For quality assurance, you should adjust your welding equipment to your real conditions
by means of Scaling.
The following parameters will be adjusted through Scaling:
- toroid sensitivity
- conversion factor for pressure output
- zero shift for pressure output
Scaling by manual entry:
Select Scaling on the first screen, e.g.
D
For automatic scaling/calibration, see pages 7-24 and 7-31.
D
Check the quality of your spot welds.
D
The actual current values of the spots welded are displayed in various windows, e.g. in
the Programming - Sequence - Actual Values window.
If necessary, adjust the following programmed values to your requirements:
D
- [%I] and [Weld Time]
- Type and number of [Weld Times]
- Current upslope and downslope times [Slope]
The [%I] Stepper refers to the [Amount of current] and the [Pressure]. The stepper values
are experimental values, it may not be possible to enter these values before having
closely monitored the electrode lives.
Procedure for setting the Stepper functions:
Program the Stepper and Tipdress Curves in the Basic-Setup.
D
Activate Stepper in the Programming - Stepper window.
D
Enter the electrode parameters for calculating the wear.
D
Select a Stepper Curve and a Tipdress Curve.
D
Enter the number of dressings.
D
Program the Stepper for the new electrode, stepper and tipdressing areas.
D
Program the Pressure Stepper values.
