- If possible, use the dedicated grinding machines. Using the grinder for other applications can damage the grinding disc.
- Grind the tungsten to an angle of about 60 degrees for longer life.

Can you grind tungsten on a bench grinder?
Remember, only grind tungsten on a bench grinder that is dedicated to tungsten. If you grind your electrode on a wheel that is shared by steel, you run the risk of embedding contaminants in the tungsten.
How do you sharpen tungsten at home?

Can tungsten get contaminated from grinding it?
A lot of welders are using stone grinders to sharpen their tungsten and it can lead to poor grinds and contamination right off of the wheel.
What is the best way to sharpen tungsten?

Which end of tungsten do you grind?
We recommend you flatten or blunt the tip of the tungsten electrode after sharpening. The guideline for this is approx. ten percent of the electrode diameter – an electrode with a diameter of 1.6 mm then has a blunt tip of approx. 0.15 mm.
Can you sharpen tungsten with a grinder?
A bench or angle grinder is the most common tool used to sharpen tungsten electrodes. The grinder used to sharpen tungsten should be clean, have a fine hard stone, and use it for grinding tungsten only.
What will grind tungsten carbide?
Super-abrasives, namely CBN and diamond, are used to grind very hard material. Hard ferrous materials are ground with the CBN, while non-ferrous materials (like the WC) are best ground with diamond.
What grinding wheel do you use to grind tungsten carbide?
Resin bond diamond grinding wheels are still widely used for grinding tungsten carbide because of the low cost and simple manufacturing process. When grinding large-sized grinding wheels, only choose resin bond grinding wheels.
Why is my tungsten turning black?
If the tungsten electrode turns from its normal color of light gray to a shade of purple or black, that is an indication to increase post-flow time even more. In addition to causing various weld puddle troubles, contaminated tungsten electrode is also the leading cause of an unstable arc.
Why is my tungsten cracking?
The electrical conductivity of these tungsten electrodes is extremely high compared to other types. If the starting current is set too high, the tip of the tungsten electrode will split immediately at the start.
Why does my tungsten ball up?
Either too much current for the diameter of Tungsten or your using AC, where it should be a ball end.

How sharp should my tungsten be?
15° Point: This sharp tungsten grind angle is about as narrow as tungsten can be ground without causing serious issues such as splitting and spitting. Penetration is good for the level of amperage used.
How do you sharpen tungsten TIG electrodes?
0:030:52We'll be using a bench grinder because it's more common using the opposite end of the colored tipMoreWe'll be using a bench grinder because it's more common using the opposite end of the colored tip press the tungsten vertically on a thirty degree angle against the grinding wheel and rotate.
What is tungsten grinder?
tungsten grinder is a portable piece of equipment that is easy to operate and helps in the repetitiveness of the sharpening. Ideally but not always, dry electrode grinders will feature a “closed process” that limits exposure of tungsten particulates and sharpening powder to the operator.
What is the fusion point of tungsten?
Pure tungsten is a very heat resistance material with a fusion point of approximately 3,380 degree C. By alloying tungsten with a few per cent of a metal oxide the conductivity of the electrode can be increased which has the advantage that it can thereby resist a higher current load. The alloyed tungsten electrodes therefore have ...
What is the diameter of a tungsten electrode?
Tungsten electrodes are available in different diameters from 0.5 to 8 mm for TIG welding. The most frequently used dimensions for TIG welding electrodes are 1.6 – 2.4 – 3.2 and 4 mm.
How to grind electrodes?
22.5° is the most common angle for grinding electrodes. This angle will work for most situations. If you are grinding without a guide, you can find 22.5° this way: 1 Before you touch the rod to the grinder, hold it horizontal, perpendicular to the wheel. This is 90° 2 Slant the rod from horizontal halfway to vertical. Halfway between horizontal and vertical is 45° 3 Now slant the rod halfway again. It should be three-fourths of the way down from horizontal to vertical, or one-fourth of the way up from vertical. This angle is 22.5°, just right for sharpening the tip of the electrode
When to use angle grinder?
An angle grinder should only be used when you don’t have any other choices. If you are welding at someone else’s shop and don’t have access to your usual tools, an angle grinder will put a tip on the electrode. It’s hard to get a consistent angle and a clean grind, but it can be done.
How to sharpen a weld?
You need to choose a sharpening tool, then follow six simple steps. Cut or break off any contamination from touching the electrode to the weld pool. Use a dedicated, tungsten-only grinder or sander. Grind parallel to the length of the rod, never across it. Hold the electrode to the grinder wheel at an angle of 22.5°.
What tool is used to sharpen electrodes?
Bench Grinder. Bench grinders are probably the most common tool used to sharpen electrodes. If you are welding, chances are you already have a bench grinder. (If you are welding and don’t have a bench grinder , you need to get one.) Bench grinders are handy and will sharpen the electrode well.
What is the electrode used to weld metal?
After all, it is the tungsten electrode that transmits the arc from the welder to the metal. If your electrode isn’t set up correctly, you can’t get a clean, strong weld. For the best performance of the welding arc, the electrode is usually sharpened before welding. This process can be confusing for new welders.
What angle should the electrode be held to the grinder wheel?
Hold the electrode to the grinder wheel at an angle of 22.5°
What are the drawbacks of bench grinders?
Bench grinders are handy and will sharpen the electrode well. The drawbacks to bench grinders are contamination and distance. If you use the same grinder wheel for everything, you can contaminate your rod. The wheel will have bits of steel, rust, aluminum, and whatever else you have been grinding stuck to it.
