Arc Welder

The arc welder is a weapon in the Fallout: New Vegas add-on Lonesome Road.

Background
The arc welder is essentially a electrostatic discharge gun using electron charge packs, capable of shooting a constant, high-voltage stream of lightning much like flamers with fire. It does bonus damage against robots and power armor wearers and seems to have been designed to be a weapon rather than a tool.

Characteristics
It's an excellent weapon against robots and power armor wearers at any level, but it does average damage against high-level enemies. It turns enemies into ash piles on a Critical Hit.
