Tungsten Electrodes are used for TIG welding, Tungsten Electrodes diameters are from 0.25 to 6.4mm, the standard length are from 75-600, while the most commonly used model are the diameter of 1.0,1.6,2.4 and 3.2.  The shape of Tungsten Electrodes is an important factor.

There are three series for your select as follow.

 Pure Tungsten electrode: Pure Tungsten electrode is suitable for welding magnesium ,aluminum and their alloy and stainless steel under alternating current.

 W?CCe electrode: This is a new type non-selfconsuming, radioactivity-free welding electrode used in TIG??welding and plasma welding.

 W-La electrode: It has a good property and conductivity reaches WT20 electrode,it can be used alternating current and works well.
