Ceriated tungsten electrode sharpener is one kind of non-radioactive products on welding working.
The features of the product are at low current conditions have good starting arc performance, a smaller-dimensional arc current.
Therefore, it commonly used in the pipe, stainless steel products and welding of small precision parts. At low current DC or
electrode diameter under the conditions at 2.0mm below cerium thorium tungsten electrode tungsten electrodes are the preferred alternatives.
