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 is flowing (start
program P
START
for the time t
start
)
2nd cycle
• Release torch trigger
• Slope on main program P
A
• 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 be-
tween the processes, starting with the standard process and followed by the pulse process. The
same applies if the situation is reversed.
3
rd
cycle
• Press the torch trigger
• Super pulse function is ended
• Slope in the end program P
END
for the time t
end
4th cycle
• Release torch trigger
• WF motor stops
• Arc is extinguished after the pre-selected wire burn-back time elapses
• Gas post-flow time elapses

For machine versions with pulsed arc welding procedures only.
This function can be activated using the PC300.NET software.
Refer to the software operating instructions.
