How to use a DC Lift Arc TIG Torch!

In this episode, we show you how to use a Lift Arc TIG Torch, going over the right technique to operate the torch, and how to remedy any common difficulties.

Firstly, Lift Arc TIG Torches are designed for DC welding, not AC welding.

The proper and easiest way to use a lift arc is to firstly lean the shroud on to the workpiece on a 45-degree angle, and in one motion move it up to 90 degrees as the tungsten electrode touches the metal, now lift it off about 3mm to initiate the arc.

If the tungsten gets stuck then you might get a tungsten inclusion, which will require you to re-sharpen your tungsten electrode, and grind back the metal so that you don’t end up with a weld defect at the start of your weld.
