5.1.11.2 Automatic cut-out
The welding machine ends the ignition process or the welding process with an
• Ignition fault (no welding current flows within 5 s after the start signal).
• Arc interruption (arc is intrerupted for longer than 2 s).

Step 1
• 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.
• Changeover to the pre-selected wire speed after the set ignition time (tZn).
Step 2
• Release torch trigger.
• WF motor stops.
• Arc is extinguished after the pre-selected wire burn-back time elapses.
• Gas post-flow time elapses.
