Weller Wire, 0.8mm Lead Free Solder, +217 → +221°C Melting Point

Introducing lead-free solder wire from Weller, designed for use in electrical and electronic applications and to be environmentally friendly. Once your iron is at the required temperature the solder wire tins, flows and solidifies well. The WSW SAC M1 solders have been developed to meet the electronics industries' increasingly stringent quality requirements.

Solder is used alongside soldering irons, particularly in securing electrical components to integrated circuit boards. The solder melts easily when heated, and cools quickly, meaning it can be moulded to secure components in place in solder joints. The quick setting nature of solder means it can also be used for light brazing.


Because of its relatively low melting point, solder can be reworked easily by heating it to a melting point and using a solder sucker to remove it.
Solder is commonly used with SMD and through-hole components, with applications in repair, prototyping, and production.

What is soldering used for?

Solder wire forms a connection between electronic components. Solder is heated, and melts using a soldering iron and then melts into a connection.


What is solder made of?

Typically, 60% tin and 40% lead. 60/40 is the most commonly used type of solder for hand soldering. Solder that is made of 63% tin and 37% lead. 63/37 solder is also known as eutectic solder and is often preferred because it goes directly from a solid to liquid state when melted.


Types of solders?

Electronics solder – lead alloy, lead-free, silver alloy.


What metal cannot be soldered?

Stainless steel and high alloy steel unless pre-plated in a solderable metal.
