2nd cycle
•
Release torch trigger
•
Slope on main program P
•
Start the process alternation starting with process P
The welding processes alternate between the process P
P at the specified times (t
B
If a standard process is stored in the JOB, this means that there is a permanent alternation
between the processes, starting with the standard process and followed by the pulse process.
The same applies if the situation is reversed.
