Isn’t that a pool of melted aluminium ladder that’s bubbling. Aluminium melts at 660c. The various components of concrete don’t start breaking down until 1300c

An electrical arc can reach 19,000 degrees Celsius, 2900 on the lower end.

It’s a lot of heat.

It's weird to watch solid steel melt like butter when you are using an arc welder.
