Which tends to be more usefull? I would lean towards the.welder since I.can use.it more ghan on the trail. Is it.possible to run.a york.and.weldernator(not at once) but both mounted.to the engine?
 
The only answer to a question like that is................................................................................




BOTH!!

If you had to choose only one I would choose the OBA long before a weldernator. How often do you need to make a field repair using a welder, how often could you see the need to air down and then need to air up before you hit the pavement? The OBA can also run air tools if you have a small air tank as reserve. You can also use the air to blow off parts that you might be working on as well.

Bascially, the welder can only be used for one thing (welding) but the OBA can be used for multiple things. Also the weldernator doesn't produce a "nice" weld but rather something to get you by until you can repair it properly.
 
I think on-board air would be more immediately useful. Air down, run the trail, air back up and go home :dunno:
 
I'd say an air compressor would be called into service a lot more often...but there is no reason both cant be run off the same engine either,its just the amount of room under the hood that will limit that possibly...

A weldenator CAN made very good welds,depending on how it is set up--if you use the DC output it will weld a lot better than a typical AC buzz box home welder,some guys use the three phase AC right off the stator bypassing the recitifier and diode trio and weld with the highrer 3 phase AC cvoltage,which is a lot more hazardous,but the high frequency makes for a lot better penetration and puddle control..
 
I carry a CO2 tank and a handful of welding rods and jumper cables.
 
OBA first, then Weldenator, then mounting

I am in the same situation now, but I started working on air first, a few weeks ago, currently I am working on creating a stable voltage supply for the weldenator. next I will work on the mounts. I figure why should I go through the hassle of mounting all of this stuff up if it's not capable of doing what I want to do with it. Attached is a test setup of one of my weldenator running at 250 rpm producing 46.6 amps.
