Aluminum MIG welders are a popular choice for welding aluminum materials due to their versatility and ease of use. These machines use a wire feed system to supply a continuous stream of filler material to the weld joint. The aluminum wire is fed through a spool gun or a push-pull gun, which helps prevent wire tangling and bird-nesting. Aluminum MIG welders are available in a range of sizes and power levels to suit different welding needs. They are commonly used in automotive, aerospace, and marine industries, as well as for home repairs and DIY projects.

Frequently Asked Questions (FAQs)
1. What MIG welder can weld aluminum?
Pulse MIG welders, like the ones with arc pulsing and various functions such as start current, start-slope, end-current, and end-slope, are ideal for welding aluminum. These features help control heat, eliminate puddling, cratering, and spatter, resulting in high-quality aluminum welds.
2. Can you MIG weld aluminum without gas?
While gasless MIG welding is possible, it is generally not recommended for welding aluminum. The absence of shielding gas can lead to lower quality welds with a higher risk of porosity, cracking, and other defects.
3. Can a Hobart 140 weld aluminum?
The Hobart Handler 140 can weld aluminum with the appropriate shielding gas and wire. However, due to the longer length of the feed tube from the feed rollers to the tip, it may be prone to bird nesting at the feed roller. It is important to note that the Hobart 140 is not spool gun ready.
4. What happens if you MIG weld aluminum with steel wire?
Welding aluminum with steel wire is not recommended. Aluminum melts at a lower temperature than steel, so the aluminum will melt away before the steel even starts to glow. The metals won't fuse properly, resulting in messy, weak welds.
5. How hard is it to MIG weld aluminum?
MIG welding aluminum is indeed challenging, but it is not as difficult as some rumors suggest. It requires proper settings, technique, practice, and training. While there are many ways aluminum welding projects can go wrong, with the right knowledge and experience, it is possible to consistently achieve successful aluminum welds.
6. Why can't some welders weld aluminum?
Welding aluminum poses challenges due to its softness, sensitivity, and the presence of a tough oxidized layer. The material is highly susceptible to impurities while in its molten state, resulting in porous and weak welds. Additionally, aluminum and its alloys have a strong affinity for oxygen, making it difficult to achieve satisfactory welds without proper equipment and techniques.
7. Can you weld aluminum with a Lincoln 140 MIG welder?
The Lincoln PRO MIG™ 140 can be used for welding aluminum, as it offers gas-shielded MIG welding on thin gauge steel, stainless steel, and aluminum. It can also be set up for gasless flux-cored welding on thicker steel, providing flexibility for various welding applications.
