Stable arc welding WC20 cerium tungsten electrodes introudction
Premium tig welding electrodes WC20 2% Cerium Tungsten Electrodes , with grey tip color used for tig welding application. The product WC20 cerium tungsten electrode which also is a non-radioactive, environmentally friendly rare earth tungsten electrode, that with the industry standard grade WC20 , with a grey color tip marked called cerium tungsten electrodes . The matrix is high-purity tungsten doped with 1.8%-2.2% cerium oxide. It is an ideal replacement for traditional thorium tungsten electrodes and currently the most widely used and cost-effective tungsten electrode in industrial direct current welding.
Tungsten electrodes technological process ：

Applicable Welding Conditions
• Welding Polarity: Limited to Direct Current Electrode Negative (DCEN)
• Suitable Current Range: 5A – 250A , it usually for medium and small currents
•Welding Materials are carbon steel , stainless steel, alloy steel, copper, copper alloys etc.
Main application for pressure vessel welding, pipe welding, precision part welding, thin plate welding, instrument equipment welding, factory large-scale standard component production.
Usage Notes
1. Not recommended for AC welding (excluding aluminum and magnesium). Especially for welding aluminum, aluminum alloy materials, prefer to use WP pure tungsten.
2. Must use 99.99% high-purity argon gas; avoid working near air vents. 3.Before welding , we suggest to grinding the needle tip to a 15–30° cone shape for more concentrated arcs .
4. Avoid prolonged operation at excessive currents to prevent accelerated needle tip wear , to extend the service life of the product .

FAQ
1. Can i get electrode sample from your company ?
--There is no issue with providing samples.
2.Is there a charge for the sample?
--One sample is provided free of charge, but the buyer is responsible for shipping costs. For more than two items, the buyer must also cover both the sample cost and the shipping fee.
3.wc20 tungsten electrodes difference for others .
• WP Pure Tungsten electrodes , which is tip color is green, dedicated for welding aluminum and magnesium, AC only.
• WC20 Cerium Tungsten , tip color is grey , General-purpose DC, high cost-effectiveness, ideal for low-current precision welding.
• WL20 Lanthanum Tungsten is blue color, premium all-round performer, can use with both AC and DC, withstands high currents, longest service life.
