The design of the tip varies as the welding task changes. Pls see the following pictures. *NOTE: 1. Dull pin is the most stable shape of tungsten pin. We suggest the use of this shape as much as possible.
- Page 6 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.
- Page 7 Welding multiple seams The pin-filler distance should be about the filler diameter. The filler should be put tightly against the privous seam. Set Filler Function: To get an even and flat welded surface, we can pre-weld the fillers, as shown in the left picture.
- Page 8 The rest of a Corner Set Filler Function: To get an more stable welding result, we suggest that you use the Set Filler Function to pre-weld the filler precisely on top of the edge of the corner. Hence you can free your hand from stabilizing the filler and especially helps if the space is narrow.
