//  Clean the end of the Ni-Cr wire with steel wool.  Slide a short lenth 
of copper or brass tubing over the end of the wire.  Heat Joint and 
remove heat.   Apply JW Harris acid flux flux for stainless steel to the 
heated joint.  This causes the flux to boil and activate.   Solder with 
6%-Ag/94%-Sn solder [430ºF].  Wash off flux residue with warm running 
water and a toothbrush.  /  For Ni-Cr ribbon, punch a hole wirh an awl, 
insert Cu buswire in hole.  Bend buswire over and solder as above.  Need 
these materials?  See my Web page's price list.
