XLS generator wattage

The reason I asked for the wattage rating of the generator is that the generator will easily provide more wattage than its rating but, as Sepixlh points out, not for long. When it is working too hard, it will begin to melt the solder in the commutator and render the armature virtually irretrievably broken. That's why the answer I got regarding minimum current is worthless -- I already knew my generator was working "correctly" -- and my concern is not for the minimum, but the maximum. (Sepixlh, thanks for the note that it will produce 17 amps, with the implicit note that it ain't a good idea)
How I now it... better don't ask how it happened :-) OK I was testing one "broken" generator and noticed that there is 2 differend kind of field coils. Other was producing 14 amps @ 2700rpm before saturation. Other was outputting 20 amps @ 2600rpm before armature decided that this is enough. As halmc wrote soldering start melting -> one coil end brake loose and penetrate between brush and brush holder -> holder brake loose and fly between poleshoe and armature -> generator became totaled
