Product Information
- The HVAC tools and equipment are used for brazing copper in motors, air-conditioners, meters, and refrigeration industries. Brass brazing rods is used for welding copper alloy, carbon steel and alloy steel. It can also be used as an inlaid carbide tool or DIY decorate. The low-melt solder is widely used for DIY craft drift punches knife handle lathes.
- Size: 3 mm x 250 mm/0.12 inch x 9.84 inch (Dia*L); Welding Current: 90-220(A); Melting Point: 890~905℃/1634~1661°F; Color: Bronze Tone; Style: Round Straight Bar; Material: Tin Brass(S221); In the package of: 6PCS x Welding Rods
- This brass welding rod is a special brass welding rod containing a small amount of tin and silicon. Tin can improve the flow ability, strength, and corrosion resistance of welding rods, while silicon can effectively control the evaporation of zinc, eliminate gas holes, and achieve satisfactory mechanical properties.
- 1.Clean the surface of the copper material to be welded; 2.Insert the stick into the welding gun or pen, and adjust the welding current and power as needed; 3.Contact the welding stick with the copper material to be welded to melt the contact; 4.Remove welding slag and remaining stick after cooling.
- Manual measurement, please allow slight errors on size. Before using these brazing rods, please keep proper ventilation, adhere to recommended temperature ranges, and wear appropriate safety gear during use. Before welding, it is generally necessary to preheat to a temperature of 400-500°C before welding. It must be used with copper gas welding solvent or gas solvent when welding.
