This auction is for 20pcs Aluminum Solution Welding Flux-Cored Rods Wire Brazing Rod

Specifications:
Length 50cm
Optional Diameter: 2mm
Features:
1. Suitable for welding or surfacing welding alloy with high strength, good forge ability & good corrosion resistance.
2. Made of aluminum material, non-toxic, odorless, and durable material.
3. There is no need to use other flux powder with aluminum alloy as the welding core and coating as the salt base.
4. Include welding filler wire and spray and flame metalizing wire. It is also used for argon arc welding and filling material for pure aluminum, connection with aluminium bus and guide rod of electrolytic aluminium plant and electric power, chemistry, food and so on.
5. Designed with full & smooth welding effect because the item comes with internal powder, great weldability and corrosion resistance, high thermal conductivity, high electric conductivity and excellent processing performance.

Usage:
1. Clean and polish the physical surface.
2. Heat the surface of the metal material until the temperature of wire is up to the working temperature 380 to 400 degrees.
3. The aluminum base metal is heated to the appropriate working temperature when repairing thin aluminum, and then use the wire friction and melt to form a weld.
4. Use propane gas to weld small object and use industrial gas or induction heating device to heat and weld big one, you should cool it naturally after welding.

Please Note:
When using Oxyacetylene welding, neutral flame welding should be used, but please do not burn the wire directly.
Applicable Heat Source: Such as propane, oxyacetylene, and so on.
The base metal temperature should reach 400 degrees, including the process of welding the base metal temperature should be maintained at 400℃, and the temperature can be high or low.
Professional use is highly recommended.
