Used to weld many similar and dissimilar, cast and wrought aluminum parts, 4043 aluminum is a 5 percent silicon aluminum alloy wire used extensively in electrical welding processes. Key parameters of the welding process, such as wire feed speed and required voltage power, differ among different welding processes (ie, MIG vs TIG), among different aluminum part thicknesses, and among varying wire diameters. As always, when welding, use common sense precautions to protect yourself from flying sparks and hot metal.
Instructions
1. Feed the 4043 aluminum wire to the welding torch. Insert wire through the guide tube and over the roller. Align it with the hole at the end of the wire liner, and push it manually into the hole for a few inches.
2. Tighten the wire, with a tensioner.
3. Adjust the wire speed and power settings of the torch, following the manufacturer's instructions. As wire diameter increases, voltage requirements increase, as does, in general, required wire speed. Voltage requirements also vary between different kinds of welding (ie, MIG vs. TIG).
4. Fire the torch. Move it in a zig-zag motion over the surface of the metal to which you are welding. If you are welding thick metals or wires, consider using a zig-zag motion in a relatively straight line; if you are welding thin metals or wires, use a curved zig-zag motion. Consult your manufacturer's instructions for details on the specific motion.
Tips Warnings
Wear a protective mask, gloves, thick clothing, goggles, and rubber boots to protect yourself while welding.
