What angle do you sharpen tungsten?
To grind the tungsten properly and to prevent contamination, it is preferable to use a grinding wheel especially designed for tungsten grinding, resistant to tungsten´s hardness. Grind the electrode straight on the direction of the wheel at a 90° angle and make sure that the grind marks are lengthwise.
How far should your Tungsten stick out?
Because the best starting point for a tungsten stick-out is the diameter of the lens in 16th, simply extend the tip of the tungsten out about 1 1/2 inches, then lightly tighten the back cap. Then place the tip into the hole that corresponds with the number on the lens you are holding.
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.
What will grind tungsten carbide?
While this material is very hard, it does become worn over time and may require grinding or sharpening. Carbide tools and tips can be ground with a diamond grinding wheel, but grinding a tool evenly requires skill and practice.
How long does a TIG rod last?
As a general rule, welding rods that are kept in ideal conditions should last upwards of 3 years. The life of an electrode will vary by the material as well as manufacturer, but most recommend switching for new ones after five years.
Why does my tungsten turn 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 TIG welder melting my tungsten?
Too large of tungsten for the given amperage can cause the arc to rotate around the tip, while too small of tungsten can melt and cause the arc to become unstable. Always follow the manufacturer’s recommended welding parameters for each tungsten electrode diameter.
