The tungsten should never touch the workpiece.  

TIG stands for tungsten inert gas and is technically called gas tungsten arc welding (GTAW). The process uses a tungsten electrode located in a hand held torch that delivers the current to the welding arc. The tungsten and weld puddle are shielded and cooled with argon. A filler rod is used to add material to the weld puddle. During the welding process the tungsten should never touch the work piece. When this happens you will need to remove the tungsten and regrind the tip. Some of the advantages of this type of welding include strong high quality welds and many material options. One disadvantages of TIG welding is the speed is much slower compared to some of the other welding methods.
