OVERVIEW

Achieve Professional Brazing Results with Weldcote White Paste Flux

For welders, plumbers, and metal fabricators, the quality of the flux can make or break a silver brazing project. Weldcote White Paste Flux is designed to take the headache out of brazing by providing a smooth, consistent, and reliable medium for your filler metal. Whether you are repairing a delicate HVAC line, fabricating custom stainless steel parts, or joining brass fittings, this 1lb jar of white paste is the trusted companion for your oxy-fuel torch. Its primary job is to clean the metal surface chemically as you heat it, removing oxides and creating a path for the silver solder to flow deep into the joint.

One of the standout features of this flux is its user-friendly consistency. It comes as a creamy white paste that is easy to brush onto your parts without dripping or running off prematurely. Furthermore, Weldcote has formulated this product to resist the common problem of drying out; it won't turn into a hard, unusable rock in the jar, retaining its smooth texture for up to two years. As you apply heat, the flux becomes transparent, giving you a clear visual indicator of the temperature and the cleanliness of the joint, allowing you to add your filler rod at the perfect moment.

The flux is active up to 1,600°F, covering the melting points of most standard silver brazing alloys. It works exceptionally well on copper, bronze, brass, steel, and stainless steel. Once your work is complete and the metal has cooled, you won't need harsh chemicals to clean up. The residue left behind is water-soluble, meaning a simple scrub with warm water will leave your joint bright, clean, and professional. Upgrade your brazing game with a flux that works as hard as you do.

FAQ

This flux is designed for use on copper, brass, bronze, steel, stainless steel, nickel alloys, and carbides. It is not intended for use on aluminum or magnesium.

The flux remains active and protective up to approximately 1,600°F (870°C). If heated beyond this point, the flux may burn out and lose its effectiveness.

Because the residue is water-soluble, you can clean the finished joint by scrubbing it with hot water and a wire brush or rag once the part has cooled down.

Weldcote White Paste Flux is formulated to resist crystallization and hardening, offering a shelf life of up to two years if the container is kept sealed when not in use.

No, this is a brazing flux designed for high-temperature silver brazing alloys. For soft soldering (lead/tin), you would need a different type of flux active at lower temperatures.

Yes, the creamy consistency allows it to be dispensed via automatic spraying or dipping systems often used in production brazing lines.

As you heat the base metal, the white paste will eventually turn into a clear, liquid fluid. This indicates the flux is active, the temperature is rising, and the joint is nearly ready for the filler metal.
