Best MIG Welder Reviews – Our Top Picks
After testing MIG welders from several brands, we think the Hobart 500559 Handler Wire Welder is the best MIG welder for most people. The Forney 309 is a worthy alternative, whereas the Lincoln PowerMIG 210 is where you should be aiming at if you want to settle for the absolute best in the business.
Metal Inert Gas (MIG) welding, also referred as Gas Metal Arc Welding (GMAW) was introduced during the period of Second World War as an effective method of joining thin gauge metal sheets and heavy steel tubes. The invention of this quick and easy welding technique aggravated the production of heavy-duty weapons.
MIG is one of the easiest processes of joining metal sheets, even a layman can learn it in just a few hours. MIG welders are particularly used by hobbyists for the convenient set-up of the tool. Others use TIG Welders & Plasma Cutters. To develop accurate, neat and smooth welds, possessing a good MIG welder is mandatory.
The top MIG welders in the market save both your time and energy as they allow thicker metals to be welded uniformly in one pass. With a suitable MIG welding device, not only you can obtain great welding speed, but you can also try your own bit of artistry on thinner materials. On the other hand, a defective welding machine can completely massacre all your efforts. Shopping for the best MIG welder isn’t as easy as you think.

What is MIG Welding?
In MIG or Metal Inert Gas welding, a spool of steel wire or electrode is continuously fed from the machine, first through a liner and then out of a contact tip in the gun.MIG also requires power to heat and melt the wire. The Inert gas (helium, argon) flows out of the gun and shields the weld puddle from the atmosphere which contains gases like hydrogen & oxygen for neat welds. The word Inert itself means the gas won’t blend with any other substance.
Most digitized MIG welders available today automatically regulate the electrical settings of the arc, and in that sense are vastly superior to butane torches that are gas powered. In case of the manual machines, you need to be careful about the torch positioning, welding direction, speed and amperage level. In a nutshell, MIG welding is all about melting the wire electrode in the arc to run a bead through feeding. MIG joints are widely chosen over stick welding as the former doesn’t allow any weld distortion by shielding the puddle against the atmosphere. Therefore, the joints are sturdier and more durable. MIG welding is performed upon a number of thin materials, aluminum, stainless and carbon steel and alloys.
Types of MIG Welding
In case of gasless MIG welders, a flux core wire creates a shield around the weld pool to prevent it from the oxygen in the air. Sometimes a self-shielding tubular flux-cored wire is also used which keeps the oxygen out by ending the need of gas from the atmosphere. When welding arc melts the wire and flux simultaneously, a gas shield is formed around the weld. So, technically, there’s no MIG welding without gas. Gasless MIG welding ensures deeper penetration and easy vertical and overhead positioning of the weld. A big downside of this kind of welding is the formation of slag and spatter between the passes, but they can be reduced with proper technique. For joining materials thinner than 1.2 m.m, you better skip this process.
Gas based MIG welding is performed by using carbon dioxide (CO2) or argon as a shielding gas and DC positive polarity. The choice of shielding gas makes a huge difference in the portability and quality of the weld. Gas MIG welders produce little spatter and provide a very stable arc. To know how a particular gas-based or gasless model performs in real life, you need to read MIG welder reviews carefully and note if most of its pros coincide with what you’re mainly looking for.
Advantages of MIG Welding
The reason why any seasoned welder would choose MIG welding over TIG or stick welding most of the time is that it can be applied on almost any material, be it thin aluminum, thick carbon steel or alloy. The self-shielding wire needed for the technique doesn’t cost a fortune. The simplicity of the process results in excellent control. The auto-feed wire makes producing cleaner weld pool an effortless, smooth affair.
You don’t have to change the rods or brush the weld constantly to remove the slag. It saves a lot of time which can be effectively utilized to boost productivity.
TIG welding takes a considerable amount of time to be grasped properly whereas MIG welding can be learnt and mastered over within just a few days of practice. Customers intending to use the welder essentially for home projects would find his “point and shoot” process much easier to deal with.
Ways to Choose the A Great MIG Welder
Input power rating
Basic MIG welders that could be adjusted to 115v-140v are suitable for small scale home projects, mainly used for joining thin sheets of iron and aluminum. Power requirements are way higher for industry-level projects in which very thick materials need to be welded as quickly as possible to meet the customer demand. For this, you need to go for obdurate, powerful welders like Hobart Handler 190. Keeping in mind the different kind of specimen you’ve to work on for a commercial farm, it’s best to play safe by choosing welder with multi-voltage option. It allows you adjust the power setting from 120v-230v whenever the situation demands. Some advanced models can automatically set the appropriate level of voltage you need for the specimen.
Wire size and material thickness
The size and type of wire weld can be neatly divided into two categories namely, ER70S-6 and ER70S-3. The former is commonly used to work on rusty, untidy surfaces when more deoxidizers are required whereas the second one is perfect for all kinds of welding purposes. Being aware of the type of material to be welded will help you determine the configurations, wire diameter speed, voltage settings and other features essential for the target task. Products offering auto-set option come very handy for professional welding. Once the Auto-set mode is on, all you have to do is to dial the thickness of the specimen and the machine will fine-tune itself accordingly.
MIG welders are primarily engineered for stress-free welding. Who wants to carry along a gigantic, heavy-weight welding machine that is not only painful to handle but also lends considerable foothold in your garage. Novice welders especially find it difficult to run the bead on the correct welding zone due to the excess weight of the tool. One thing you need to be careful about is not to prioritize the size. At the end of the end, it all boils down to the performance.
Duty cycle usually refers to the time limit within which the machine runs at a pre-set voltage and amp output without exceeding the temperature of the component parts. This output is inversely proportional to the welding output. It commonly measured by the performance in 10-minutes cycle. In a more elaborative form, if the duty cycle of a fabricator is 20% at a power input of 180A/240V, it implies that the unit will run for 2 minutes and need to be cooled down for 8 minutes before restart.
You go to the market with zero idea about what to purchase, a bunch of unscrupulous dealers will be more than happy to fool you for some extra income. Know your requirements well and you’ll successfully make the wisest investment of your hard earned money. Nevertheless, buying a good welding tool is one thing and using it efficiently is another. Lack of proper protection (for example, a good welding helmet) and right technique can actually put all your effort into soup.
In this article, I’ve tried my best to include and explain everything I’ve learnt about welding in my 20+ years’ career. Hopefully, it has helped to clear all the confusions you had about MIG and facts related to it. You can also take the opinions from the existing customers of a certain product before reaching any conclusion.
