Product Information

Full details

The Navigator Lead Free Solder Wire is an essential tool for plumbers, heating engineers, and DIY enthusiasts who need a reliable, regulation-compliant solution for copper pipe and fitting assembly. Designed for use in potable water systems, this solder wire delivers high-strength, watertight joints through excellent capillary action, though its specific 3.25mm thickness makes it less suitable for delicate electrical work.

FAQs

Is this solder safe for drinking water pipes?

Yes, this wire is lead-free and specifically designed to be safe for potable water systems.

Can I use this for electronics?

No, the 3.25mm thickness is far too large for electronics, and the melting point is not suitable for sensitive components.

What temperature does it melt at?

The solder has a consistent melting point of approximately 227°C.

What materials does it work on?

It is optimized for copper and brass pipework.

How should I store the spool?

Keep the spool in a dry area and ensure it is kept away from moisture to prevent oxidation of the wire surface.

Troubleshooting

Solder is not flowing into the joint

Ensure the pipe and fitting have been cleaned with abrasive wire or pads to remove oxidation and that the metal is heated evenly to 227°C.

Solder bead is brittle or cracking

The joint was likely moved while cooling. Ensure the pipe is fully supported and stationary until the solder has completely solidified.

Joint is leaking after cooling

This may be due to insufficient heating or debris in the joint. Clean the joint again, re-apply flux if necessary, and ensure even heat distribution.

Pros and Cons

Pros

Safe for use in drinking water systems
Excellent flow and capillary action for plumbing joints
Strong, durable bonds on copper and brass
Easy-to-handle 500g spool format

Cons

Not suitable for micro-electronics or PCB repair
Requires higher heat threshold than lead-based solders
3.25mm thickness is too large for fine soldering

Setup, Compatibility & Care

To ensure success, use an appropriately sized propane or MAPP gas torch to achieve the required 227°C melting point. This solder is strictly intended for plumbing and pipe fitting; it is not recommended for electrical or electronics soldering.

Store the spool in a cool, dry place away from direct chemicals. When working, always wear appropriate safety gear, including heat-resistant gloves and eye protection, as working with open flames and high-temperature molten metal carries inherent risks. Ensure the workspace is well-ventilated during the soldering process.
