Welding on Flat Surface
Theoretically the arc is formed between the tungsten tip and the workpiece, while the nearby filler
is melt and drawn to cover the spot.
So it is important that the tungsten tip is in a precise position, and it should always be closer to the
surface and farther from the filler. Pls see the following pictures.
