No need to grind, just insert these stingers and start welding! When it comes to TIG welding, tungsten electrodes are the most important part of the application. PS Also it helps to have a few Tungsten electrodes ready, so when you mess one up you can just swap over and keep welding. With DCEN (Electrode Negative) welding, you need to sharpen the tungsten electrodes to a specific angle. When using the grinding wheel to sharpen your tungsten make sure you do not turn the tungsten while sharpening it. However, if the electrode is completely contaminated, then you need to cut off the contaminated portion. Why do we have an unstable arc? Tungsten also has high resistance and very high corrosion resistance and its melting point of 3,422 C is ideally high for welding using alternating current. Unless someone can show me why Chem Sharp is a bad sharpening solution, I will continue to use it as my backup of choice.Al SwillingChattanooga, TN, USA. Figure 2. It looks like 3-mm round plane surface rod. Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. For 1 disk, I vote 80 grit. although i use 1/8 tungsten, it looks like what u using is smaller. After all, it is the tungsten electrode that transmits the arc from the welder to the The grinding wheel is recommended to be made of diamond and should be reserved for grinding tungsten electrodes to avoid contaminating the electrode tip with foreign metal or dirt.
