Hobart Handler 140

best overall rating Hobart 500559 Handler 140 MIG Welder 115V

Key Specifications

  • 12-gauge Welding Capacity
  • 115V Input Voltage
  • 20% Duty Cycle @ 90A
  • Wire Feed Tracking

The Hobart Handler 140 is an incredibly popular welder for beginners due to its great welding capabilities on quarter-inch mild steel and 12-gauge aluminum.
Even though this machine can weld aluminum, it doesn’t come prewired to do so. You’ll need to readjust its drive system to prevent wire shaving and bird-nesting, and it doesn’t come with a spool gun for immediate aluminum-wire feeding.

What it does have is an infinite tracking dial to let you adjust the rate at which wire is feed through the gun’s nozzle.

Hobart has an informative video on the Hander 140 that you can watch here.


  • Built-in overload protection
  • Wide welding range with decent aluminum welding capacity
  • Easy setup for mild-steel welding
  • Compact and durable casing


  • Not spool gun ready

The most challenging part of using the Handler 140 on aluminum is setting it up. After doing so, simply plug it into a wall outlet and begin!

Lotos MIG175

best overall rating LOTOS MIG175 175A MIG Welder with Aluminum Spool Gun - Advanced Auto MIG Synergistic Setting, Voltage Fine Tuning, Gas MIG Welding & Gasless Flux Core MIG Welding - Brown, 240V

Key Specifications

  • 3/16-inch Welding Capacity
  • 115V Input Voltage
  • 20% Duty Cycle @ 70A
  • Comes with Spool Gun

The Lotos MIG175 has a max output of 175A, which allows it to penetrate mild steel sheets of up to a quarter-inch in thickness. When dealing with aluminum, simply plug in the spool gun, and watch as it effortlessly welds 3/16-inch sheets together in a switch, one-sweep motion.

The control board has two dials—one for voltage and the other for wire speed—which gives you a wide range of customizability for whatever thickness you’re working with. Consult the guide to see how to correctly set these dials based on your material’s thickness.

The 20% duty cycle can be a bit annoying, but built-in thermal indicators will alert you when you need to let the machine cool down.


  • Clean welding
  • Flexible controls
  • Ready to weld aluminum
  • Reasonable duty cycle


  • Could weld thicker material

The MIG175 is a great MIG welder that will be a handy addition to any home garage and metal workshop.


Before moving on, we’d like to address two very crucial points when looking at MIG welders for aluminum.

MIG Welding Aluminum Polarity

Welding non-ferrous metals like aluminum require DCEP (direct current electrode positive) or reverse polarity. This results in better penetration with less melt-off.

MIG welding with aluminum wire requires setting your machine to direct current electrode positive, also known as reverse polarity.

With reverse polarity, electrons travel from the MIG welder via the ground cable and back to the gun.

To set the MIG welder to reverse polarity, connect the clamp to the ground cable to the negative terminal and the spool gun to the positive terminal. You may have to open the machine to gain access to these poles.

Can you weld aluminum with 75 argon 25 CO2?

When MIG welding aluminum, you’ll want to avoid using CO2 as your shielding gas. CO2 is highly reactive to aluminum and will result in more spatter and a duller finish.

Ideally, you’ll want 100% argon as your shielding gas when MIG welding aluminum. It is an inert gas stabilizes the arc to keep your workspace and workpiece clean.

Check with the operator’s manual to see which shielding gas to use for MIG welding any type of metal.


1. Can I MIG weld aluminum without a spool gun?

It’s possible, as you’ll see a number of videos telling you how to configure your MIG welder’s drive system to work with soft aluminum wire. However, we don’t advise doing so, and neither do MIG welder manufacturers since 1) it can void the warranty, 2) spool guns are easy to set up and use, and 3) reconfiguring the drive system is a time-consuming task without any guarantees. Many of the models on our list come with a spool gun.

2. How difficult is it to MIG weld aluminum?

If we’re being honest, it’s a challenge that not many people are willing to undertake. Even experienced welders can have trouble welding aluminum due to its softness and complex welding techniques. However, with the right MIG welder for aluminum, you can overcome much of these difficulties with the right voltage and wire speed adjustments and specialized hardware.

3. Can I use a MIG welder for aluminum and steel?

Yes, you can. The polarity setting for welding both types of metals is the same (reverse), so you won’t need to switch the ground clamp between the positive and negative poles repeatedly. However, you will need to switch between the aluminum spool gun and the steel MIG torch, as well as swap install the correct consumable type. All of the products listed above are made for welding nearly all types of metals, including steel.

4. How do I weld two aluminum sheets with different thicknesses?

This is one of the challenges of MIG welding aluminum, but it’s possible to do. First, adjust the voltage and wire speed settings based on the manufacturer’s instructions to the thicker workpiece. Then, when pulling the trigger, focus most of the heat onto the thicker piece. The performance ratings mentioned for each MIG welder for aluminum is the maximum aluminum sheet thickness it can weld.


MIG welding aluminum can be tricky, but that’s just a part of the game. You can relieve much of the stresses involved with welding aluminum by choosing one of the best MIG welders for aluminum listed above. We’ve gone and tested over a dozen different MIG welders to create a meaningful list containing all of the necessary information you need.
