It looks an awful lot like my Sieg C6B, which as shipped has an 800W motor
but only a single speed range of 0 - 2000.
Make sure you know how much grunt you want and can get out of this machine
at the bottom end - you might find (I don't know this is true of the Wm-250)
that it runs out of grunt below 125rpm. I've added a 0 -500rpm range to my
Sieg for that reason.
I don't have a great experience of variable speed DC motors but I do worry
about a heavy load on a motor thats only turning at 5-10% of max speed from
a cooling point of view. Some say I worry too much!
I didn't buy the 918, because I wanted a machine with not necessarily more
features, but definitely as much rigidity as I could get and the SIEG was
on offer at the time and so cheaper than the Warco. I have bought Warco
before and they are "real" they know what they are selling and you can talk
to them.
Best Regards
Steve
