I have read a couple of types for welding tools but I cannot see it matches any type.

From what little is shown, it's a TIG welder hand torch, being used without welding rod. One does not typically allow the tungsten tip to contact the work (2:26), as it did in the video, welding itself to the work piece. Such action is poor practice. Poor practice also includes the lack of eye and skin protection.
The shape of the hand torch will vary from manufacturer to manufacturer:

I figured it out that the welding in the video is a TIG welding tool, but that's not the end as there are 3 types of TIG welders.
Scratch start, Lift/Jump start and HF(High Frequency) start. If you'd like to know more about what the differences are, Google search will find you a lot, but here is what I found.
So how to tell what types of TIG the guy used in the video? We can tell that by watching how he operates the welder torch.
As these 3 types of TIG names suggested, HF start TIG can initiate the electric arc without scratching or touching and lifting. So the type of TIG welder the guy used in the video is HF TIG welder. The Scratch start and Lift start TIG have different ways to initiate the electric arc to weld.
It's a TIG welding hand torch. This article explains it well.
