Latched with changing welding method (process switching)
To activate or set the function - See 5.8.17 Expert menu (MIG/MAG) chapter.
1st cycle:
•
Press and hold torch trigger
•
Shielding gas is expelled (gas pre-flows)
•
Wire feed motor runs at "creep speed"
•
Arc ignites after the wire electrode makes contact with the workpiece; welding current flows
•
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.
2nd cycle:
•
Release torch trigger (no effect)
rd
3 cycle:
•
Press torch trigger (no effect)
th
4 cycle:
•
Release torch trigger
•
Super pulse function is ended
•
WF motor stops
•
Arc is extinguished after the pre-selected wire burn-back time elapses
•
Gas post-flow time elapses
This function can be activated using the PC300.NET software.
