How to prepare you tungsten for TIG welding

June 10, 2020

In this video, we explain how to set up your tungsten electrode for TIG welding.

Today we are going to show you how to prepare your tungsten. We will be using a 2.4mm Lanthanated tungsten electrode for this demonstration as it can be used on both ferrous and non-ferrous metals with the same preparation…and the time starts now.

Firstly, you will need a tungsten grinder or a bench grinder, we will be using a bench grinder as it is more common. 

Using the opposite end of the coloured tip, press the tungsten vertically on a 30-degree angle against the grinding wheel, and rotate in a consistent motion until you achieve a fine point.

The reason you grind with the grain, not against the grain, is because it will stay sharp for a longer duration of time, and the arc will stay more focused and stable resulting in a narrower, neater weld.
