4.2 Electrode tip

DC welding
For DC TIG welding, grind the tip of the tungsten electrode lengthways, into cone shape. The sharpened electrode
tip provides a steady and concentrated arc into the weld piece. The sharpening angle and length has an effect on
the arc width and penetration depth.
Sharpening principle:
Where I = 1...5 x d.
The sharpening length best suited for your purposes depends on the most used welding current level:
a. Low currents
b. Mid currents
c. High currents
When sharpening the electrode, always grind along the electrode.
