Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
I have seen some in the old, old style large welding trailers.
THere is a good bit of information on the web about these generators, with many people swearing by them.They do make good generators, but they do not tolerate light loads well.
If I was not so far away I would like to see them.
I know where several 2-71 powered military welding trailers are, they were built in 1962 and 1966. Unfortunately they are in scrap condition and the seller wants $1200 each.
I've also seen a 3-71 powered centrifugal pump on a military trailer....
I would bet that your unit is actually made by Hobart... Maybe the data plate is faded or has some damage that makes it look like "Holgart" instead of "Hobart" but Hobart is a popular brand of generators and welders.no one knows who holgart is
The 2-71 gensets that used to power virtually all railroad refrigerator cars were de-rated... They ran at 1200 rpm and used special injectors so that light loads would not cause problems... These injectors could be used to advantage on an 1800 rpm unit that ran light a lot.Run them at 1800 RPM and 10% load for hours and you won't have a happy engine.
