The arc ignites through contact with the workpiece:
a) Carefully place the torch gas nozzle and tungsten electrode tip against the workpiece (lift arc current
flows independent of the set main current)
b) Angle the torch above the torch gas nozzle until the distance between electrode tip and workpiece is
approx. 2–3 mm (arc ignites, current increases to the set main current).
c) Lift the torch off and bring into normal position.
Complete the welding task: Remove the torch from the workpiece so that the arc extinguishes.
