Normally the reason certain weld processes aren't permitted is based on weld quality. I seem to recollect that short arc welds tend to be brittle. You might want to check at the Lincoln <http://www.lincolnelectric.com/> web site to see whether short arc is recommended for low temperatures or whether there are guaranteed Charpy values for shrt arc welding. That'd be the giveaway.
