Big gap between pipes in TIG welding root pass

Hello everyone.
Today I did "ROOT PASS" on a pipe with a wide gap.
This technique can be said to be the most basic content when TIG welding a large gap.
This method can be applied in various situations.
It can be applied in vertical welding, horizontal welding, overhead welding, and 5G position.
I'll show you those things later.
Thanks for watching.
Best wishes for a Happy New Year.
