Features:<br> brand new and high quality<br> In the range of 620-850 degrees, and with silver -based solder, silver brazing copper and copper alloy, copper and stainless steel, can effectively dissolve the various metal oxides, fueling solder overflow.<br> Function:<br> 1. Melting, covering, isolating, preventing oxidation<br> 2. Clean the surface of weld<br> 3. Participation in flow brazing/puddle welding<br> Cautions:<br> 1. Clean oils, oxides and other contaminants of brazing components and solder surface .<br> 2. Before welding, workpiece must be preheated to about 500 degrees and electrode coated with an appropriate amount of brazing flux .<br> 3. After welding, cleaning welds, prevent corrosion of residues solder flux.<br> 4. It should be stored in a dry place, against damp.<br> <br> Welding operation:<br> 1. Mix the welding powder with pure water to paste.<br> 2. Apply paste to the mouth of welding workpiece, or pre-heating the brazing and soldering alloy first.<br> 3. Use the brazing and soldering alloy stick with the welding powder. The welding for gap could not too big. It is normally 0.01-0.05mm.<br> In the flame brazing, usually to use neutral welding. In the operation, should to avoid to use the flame to heat the brazing & soldering alloy and the welding powder.<br> <br> Specification:<br> Net weight: 100g<br> Color: White<br> Quantity: 1 box<br> <br> Note:<br> Transition: 1cm=10mm=0.39inch<br> No retail package.<br> Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid.<br> Due to the difference between different monitors, the picture may not reflect the actual color of the item.
