Thanks, Wolfgang and Zig! So, if it is a hot wire cutter, then why does
it have an adjustable arm? My guess is that depending on the type and
size of wire used, different lengths are needed so that the wire gets
hot but does not burn in two. Whadya think?

I recently acquired an older piece of equipment that I am not exactly
sure what its original purpose was for. When plugged in and a piece of
wire attached across the connections shown in the picture posted,
current flows through the wire and heats it up to the point it melts.
Or, if there is a break in the wire and the two open ends are brought
close enough together, then sparks fly for a second until a new break
has been established and the current stops flowing. It was manufactured
by Fisher Scientific Company, but their techies have not been able to
help me yet. Anyone recognize this piece of equipment? Thanks! Happy
Holidays!
