Description

Specification:

Material: BCu93P phosphor copper.

Colour: copper.

Size: 3 x 1.3 x 400 mm.

Quantity: 20 pieces.

Instructions for use:

1. Clean or extend the surface of the pipe fittings to be welded. The extended speaker mouth should be smooth, round, without burrs and cracks and evenly thick. Clean the connection of the copper tube to be welded with sandpaper and finally wipe it with a dry cloth. Otherwise, the solder flow and welding quality will be affected.

2. Insert the copper pipes to be welded overlapping (note the size) and align the centres of the circles.

3. When welding, the parts to be welded must be preheated. Heat the welded connection of the copper pipe with a flame. When the copper tube is heated crimson, remove the flame and place the solder at the welding point so that the solder melts and flows into the welded copper parts. The temperature after heating can be reflected by the colour. The temperature level.

Please note:

1. Before soldering, grease, oxides and other impurities must be removed from the soldering area and the surface of the soldering material.

2. When brazing copper, there is no need to use solder solvent. However, silver flux should be used when brazing copper alloys.

Package includes:

20pcs x Phosphorus Copper Welding Rods
