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.
