MoW: Track Welders

Wayne Helms posted in Facebook

I saw two different types of welders posted in Facebook within 24 hours of each other. Both of these are arc welders that use an on-board generator set to send a lot of amps through the metal to be molten.

In the case of the Chemtron CAT below, note the railroad wheels that can be lowered so that the unit can travel down the track. The "box" on the rear of the cab is the engine and generator for the weld head that is hanging from the boom.

A video of one in action  There is another video down in the comments. That video has a lot more sparks. Comments are asking what is wrong with the unit in the original video.
