MIG/MAG welding
Latched mode with alternating welding process

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)

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.
Refer to the software operating instructions.
