Review: Electric soldering wire - Haven't this used yet but looks great overall. Just a matter of time tho
Review: What is says on the tin - The solider wire is as described the thickness of the wire is 0.6mm and weighs 50g. I have used this wire to practise soldering and like all wire is easy to use and melts around 200c, however I have found the solder flows better above 230c on my iron. The bond created appears strong as I have used it to attach the correct colour indicators to my e-scooters indicator light board and have hit a few speed bumps, uneven road surfaces, and bumpy trails so is durable.
