A 10% sulfuric acid and hot water solution applied with a stainless steel brush will give a clean, more polished appearance. Allow the part to air cool and remove all slag using a stainless steel brush before making additional passes. Very easy to use with an exceptionally stable arc, operating at low amperages with a very minimal amount of spatter or fumes. Smaw E4043 Welding Rods 5% Silicon Aluminum Arc Welding Electrode - Welding Electrodes and Instructions: Clean the weld area thoroughly so it is not contaminated with iron, rust, oil, grease, etc. Align the parts to be welded by tacking the joint(s). Thicker sections should be beveled to a 60° Vee. ***READ THIS: The images are for reference only. Oxygen Tank 400g - 2.4mm E4043 Aluminium Stick Electrodes Dowsing Rods Commonly used on irrigation piping systems, refrigeration equipment, appliances, boat parts, ornamental aluminum parts, aluminum door or window frames, aluminum ladders, tanks, shelves, automotive, trucks or bus parts, machining errors, and building-up missing sections on castings, extrusions, and plates. When finished, allow the part to cool down to about 200°F and remove flux residue with warm water and a stiff stainless steel brush. Description Blue Demon E4043 is a general-purpose aluminum electrode for arc welding aluminum alloys. Notes: When using an oxyacetylene torch to braze, set torch to a carbonizing flame and carbonize the part, then readjust to a neutral flame and heat the entire part until the carbon residues fade; then apply E4043. SÜA - E4043 is used for production or maintenance and repair welding on all weldable grades of aluminum sheets, plates, pipes, castings, and extrusions with a minimum of 3/32” thickness. These Electrodes are 14 inches long and are available in Sizes: 3/32, 1/8 and 5/32 - Available Packages: 0.5 Lb, 1 Lb and 2 Lb - Select your option from the Size Menu - Check Picture #2 for an approximate number of electrodes per pound.
