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
A
:
The welding processes alternate between the process P
A
stored in the JOB and the opposite process
P
B
at the specified times (t
2
and t
3
)
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)
3
rd
cycle:
• Press torch trigger (no effect)
4
th
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
NOTE
This function can be activated using the PC300.Net software.
Refer to the software operating instructions.
