Why does my TIG electrode melt? Welding Mastermind

A thicker tungsten electrode can resist a higher heat input. So if you have looked into all the other above mentioned areas, increasing your tungsten electrode diameter might prevent your tip from melting. For example, if you are currently using a tungsten size 1/16 you might consider moving one size up to 3/32.

Pouring Tungsten Jigheads and weights Wire Baits

Oct 16, 2016 Tungsten can actually be melted using an arc-furnace. If you're very clever, you could possibly make a tungsten-melting arc-furnace out of an old stick welder-- this has been done by hobbyists to melt very-high-melting-point metals. However, once you did get it melted, you really couldn't do anything with it. You'd just get a small blob of

Tungsten carbide Wikipedia

Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing shells and jewellery.

Identifying and solving tungsten electrode and arc issues

Jul 18, 2002 Tungsten is a non-consumable electrode that has the highest melting point of any metal (3,410 degrees Celsius or 6,170 degrees Fahrenheit). So in theory it can’t melt, right? Wrong. One of the most common tungsten troubles is excessive consumption. On AC (alternating current) applications, such as TIG welding aluminum, setting the balance
