// 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.
