Revert the Welding Nerf

[Jakson]

I personally think the entire welding nerf was unnecessary for an issue that rarely showed up, and now it discourages quick thinking using lockers and crates to trap someone in. There's nothing more funny then slipping someone into a crate, and then welding them in, now that makes it impossible, and it was my go-to strategy for using the trash compactor to kill people without having to grab stuns.
