Weldcote Liquid Soldering Flux Is A Water Based, General Purpose, Inorganic-Acid Flux Formulated For Soldering Stainless Steel And Other Industrial Metals. The Flux Contains Zinc Chloride, Ammonium Chloride And Hydrochloric Acid, That Makes This Flux Active At Room Temperature Where It Begins To Clean Metals And Remove Oxides. The Flux Exerts A Strong Scavenging Action To Remove Oxide Coatings And Other Impurities From The Metal Surface To Produce Strong Joints. Pre-Cleaning Is Not Necessary Under Most Conditions. Weldcote Liquid Soldering Flux Is Excellent For Use On Stainless Steel, Monel, High-Chrome Alloys, Inconel, Nickel, Copper, Brass, Ferrous Alloys And Many More Metals. It Is Not Recommended For Aluminum And Magnesium. Procedure: Weldcote Liquid Soldering Flux May Be Applied With A Brush, Swab Or By Dipping. The Flux Exhibits The Best Activity Between 93-315 Degrees Celsiuis/200-600 Degrees Fahrenheit. Post-Solder Residues Are Water-Soluble And Hot Water Rinses May Be Adequate For Most Applications. The Following Steps Are Recommended For Optimum Soldering Results. Remove Any Oil, Grease, Or Other Contaminants From The Surface To Be Soldered. Apply Flux To Joint By Dipping, Spraying, Dragging, Swabbing Or Brushing To Area Being Soldered. Preheat Or Air-Dry Area To Be Soldered After Flux Has Been Applied To Activate The Flux And Yield Optimum Soldering Characteristics And Reduce Or Eliminate Spattering. Apply Solder, Dip Part, Place Torch Or Iron To Area Being Soldered. To Insure Complete Removal Of Flux Residues, First Use Water Ocntaining 2% Hcl Followed By As Many Hot Water Rinses As Necessary.
