12Pcs Brass Brazing Rods, Phosphor Copper Solder, Low Temperature Welding Sticks 1/16"x20" for Copper Repair

What is this?
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.

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.

How to use it?
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.
