How did the metal head guy get electricuted fighting Jim West?
I read another post on here about the same topic but I didn't see any real answer. So wanted to bring it up again. Towards the end while on the spider Jim West fights these guys, one of them appeared to be made out of metal or iron or whatever. Jim West hits him with a big wrench a few times, then he hands the guy the wrench, the metal head guy holds the wrench in the air and then yells, sparks fly from what I assume is from some sort of electrocution, and then he falls off the spider.
The previous post mentions there are some wires overhead and he touched them with the wrench and that fried him, but I watched that scene several times and there are no wires above him. Someone mentioned maybe hitting the metal head guy several times made him short circuit when he took the wrench, but I believe he was wearing gloves, outside of that the wrench doesn't touch the guy at all.
So what could it have been? It seem Jim West knew someone was going to happen, otherwise why hand him the wrench to bash Jim West with? Jim West also immediately stepped to the side, like he knew this was going to happen. So any further explanations on this?
