Johnson 50/50 Flux ‘N Solder is a combination flux and soldering paste containing powdered 50/50 tin-lead solder. Its rapid tinning action and relatively low melting temperature make it an efficient solution when you want to flux and tin the work surface in one step.

• The formula contains 50/50 powdered solder (50% lead), and therefore must not be used when soldering drinking water systems, food handling equipment, and livestock tanks
• Due to its relatively low melting temperature (360 to 420° F) and its rapid tinning action, this paste is excellent for soldering automotive components
• Residues are water soluble and should be removed after soldering
• Size: 1 lb net weight
