1st cycle:
• Press and hold torch trigger 1.
• The gas pre-flow time elapses.
• The arc ignites.
• The welding current flows and immediately assumes the value of the starting current Is.
• The welding current increases over the set Up-slope time to the main current I1.
2nd cycle:
• Release torch trigger 1.
• The main current I1 falls over the set Down-slope time to the end-crater current IE (minimum current).
• Arc is extinguished.
• The set gas post-flow time elapses.
