I agree with the posting below thw video.
You want to weld as HOT as possible to get full penetration . Don't listen to the guy in the video! His weld looked like crap. Also he mentions to dip your weld into water to cool it off. DO NOT DO THIS!!! Putting your weld in water will weaken the weld and the base metal. Let the weld cool naturally before you touch it. This guy on the video gave only a few "tips" on how to weld and most of them were wrong. I need a video of me on here.
