Design and functionMIG/MAG functional sequences / operating modes5.11.2 Non-latched operationFigure 5-14Step 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.099-005224-EW50108.11.201151
