Top MIG Welder You Can Find in 2020 — Reviews, Ratings & Buying Guide

What is a Metal Inert Gas Welder?

Metal Inert Gas welding is an arc-welding process which uses a solid continuous wire electrode that’s heated and fed into a weld pool with the help of a welding gun. The two base materials are melted and fused together to form a joint. The gun that feeds the shielding gas alongside the electrode helps in protecting the weld pool from any airborne contaminants of any kind.

The Metal Inert Gas welding was created and patented in the United States, back in 1949 and was initiated by welding aluminum. The weld pool and the arc that was formed using the bare wire electrode was protected with a layer of helium gas that was readily available at that time. From around 1952, the process gained popularity in the UK as argon was used as the shielding gas to weld aluminum and for creating carbon steels with the help of CO2.

The argon-CO2 mixtures are also known as MAG or Metal Active Gas processes and these are an alternative to the MMA, which offer high rates of deposition along with high productivity.

How do you set up the metal inert gas welder?

The metal inert gas welder works with pulsed metal transfer and short-circuiting for low current operation while the spray metal transfer is used with the help of high welding currents. In the “dip” transfer method, the molten metal that’s formed on the wire tip is transferred by dipping the wire into the weld pool. This helps in achieving a low voltage that varies between 17 V to 22V. There must be care taken when setting up the inductance and voltage when related to the wire feed speed, which is essential in minimizing the occurrence of spatter as well. The inductance is used to also control surge in the current, which occurs when the wire is dipped into the weld pool.

For the spray transfer or droplet, there is a much higher voltage necessary which ensures the wire doesn’t make contact or short-circuits itself with the weld pool. The molten metal found at the tip of the wire is transferred to the weld pool with a spray of small droplets. There is also a minimum current level threshold and going below this means the droplets won’t be forcibly projected across the entire arc. If the open arc technique is attempted below the current level’s threshold, then the forces wouldn’t be sufficient to prevent the large droplets from forming right at the tip of the wire. These droplets also transfer in a non-linear and erratic manner across the arc under normal gravitational forces, so take care of the same.

The pulsed mode allows you to stabilize the open arc at a much lower current level, which is below the required threshold level, to avoid the occurrence of spatter and short-circuiting. The metal transfer is then achieved by applying various pulses of current, with each pulse having enough force to detach from a droplet. The pulse MIG refers to a type of controller which enables the source of power to be tuned for the wire diameter and the composition, with the pulse frequency set according to the wire feed speed.

What can you weld with a metal inert gas welder?

The MIG method is commonly used in industry sectors and also accounts for up to 50% of the weld metal deposited. The MIG method has an advantage in terms of deposition rates, flexibility, and suitability for mechanization as well. It should also be noted that the MIG is different as it offers a “squirting” metal and a high degree of skill is demanded for the MIG welder.

What is Flux core Wiring and can my Welder use It?

The Flux-cored arc welding method is an automatic or semi-automatic method of arc welding. It requires a continuously fed tubular electrode consumable that contains a constant voltage and flux or less commonly, a current welding power supply. The externally supplied shielding gas is used sometimes, but the flux itself is relied on to generate protection from the atmosphere, producing liquid slag and gaseous protection.

Your welder can use this technique as there won’t be a need for a welding gas. There is also lesser cleaning of the metal required. The benefits from a metallurgical perspective include the weld metal being protected from external factors until the slag is finally chopped away, with the porosity chances also being low.

MIG Welding shielding gas basics –

Most MIG welding applications need a variety of shielding gas choices and you’ll also need to evaluate the welding goals for you to choose the correct one for the specific application. The gas cost, the finished weld properties, preparation, base material, weld transfer process, productivity goals, post-weld clean up are all factors that need to be taken into account when you’re planning on selecting a shielding gas.

The most commonly used shielding gases include Oxygen, CO2, Helium and Argon. They all provide unique benefits and also come with their drawbacks, depending on the application.

Choosing the right gas –

Oxygen is used in rations of 9% or less in order to improve the weld pool fluidity, arc stability, penetration in low alloy, mild carbon, and stainless steel. Helium, like argon, is used for non-ferrous metals and also used with stainless steel. Helium also works with thick metals and is used in 25-75% ratio Helium to 75-25% Argon

Getting the Gas to the Weld Pool –

If the equipment isn’t getting the gas to the weld, then trying to get the right shielding gas gets wasted. The MIG gun consumables which consist of contact tip, diffuser, and nozzle play a big role in ensuring the weld pool is also protected from the air atmosphere.

What to Look For When Buying a MIG Welder

There are a number of parameters you need to pay attention to before you pick a MIG welder that is ideally suited for your use. The best MIG welder for you is the one that gets the job done on all of your welding requirements without being underpowered. It should also make working with it easy and reliable. Here is what you need to look for in the best MIG welders:

Input Power

Although most welders operate at 110 to 140 volts, a number of models coming out these days run on 220 volts. If your shop’s outlets are designed for input voltages of around 110v, you have nothing to worry about. On the other hand, getting a 220v model would mean some extra electrical work to get the higher input socket.

Duty Cycle

The duty cycle is an important factor that tells you how long you can run your MIG welder before giving it a cool-down break. It is based on the percentage of 10-minute increments. For example, If it says it has a 35% duty cycle when operating at 135 Amps, it means you can weld with it continuously for 3 minutes and 30 seconds before allowing it to cool for 6 minutes and 30 seconds. The best MIG welder will have a high duty cycle at high Amps.

Weight

The lower the weight, the easier it is to haul the welder around the site. The average weight of most welders is about 50 pounds.

Thermal Overload Protection

The thermal overload protection is a handy safety feature that kicks in and shuts down the machine when you overstep it. All the best mig welder models will have this feature and it is something worth shelling out extra for if you tend to lose track of time when focused on welding.

What Metals can I Weld?

If your work mostly revolves around mild steel, stainless steel, and Aluminum then a mig welder will suffice. Some welders can also handle a few alloys and iron.

The thickness of Metals/ Material Thickness

Mig welders are ideal for use in sheet metal, light to heavy frame welding, welding of boat, car, and bicycle components. They can handle steel from a thickness of 24 gauge (0.5 – 0.6 mm) to ½ inch (12.7 mm) thick steel plates.

Safety Features

An overload protection feature and a ‘fan-on-demand’ can go a long way in saving your equipment from permanent damage in case of overheating.

Spool Gun

Spools gun gives you a greater degree of control over the welding speed and the deposited material. They are especially useful when welding aluminum. Even if your machine doesn’t come with one, you can buy this as an accessory from the manufacturer.

Does Your Job Require MIG or is Flux-Core Enough?

Flux-cored welding offers more flexibility to the process especially when you are working at a site where portability is important. It’s also helpful when working outside in the elements. It does have a limitation as it cannot handle aluminum.

Powering Up Your New MIG Welder

Figure out your welder setting based on what metal and thickness you are about to weld. Have the fume extractor read over the work area where you are about to start. The machine’s grounding clamp needs to touch a grounded metal so you won’t get shocked. Check the adjusting screw of the gas cylinder and ensure it is loose. Open the top valve and set it to the right pressure so your flow gauge reads 10 to 15 CFH.

Frequently Asked Questions (F.A.Q)

What is the best MIG welder for a beginner?

The Forney Easy Weld 140 FC-I is one of the best MIG welders there is on the market suitable for beginners.

Is Arc Welding stronger than MIG?

The strength of a weld depends on various factors such as the tensile strength of the deposited metal, surface preparation, type of joints, and more. Arc welding can do better when there’s a lack of surface preparation and thicker material. However, getting the best out of them depends on selecting the best method for the task at hand and the skill of the welder.

How thick can a MIG welder weld?

MIG welders can start with metals as thin as 0.5mm and the best mig welder can do up to 12.7mm.

What amp welder will I need?

That depends on the thickness of the sheet of metal. A small welder running on 115v can weld a ¼ “thick steel at 140 amps. A 220v welder can generate 200 amps and weld up to ½” thick steel.

Are gasless MIG welders good?

The gasless mig welders are more portable and suitable for use when working under the elements. They are also cheaper than regular mig welders.

What is a good MIG welder for home use?

The Millermatic 211 is a good choice for home use as it is light at just 38 pounds and gives a 40% duty cycle at 150 amps.

What is the best all-round welder?

The Lincoln Electric Power MIG 210 Mp K3964-1 is one of the best over-all performers out there on the market.

What is the best single-phase MIG welder?

The Hobart Handler 140 MIG Welder is great for hobbyists and beginners.
