WL10 Tungsten Electrodes Black For Welding

WL10 tungsten electrode -0.8%–1.2% lanthanum oxide (La₂O₃)

A non-radioactive,

Environmentally friendly tungsten electrode

Black color code.

Tungsten content : Min 97% 

Impurity：≤0.2(Fe,Si,Al,Cu

Welding operating Temperature: Stably up to 2300°C+.

◦ Direct Current (DCEN, Electrode Negative): Preferred. It provides greater penetration and less electrode erosion, making it suitable for stainless steel, carbon steel, and titanium alloys.
◦ Alternating Current (AC): Used for welding aluminum and magnesium. It must be paired with high-frequency arc starting, and the tip should be ground flat to prevent melting.
◦ Direct Current Reverse Polarity (DCEP, Electrode Positive) is strictly prohibited. It will instantly melt the tip, produce a large amount of tungsten inclusions, and render the electrode unusable.

Exceeding the upper limit of current is strictly prohibited, as it can quickly burn the tip, cause deformation and redness, result in scattered arcs, and lead to tungsten inclusions in the weld. If the current is too low, arc initiation becomes difficult and arc drift occurs.

1.According to the base material , and material thickness to be welded, determine the required tungsten electrode item type, and confirm that the tungsten electrode type used is correct according to different color marked .

2.Open the package and first check whether the product quality meets the quality standards and meet ISO 6848 .

First, inspect the tungsten electrode's metal surface color to ensure it is metallic silver-gray, shiny, uniform, and consistent. And then check for the material not have cracks, no peeling, no bubbles, no black oxidation; not have significant bending, no dents, and no chips. Additionally, check for splitting and burrs have or not etc. 

3.Check the tungsten rod cut face flat, dense, metallic bright white, no pores, no black spots . 

Please note , When tungsten electrode product has cracks, it can only be classified as scrap and cannot be used for welding work.

1. Fast arc starting: Ignites instantly with high frequency fast .

2. Concentrated arc column, no drifting, no trembling, no divergence , and stable .

3. After welding for a few minutes, the tip remains slightly rounded but not deformed or discolored.

4. Weld seam not have small black spots and no tungsten contamination.

5. After an arc interruption, it reignites immediately.

1. Will the purchase quantity affect the price? 

Yes, The price will have a little different between differnt quantity such as 1000-5000 Pieces , 5000-10000Pieces , more than 10000 Pieces . 

The more you buy, the cheaper the shipping and price will be.
