Solder Pot (150W)

The SS-551 is a compact 150 W round solder pot with a solder capacity of approximately 0.3 kg. It is mainly used for tinning wire ends, dip-tinning small components, and low-volume soldering processes. Its compact size makes it suitable for small-batch work on electronics production lines, in repair, model making, and home DIY projects.

The SS-551 has a pot size of Ø38 × 35 mm and a capacity of approximately 0.3 kg, making it more suitable for small components, wire ends, and intermittent low-volume dip-tinning. For higher production volumes, larger workpieces, or greater solder capacity, consider the SS-552, SS-553, or SS-554.

The SS-551 is rated at 150 W, has a temperature-control range of 100°C to 600°C, and holds approximately 0.3 kg of molten solder. Set the temperature according to the solder alloy, flux, workpiece size, and production pace. Avoid maintaining the highest temperature unnecessarily for extended periods.

The SS-551 uses an AISI 201 stainless-steel solder pot with titanium plating, which improves corrosion resistance and high-temperature performance for repeated heating and solder-melting operations. Avoid incompatible corrosive materials and tools that may scratch the coating, and inspect the pot surface periodically according to usage conditions.

Yes. Official information states that the SS-551 can be used for both leaded and lead-free processes. Because solder alloys have different melting points and oxidation characteristics, thoroughly clean the pot when changing materials, avoid mixing alloys, and adjust the temperature and flux according to the alloy recommendations.

Under the maximum setting, the official comparison table lists a solder-melting time of approximately 10 minutes for the SS-551. Actual time depends on the amount of solder added, initial temperature, solder alloy, and ambient conditions. Before starting work, confirm that the solder has melted evenly and reached a stable temperature.

There is no single fixed temperature. Set it according to the solder alloy's melting point, the workpiece's thermal mass, and the flux conditions. As a general rule, use the lowest effective temperature that provides stable wetting without excessive oxidation. A temperature that is too low causes poor tinning, while excessive heat accelerates oxidation and shortens solder-pot life.

Remove oxidized solder dross from the surface periodically during operation, and use the stainless-steel waste-solder tray for temporary collection and recycling. Do not scrape the titanium-plated surface forcefully with sharp tools. Before shutdown, handle the molten solder according to the applicable safety procedure, and clean the housing and surrounding area only after the unit has cooled.

Official information indicates that the SS-551 may also be used to melt certain materials that readily solidify at room or low temperatures, such as specific adhesives or grease-like substances. Before use, confirm the material's suitable temperature, volatility, flammability, and chemical compatibility. Never place food or unidentified chemicals in the solder pot.

Choose according to pot size and molten-solder capacity. The SS-551 holds approximately 0.3 kg and is suitable for small-volume work; the SS-552 holds approximately 0.5 kg; the SS-553 approximately 1.6 kg; and the SS-554 approximately 2.2 kg. A larger capacity is not always better; also consider workpiece size, output volume, heat-up time, and available bench space.
