ah, the old yard stick duct tape soldering iron trick....
I'm intrigued - is the other end mounted in the vise?
certainly looks that way.
My guess is that mr flave was applying pin point heat to an action screw.
A lesser man would have settled for simply holding the soldering iron to the fastener with his hand....
But, the lesser man would then not be free to drink bottles of "faceplant" with one hand and GFY himself with the other hand while the action screw heats up.
