5.2.5.13 Latched special with alternating welding process

Pulse arc welding machines only.
I
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

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.

3 cycle
• Press the torch trigger
• Super pulse function is ended
• Slope in the end program P
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
This function can be activated using the PC300.Net software.
Refer to the software operating instructions.
5.2.6

MIG/MAG automatic cut-out

If pressing the torch trigger does not ignite the arc or if the arc is interrupted by the torch being
removed during the welding process, automatic cut-out occurs within 5 seconds. The welding
machine ends the welding process immediately (open circuit voltage or welding current, wire
feed and shielding gas are shut off).
