Mode of operation BASIC STEPPER
8.5.1
Sequence without tip dress
If the number of tip dress cycles will be programmed with „0",
then the Basic Stepper operates without tip dress function.
Each step will be passed once only.
Steps with number of spots = "0", will be jumped over.
With beginning of the last step with a number of spots greater "0", the electrode
has the state "prewarning".
At the end of the last step with a number of spots greater "0", the electrode
has the state "Max. electrode life".
If the control parameter "Stop at end of stepper" has the setting "off", then the
control will not stay, but continue to work with the parameters of the last %I
change.
If control parameter "Stop at end of stepper" has the setting "On", then welding
continues for 41 more welds.

8.5.2
Sequence with tip dress
If the count of the tip dress cycles will be programed greater „0", then the Basic
Stepper work with tip dress function.
The customer has the option to program the jump back to either 1
after tip dress.
Then the second step will be passed.
If the programmed number of tip dress has not yet reached, then at the first weld
of the third step the output "Tip dress request" will be set.
So long as the electrode will not be tip dressed, now will be passed on after
another the third step, the fourth step and the fifth step.
