SANHA solder paste LUT MIEKKI 2.5 mm 250 g
SANHA solder paste LUT MIEKKI 2.5 mm 250 g is a combined flux and filler designed for joining and brazing copper and similar metals in plumbing and HVAC systems. Packaged in a 250 g container and formulated with a 2.5 mm particle size, this solder paste is intended to simplify on-site soldering tasks by providing both active flux and metal alloy in a single product. The paste supports capillary flow and joint formation for conventional soft soldering and brazing processes used by professional installers and maintenance personnel.
The product integrates flux and filler material, reducing the need to handle separate components during soldering. Its 2.5 mm particle size balances workability and control for typical pipe and fitting joints. The paste consistency helps retain solder at the joint area, improving material efficiency and minimizing drips. Formulation is suitable for common heating and plumbing metals, enabling consistent wetting and reliable joint formation when used with appropriate heating equipment.
Prepare the joint surfaces by cleaning and degreasing to ensure good wetting. Apply an appropriate amount of the solder paste to the joint so that the paste fills the gap where solder is required. Heat the joint evenly with a suitable torch or heating tool until the solder flows and forms a continuous fillet; avoid overheating. Allow the assembly to cool naturally and, if necessary, clean off any residual flux according to local practices and material compatibility.
Use adequate ventilation and appropriate personal protective equipment during soldering. Select a heating method and temperature suitable for the pipe diameter and material. Test compatibility with the base metals in a small area if uncertain, and store the paste in a cool, dry place to maintain consistency.
