First cycle (current)
• Press torch trigger 1 (BRT 1), the gas pre-flow time elapses.
• HF ignition pulses jump from the tungsten electrode to the workpiece. The arc ignites.
• Welding current flows.
Second cycle (current)
• BRT 1 Release .
• The welding current ramps up to the main current AMP in the selected up-slope time.
First cycle (wire)
• Press torch trigger 2 (BRT 2).
Wire electrode is fed.
Second cycle (wire)
• BRT 2 Release .
Wire electrode feeding is stopped, wire electrode is returned by the set wire return value.
Third cycle (current)
• BRT 1 Press .
• The main current is reduced in the selected down-slope time.
Fourth cycle (current)
• BRT 1 Release , the arc extinguishes.
• Shielding gas continues to flow in the selected gas post-flow time.
