What To Consider Before Buying A Mig Welder Under $500 Dollars?

The art of welding involves knowledge of many aspects, remember that you are merging two materials. In this section, we will briefly explain the factors to consider before buying the best MIG welder under 500.

Welding Power

The power and capacity of a MIG welder are essential to consider. Before starting to search, you should consider the size of the electrodes in the welding machine. For reference, a model with a rated power of 90 amps allows welding up to 2 millimeters metals. On the other side, 180 amps can weld 5 mm or above metals. Do not forget that the higher-level machines have a regulator, so you can adjust the power to what you need at any time. So, it is always appropriate to exceed the maximum capacity required if your budget allows it.

The torch

Depending on the type of torch, it generates or works with certain gases, being suitable for one or another use. For example, argon gas models are for aluminum, copper and nickel welds, while argon and CO2 models are suitable for carbon steel welds.

In any case, the torch and connector must comply with the universal connector that allows you to change the model of the torch easily. It does not represent a change in how much the equipment costs and guarantees long-term use. It is also advisable to consider the quality of the torch. If you plan to use it with very high intensities, it is convenient to look for MIG torch.

Control panel

The control panel equipped with knobs that allows to adjust the functions. The adjustments are necessary and must be done wisely to avoid errors in welding. Some models indicate the input and output voltage. Also, it has min/max wire speed, electrode diameter, welding percentage and more functions. With the parameters, you can weld metals safely and effectively.

Equipment protection

Typically, every decent MIG welder offers at least one safety mechanism. They have been integrated precisely to avoid abusive or more prolonged use than the welding machine can guarantee. On the other hand, the welder chosen must also include a protection system against surges, which prevents excess energy or electricity spikes from damaging the electronic system.  Without this, your appliance may catch fire.


Accessories do not directly affect the quality of the appliance and are highly appreciated, as they can save you hundreds of dollars when you buy the welding machine. Furthermore, this purchasing criterion can also serve as a decisive factor if you are not in doubt between two models of the same quality.

By following these factors, you can easily get a MIG welder under 500 that will ease your welding job.

Why Should You Buy A Mig Welder Under 500?

For several advantages, you should buy a MIG welder that will fulfil your demands and ease your welding task. Some of them are:

  1. MIG welders come with IGBT inverter that ensures quality and faster welding without losing any metal parts. You don’t need casting to weld metals with the welder. So, you will achieve clean welding where casting is not used.
  2. The welders work on gas and gas-less method. The gas method protects the ARC so you can use it for a long time. If you have a spool or MIG gun, you can easily weld aluminum materials without losing components.
  3. It has various usage, and both thick and thin metals can be welded with this method. While welding, it generates small weld spatters, which is less than regular welders. Also, the welders have a multi-functional system and voltage system.

For these advantages, you should have a MIG welder. So, you can buy the best one from our above reviewed MIG welders.

Frequently Asked Questions

Here, we have answered some frequently asked questions about MIG welder.

Can I weld aluminum with a MIG welder?

Yes, you can weld aluminum with MIG welder. Because, the welder comes with MIG gun or spool gun that allows to weld aluminum in 21 to 24 volts current.

Can you stick weld with a MIG welder?

MIG welders have wire feeder and STICK function that can stick weld perfectly. A 200 amp welder can ensure perfect stick welding.

Can mig welder weld stainless steel?

You can weld 304 grade and 316 grade stainless steel with the MIG welder at 110V and 220V power. Before welding, you should clean the surface with a fiber cloth.

Does mig welder use gas?

Mig welder works gas and gasless. The mostly used gas is Argon and Co2 combination that is known as shielding gas helps to weld metals, steel, aluminum etc.

Do gasless MIG welders work?

Gasless MIG welders are used in welding thin materials. In the gas-less mode, your welding ARC will not be protected and the electrode will not be appropriately consumed.
