How do I use the Lift-Arc TIG mode to start the arc without contaminating the tungsten electrode?

In Lift-Arc TIG mode, only a low sensing voltage is present at the output terminals before the electrode touches the workpiece, preventing overheating or contamination. For best results, firmly touch the tungsten electrode to the workpiece at the start of the joint, hold it in contact for 1 to 2 seconds, then slowly lift the torch to open the arc. To end the weld, quickly lift the torch. (Page 23)
