The Hobart Maxal 4943 Aluminum MIG Wire is a top - notch choice for welding. It's similar to 4043 but offers significant upgrades, with 50% higher yield strength and 25% higher tensile strength. Ideal for a wide range of applications including radiators, air - conditioning parts, automotive and motorcycle frames, aerospace hardware, ladders, frames, and ship decks. Like 4043, it works with 100% Argon shielding gas and can weld at a rate of about 14 - 24 inches per minute. The MAXAL MIG wire comes with numerous benefits such as a low melting temperature for high fluidity, minimal welding smut and discoloration, low ductility, full post - weld heat treatability, excellent corrosion resistance, a low shrinkage rate, and low hot cracking sensitivity.
Using the Hobart Maxal 4943 Aluminum MIG Wire is straightforward. First, make sure you use 100% Argon shielding gas as it's required for this wire. When welding, expect it to lay down at a speed of around 14 - 24 inches per minute. For best results, clean the welding area before you start. As for safety, always wear proper welding gear like gloves and goggles. After welding, you can heat - treat the piece to enhance its properties. To maintain the wire, store it in a dry place to prevent corrosion. Avoid exposing it to moisture and extreme temperatures. If you notice any signs of damage or degradation, replace the wire.
