Fixes a DIFFERENT error in welding code. (#4995)

* fixes the ears i made ten  minutes ago, oops./

* reduces welding damage

by about half. It's still gonna be REALLY REALLY BAD to weld without protection due to the way the injuries progress even when fixed but this should at least prevent eyes from being instantly turned to ash on single unprotected weld.

* Revert "fixes the ears i made ten  minutes ago, oops./"

This reverts commit 11f3281.

* lol
