this adapts a 10 pound spool to fit on a spindle meant for 1lbs spools(or different versions of 10lbs spools), but has more than enough space to fit a 10 pound spool.
currently works with the nr-211-mp wire. product number #ED033130

this may work for a 25/30 pound spool too, if it uses the same type of spool.

fits on my Miller Weld-Pak 100.

if it fits on your welder, let me know and i'll add it to the list here.
