Orange Mini Fiber Optic Wattmeter: Fast, accurate, sensitive, robust and compact optical tester (-70 to +10 dBm)

Function:

1. It can weld copper, steel and hard alloy materials at temperatures ranging from 890℃ to 905℃.
2. Containing a small amount of tin and silicon, tin can improve the fluidity of the wire, and silicon can effectively control the evaporation of zinc.
3. Good mechanical properties, good wear resistance, excellent fluidity, suitable for cold welding without temperature.
4. No need for solder powder - You don't need to use another flux powder with brass as solder core and coating as salt base. Very practical and easy to solder.
5. Light weight, small volume, very easy to carry.

Note:
1. The weld bevel and wire surface must be thoroughly cleaned before welding.
2. Preheat to 400-500℃ before welding. Copper gas welding solvent must be used during welding.
3. The welding flame should be neutral or slightly oxidizing, appropriately reducing the temperature during welding, increasing the welding speed, minimizing the residence time of the high-temperature weld pool, and thus reducing zinc evaporation and oxidation.1.6 mm × 250 mm Brass Solder Wire (Optional)
