Let’s start with the best: The E3® is a tungsten electrode developed by ABICOR BINZEL with a mixture of rare earth oxides as doping elements, which is suitable for both direct current and alternating current welding and practically every metal. It has excellent ignition properties and is therefore also often used for automated processes.
A tungsten electrode is a so-called non-consumable electrode, but in the course of its use it also changes its properties, which come from the doping elements added – and the shape. To be precise: at the top, where things get hot. Doping elements and their task – a little excursion
You will also find chemical solutions to sharpening your tungsten electrode. Chemical wolfram sharpeners work with all types of wolfram electrodes. All you have to do is to heat the electrode up and dip it in the powdered chemical. To heat the electrode up, you can use a propane torch or just grind it against a piece of metal.
Jul 18, 2002· Also, grind a taper on the tungsten electrode that spans the distance of no more than two and a half times the electrode diameter. As an example, a 1/8-in. tungsten electrode would have a taper 1/4 to 5/16-in. long. Remember to use a grinding wheel especially designated for the purpose of grinding tungsten electrodes.
Lanthanated electrodes work well on AC or DC electrode negative with a pointed end or they can be balled for use with AC sine wave power sources. These electrodes maintain a sharpened point well and can replace both ceriated and thoriated because, unlike thoriated tungsten, these electrodes are suitable for AC welding and, like ceriated

Zirconiated Tungsten offers reliable arc-striking and a low burn-off rate. Zirconiated tungsten welding electrodes are ideal for AC welding because they maintain a balled tip and have a high resistance to contamination. Zirconiated tungsten has a current-carrying capability that is equal to or greater than that of Thoriated tungsten.
Dec 11, 2020· Zirconated Tungsten Electrodes (White) And third on our list of the main types of TIG welding tungsten options is Zirconated tungsten. This is another electrode that has always been used as a multi-purpose choice for AC power. When AC options are limited, zirconated tungsten delivers.
As the green pure tungsten electrode prevents the formation of a pure square wave due to its inertia and high work function, it is not recommended to use this welding electrode with inverter power sources. The ideal replacement for the green tungsten electrode is the E3®.
Mar 05, 2021· A pure tungsten electrode or a zirconiated tungsten electrode works best with AC aluminum welds. If you’re using a tungsten electrode, make sure it’s large enough in diameter to carry the welding current efficiently. An AC power supply …
Tungsten is the main metal used in Gas Metal Arc Welding (GTAW) or TIG electrodes. This has to be selected with care. Tungsten is hard and has high temperature resistance and the highest melting point of 3,410degrees C. The tungsten electrodes are available in various sizes and lengths.

Tri-Mix tungsten electrode (AWS classification EWG) combines three non-radioactive rare earth materials (La2O3, Y2O3, CeO2) into one tungsten. Extensive testing has resulted in the development of an optimum composition blend for a high performing tungsten electrode. Performance features include: Easy arc starting and re-ignition, high arc
for the preparation of tungsten electrodes – electrode geometry, electrode preparation equipment and electrode preparation techniques – will help ensure that a welder is more like Tom Brady and less like Ryan Mallett. Electrode geometry Geometry choices affect key tungsten attributes, such as electrode life, ease Tungsten electrode geometry.
The inverter power supplies provide adequate arc cleaning with as little as 15% electrode positive. Reducing the amount of electrode positive makes the process more efficient, increases weld penetration, and reduces the amount of heat going into the tungsten electrode, which means smaller diameter, pointed electrodes can be used. This further
A clean, precision diamond ground tungsten electrode delivers snappy arc starts, and better puddle control. Dedicated tungsten grinders are the simplest, most cost-effective way to improve your TIG & Plasma Arc Welding.
Tungsten Carbide Electrodes Electrical discharge machining (EDM) is a popular machining method, valued for its ability to drill into extremely robust alloys used in industries such as aerospace, defense, energy, and biomedical engineering. EDM operates through repeated sparking, each spark burning away a small amount of material.
Lanthanated tungsten electrode contains a minimum of 97.8% tungsten and 1.3% – 1.7% lanthanum. Hence these electrodes are known as 1.5% lanthanated tungsten electrodes. These electrodes tend to have a low burn-off rate and a good amount of arc stability …
Tungsten and Thoriated tungsten electrode sizes and current ranges are listed in Table 1.2, along with shield-gas cup diameters recommended for use with different types of welding power. This table provides
Tungsten is a very brittle metal: rigid and with a very high melting point. In these respects it is unlike many other metals that are more common. These properties give tungsten electrodes greater penetrative power than brass or copper. The rigidity and high melting point of tungsten counter the softness and relatively low melting point of silver.
Mar 05, 2021· Truncated and pointed tips can be used for thoriated, lanthanated, ceriated and pure tungsten for welding processes powered by inverters AC and DC.

To properly ball the end of the tungsten, apply the AC amperage recommended for the electrode diameter and the ball on the end of the tungsten will form itself.
Electrode The electrode used in GTAW is made of tungsten or a tungsten alloy, because tungsten has the highest melting temperature among pure metals, at 3,422 °C (6,192 °F). As a result, the electrode is not consumed during welding, though some erosion (called burn-off) can occur.
TIG Tungsten Electrodes Tungsten Inert Gas (TIG) welding is a popular type of welding that utilizes tungsten electrodes to join various metals.
