The welding process called ELMA-QS designates the ELMA spot welding
procedure that allows for the energy applied and observes the welding time
by means of the QS (quality assurance) supervision system. This process be-
ing selected, the following screen appears:
If both LEDs “Tool” and “Electrode” are flashing on the lower control panel,
the current tong needs to be calibrated. This calibration is necessary for pre-
cisely determining the process impedance during the welding process and for
checking the tool (tong) used.
After you have selected CHECK-EL from the menu “Tasks and gun set-up“,
press the start button to initiate calibration. DO NOT FORGET that the
calibration must be made with clean copper-bright electrodes WITH-
OUT work piece (electrodes).
The calibration result is indicated by the LEDs of the “QS lights“ as well as
by the LEDs “Tool“ and “Electrode“ on the lower control panel:
