In manufacturing the tungsten, smaller sized grains are better, because they produce more paths and therefore the oxides can more easily migrate to the tip. Surface finish is typically expressed as a Root Mean Square (RMS) or as a Roughness Average (Ra). Note that larger diameters can accommodate higher amperages; and larger diameter electrodes will last longer than smaller ones, but smaller ones will be easier to arc start. A good selection of tip/flat size will balance the need for several advantages. In addition to the materials listed above, there are other less common materials, such as 1% Thoriated, 4% Thoriated, 2% Yttriated, and also mixes of different oxides in the same tungsten. Tungsten welding electrodes should never be manually ground on an abrasive belt or wheel (particularly silicon carbide). Lanthanum Trioxide has the lowest work function of any if the materials thus it usually starts easiest and has the lowest temperature at the tip, which resists grain growth and promotes longer service life. Here is a comparison of 4 similar Tungsten Carbide Button Bits products for you to choose from, with so many different brands offering so many varying interpretations within the genre. For 3/32 or 1/8 diameter electrodes: using two pairs of pliers and a twisting motion or notching the electrode on the grinding wheel and then breaking the electrode by hand or with pliers. The EWLa-1 electrodes were developed around the same time as the Ceriated electrodes and for the same reason, that lanthanum is not radioactive. Oxide Distribution and Size:Oxide distribution is a key indicator of quality. In Figure 1 the 2% Lanthanated electrode still has a very small grain structure even after one hour of welding time at 180 amps on a 1/16 electrode.
