Lastek 3204 IS

Flux cored soft solder for general use

Very easy, thin flowing soft solder with low melting point.

High tensile- and shear strength.

Suitable for delicate work, using a soldering iron or soft flame.

Applicable on stainless steel, steel, copper, zinc, lead, nickel, cast iron, galvanised steel.

Specifications & Usage

Application

Joints in cooling installations, jewellery industry, musical instruments, bird cages, radiators.

The aggressive flux in the core makes Lastek 3204IS not suitable for electronic applications.

Melting temperature: 183 - 188 °C (360 - 370 °F).

Instructions

To obtain maximal strength, soldering gap has to be between 0.08 to 0.15 mm.

Degrease the pieces to be joined. Slightly preheat with a soft flame. Melt the solder by striking the solder along the gap.

Can also be used with a soldering iron: when the solder is pressed on the iron to melt it, the flux could become inactive; so apply the solder on the parent metal and press the soldering iron on the solder and the joint.

Remove flux residues with hot water.

Work in a well-ventilated area.
