How many times have you wished you could weld? If you are like most people, probably never. However, sometimes this skill can come in handy. With the best MIG welder under $500, you can build a barbecue grill or make a gate for your garden. MIG stands for Metal Inert Gas.
If your budget is limited to $500, you can still get a good instrument with up to 140A power. We reviewed over 20 models and selected 5. Our top pick is the LOTOS MIG175. First, we considered maximum output as it determines the thickness of the metal that you can weld and its quality. Most of our models have 0.030-inch wires – perfect balance between quality and speed. The next is the duty cycle. Most MIG welders have a low duty cycle between 10-20%. This allows you only 1 or 2 minutes to weld within a period of 10 minutes.

What is a MIG welder?
A MIG welder is a wire-feed type of welder that is used to melt, shape, and combine various metals for strength and durability or furnishing purposes. It uses metal inert gas which is pumped through the welding cable from its metal tank.
The gas comes out of the welder’s cable nozzles and creates a protective cloud around the arc during welding. It can be used to efficiently weld several metal items at home, farm, or for industrial purposes.
What to expect from a MIG welder under $500?
There are features that most MIG welders under $500 have in common. Just because they are cheap doesn’t mean they are inefficient. They will get the job done, and you will save a few coins. Here’s what to expect from any MIG welder under $500:
Convenient power output
Most MIG welders under $500 do not consume a lot of power because they run on a low voltage ranging between 110v to 120v. This is because they are meant to be portable and highly convenient to use. You can plug them into your standard home power outlet.
Light duty cycles
Most MIG welders have a low duty cycle between 10-20%. This allows you only 1 or 2 minutes to weld within a period of 10 minutes. You just have to ensure you have a reliable power supply to make the most out of them.
Short cords
Short power cords of about 5 or 6 feet are common with MIG welders under $500. After all, long extension cords are not recommendable as they maximize voltage drop. However, if you want high mobility around your work, you can always go for the longer cords.
Welding capacity
With 120v input power, and about 90 to 120amps, you can weld mild steel as thick as 1/8 or 3/16 inches in one pass.
Features to consider when choosing a MIG welding machine
Before buying a MIG welding machine under $500, consider the following features:
Multifunction or MIG/Flux-Cored welders
You can buy a multi-function welder that can do both flux core and MIG welding. Since it allows you to smoothly transition the welding processes, you won’t have to buy various welding machines. It will save you time and money especially if you work various types of welding.
Input voltage
The input power, aka the voltage or amperage, is one of the most crucial things to consider before buying a MIG welder. The best input power is 110v to 140v because you can easily connect the welder to your standard home power outlet.
If you choose a higher power input, you will have to incur more costs and time to set up another power outlet.
Output power
The best recommendable output power is 140 amps for 115v. If you are looking to weld thicker materials, then you can go for a MIG welder with a higher output power like the LOTOS MIG175 reviewed above.
Size and weight
You have to be on the look for size, weight, and portability. If you want a welder for handling high volume jobs, then you must get a heavy-duty welder with a significant volume. Otherwise, if you only need one for light domestic projects at home, then you can settle for the compact and lightweight designs like the Lincoln Electric K2185-1 reviewed above.
Duty cycle
This is the amount of time you are allowed to weld before the machine goes to rest. It is measured in 10 minutes enhancement. The higher the duty cycle the more efficient the welder will be.
Wire diameter
The smaller diameter wires give the best welding results. They weld more stable at a lower current producing less arc force, which prevents a burn through. Bigger wire diameter welds are prone to causing burn through problems.
Welding capacity
A good MIG welder with an input power o 115v and output power of 140 amps should be able to weld mild steel as thick as 1/8 to 3/16 inches.
A MIG welder with a higher output and input power can weld from 3/8 to ½ inches of metal.
Spool gun
A spool gun plays a critical role in a MIG welder. Therefore, it is one of the key features that have to be considered before buying one. It is advisable to go for spool guns with the euro-connect because they are easy to use and are highly efficient.
Thermal protection
Thermal overload protection extends the lifespan of a MIG welder. It prevents the machine from overheating. It shuts down the engine automatically when it is overheated and restarts on its own after sufficient cooling without hampering your time and work.
Warranty
Manufacturers back up or affirm the quality of their products by offering a warranty. You should go for a MIG welder with a warranty as its quality is a sure bet and you can always get help if you encounter any trouble with it. You won’t have to spend a dime on repair and maintenance.
Wire-feed speed
This is crucial as well as it determines a welder’s speed and accuracy. Welders have varying wire-feed speeds, and you should choose one based on your preferences. It is advisable to go for a more extensive wire-feed speed range for optimum welding functionality especially if you intend to work on various metal items.
