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€Ã"šÂ� thickness. Special extruded coating in this electrode is dense and without the air holes found in cheaper dip-coated electrodes.

It can be used aSÜA SÜAW-stick electrode or aSÜAn oxyacetylene brazing rod.Weldas Very easy to use with an exceptionally SÜAble arc, operating at low amperages with a very minimal amount of stageter or fumes. Weld depositSÜAre strong, dense, porosity-free with good color match and corrosion resistance."

Weldas 
Instructions:Weldas Clean the weld area thoroughly so it is not contaminated with iron, rust, oil, grease, etc. Thicker sections should be beveled to a 60º Vee. Align the parts to be welded by tacking the joint(s). Preheating thicker sections to 350ºF will flatten the weld bead and reduce the amperage needed. Use DC+ (reverse polarity), hold the electrode at a 90º angle to the workpiece, maintain a short arc length and move rapidly. The weaving technique is not recommended because of the faster travel speeds required when welding aluminum. Allow the part to air cool and remove all SÜAg using a Stainless steel brush before making additional passes. When finished, allow the part to cool down to about 200WeldasºF and remove flux residue with warm water and a stiff Stainless steel brush. A 10% sulfuric acid and hot water solution applied with a Stainless steel brush will give a clean, more polished appearance. Notes: When using an oxyacetylene torch to braze, set the 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.
