameter to obtain a measurement of the initial and final
values of the resistance.
The presence of the QUALITY-T and QUALITY-R parameters depends on the control unit's
configuration and which spot welder is used.
However, it is not possible to undoubtedly assure that the piece has been effectively
welded, as all the conditions and parameters involved in the welding process
execution should be checked.
