How to Choose the Best MIG Welder

Whether you’re a seasoned welder with years of experience or a novice looking to get their hands on a new MIG welder. Knowing what your goals are will help you identify the best MIG welder most suited for your needs. Some machines are able to power more electricity, creating a hotter arc, which allows for work on thicker metals than machines with lower power capabilities. Before making your purchase, decide which metals you will be predominantly working with.

While MIG is great for different types of metals, it is possible that another method of welding may suit your needs better, depending on the materials you will be working with. It’s also important to note where you will spend the majority of your time when welding. This will determine your power requirements, voltage, and the types of metals you can work with. By utilizing these tips, you will be able to analyze your needs and find the perfect unit while separating the good from the bad.

  1. Power Performance – 110V vs. 220V

Power input capabilities are a major factor to consider when choosing a MIG welding machine. A welder for small-scale projects at home or in the garage would run on a 110 volt powered through a standard household plug and do a great job. Because home welding projects are usually related to welding thin materials. If you are mainly weld metals no thicker than 1/8” inch, then a 110V MIG welder will do just fine. These 110 volt welders are great for portability but, in some ways, lack in power where higher voltage welders prevail.

Larger units are capable of powering thicker electrode wire, thus being able to weld thicker gauge metals. The voltage of the unit is altered to control the arc. Higher voltage allows for a hotter arc and can work with thicker materials. If you will be welding more thick metals as 1/2″ inch, then a larger 220V MIG welder would do a better job. If you intend to work with different types of metals, then it is wiser to choose a welder that allows a multi-voltage option. It allows you the opportunity to switch between power modes rendering more versatility.

Welding machines labeled 230V and 115V may get you confused, as commonly, there is only 110 or 220-volt power. However, welding machines can run with around a 10% voltage variance. This means that a 115V welder can run in a 110V outlet.

  1. Heat Capabilities – Amperage Range

MIG welders are classified by the output current amperage they produce at a given duty cycle. Basically, amperage is the heat it can produce, and the duty cycle is the length of time during a ten-minute time period. The power output amperage rating dictates the thickness and the materials you will be able to work with. Some approximate amperage ranges for MIG welding mild steel are:

  • 18 gauge: 70 ~ 100 amps
  • 1/8 inch:  120 ~ 200 amps
  • 3/16 inch: 140 ~ 205 amps
  • 1/4 inch: 140 ~ 225 amps
  • 1/2 inch: 250+ amps

Here is an example; for welding on a modern car with thin panels, a small MIG welder might be enough. For an older car with thicker panels, a 130A welder would be the minimum. While a 4×4 would require 150A or more.

Also, you ought to consider the minimum amperage rating. A welder rated with a minimum of 40 amps welds sheets up to 2 mm in thickness together. MIG welders for bonding thinner materials should have a 20 – 25 amp minimum rating, which would be more usable on 0.8 mm steel.

  1. Welding Time – The Duty Cycle

The duty cycle of a welder is expressed as a percentage measured at a given amperage. In layman’s terms, a duty cycle is measured strictly by the number of minutes you can weld continuously at a certain power rating without overheating the unit. A typical rating for a home 110V MIG welder is a 20% duty cycle at 90 amps. This means that with a power set of 90 amps; you can only weld continuously for two out of every ten minutes to avoid overworking the welder. The duty cycle is also inversely proportional to the welding output. When the welder is being used at lower outputs, the duty cycle is bound to increase.

If you are welding for personal use, it is possible that a unit with a lower duty cycle will suffice for your needs. If you’re a professional and will be utilizing the welder for paid work, it is imperative to find a welder which can satisfy your time requirements without the need to cool down continuously. Adversely, if time is not of the essence, a welder with a 30% duty cycle would be a sufficient choice. For thicker metals or bigger jobs, choose a MIG welder with a higher duty cycle.

  1. Multi-Function – MIG & Flux Core

The best MIG welder on the market support flux-cored functions. The MIG/flux-core welder is preferred if the work you want to do with the welder is diverse. Flux-cored welding advantages are:

  • Works well on dirty or rusty metals.
  • Provides deep penetration for welding thick sections.
  • Flux core wires are more suitable for outdoor work.
  • Eliminates the need for carrying a shielding gas bottle by using a self-shielded flux-cored electrode.

  1. Portability – Size & Weight

Depending on your working environment, you want to make sure your MIG welder will fit your needs in the majority of situations you will find yourself working in. If portability is an important feature for you, choose the best portable MIG welder, which weighs under 50 pounds, making it easy to move around different work sites.

The size of your welder will not necessarily define the power rating of the unit. Some small modern machines can deliver much higher power than bigger ones. You can also opt for wheels or a wheeled cart, which will allow you to mobilize your unit to fit the job needs.

  1. Customer Service – The Warranty

Something that should go without saying is to find a unit with reputable customer service and a useful warranty. Ensure having a warranty that you can rely on in the event that your unit breaks down is an important feature for caring about your investment. Most companies offer diverse warranties that can cover everything from broken parts, labor to repair the unit, or even replacing the unit if there are factory defects. Even the highest quality welders can experience mechanical and technical issues, and you’ll be kicking yourself if you’re caught without a warranty.

  1. Other Considerations

Some of the best features to look for in MIG welders are systems that allow for advanced auto-set control, not to mention fan cooling. Other features include;

Functionality Wire Feeders
  • Wire Feed Speed – It’s the speed at which the machine feeds the welding wire to the gun. Different materials require different feed speed in order to ensure an accurate welding process. Choose the best wire feed welder with a wide range of feed speed and ensure accommodating various materials. It’s a great feature to have.
  • Spool Gun Capability – In aluminum welding, the wire usually gets stuck in the torch as it gets fed from the wire feeder. Placing the wire inches out of the MIG torch through a spool gun eliminates wire plunges. Look for this feature if you intend on welding aluminum.
  • Built-In Contactor – Keeps the welder’s wire cold until the trigger of the torch is pressed. As a result, you don’t need to worry about accidental contact with the base metal when shifting positions.
  • Thermal Overload Protection – Most modern MIG units come equipped with thermal overload protection, which basically automatically cuts off the power if you exceed the machine’s duty cycle, to ensure you don’t overheat the power transformer. It also helps to prolong the machine’s life.

Lastly, the best MIG welder for the money that maintains the perfect balance between cost efficiency and your needs as a welder is important to understand. While it may not be an everyday thing where you spend hours in the garage working on a trailer, boat, car, or an art project, knowing your unit is reliable, adaptive, and functional in your life is crucial to a successful purchase.

Everything about MIG Welders

What is the process of MIG welding? Simply it’s a method that uses a wire electrode that is continuously fed through the MIG gun and using a ground clamp and a shielding gas, it forms a complete circuit. The voltage from the machine runs through the electrode wire to heat it and melt it into a weld pool on the base metal to bond metals together. In a MIG welder, the wire electrode is fed continuously and is considered a consumable. The shielding gas used is also a consumable. The shielding gas protects the weld pool from the harmful effects of the chemicals in the environment, which can weaken the weld.

Different combinations of wire electrodes and gases are used to weld different types of metal. Before beginning any project, ensure your electrode will be able to penetrate your metal, the correct gas or mixture is being used, and your power requirements are met.

The shielding gas can be provided with a gas tank connected to the same gun your welding wire is fed through so it would create a protective cloud around the weld. Or by using a flux-cored wire which releases a shielding gas when used through the gun or torch. Some MIG welders support the flux core option while others don’t.

MIG Welding History

This principle of welding was first developed in the 1800s. Over a century of modification later, the process known as Metal Inert Gas or MIG was developed. In 1948, the Battelle Memorial Institute developed this process of welding. The process involved a continuous electrode and sprayed the weld across the parent metal. An inert gas, typically argon, was required to shield the weld and act as a barrier from the atmosphere, which would corrode the new weld and weaken it.

It was originally thought that only inert gases were usable for MIG welding, which led to high costs for the gases. It was later discovered that carbon dioxide, which is not an inert gas, was usable and offered deeper penetration than pure argon gas. Since carbon dioxide was not a noble gas, the new name for the MIG welding process was changed to Gas Metal Arc Welding or GMAW. However, while more accurate in description, the name was not as popular and didn’t take hold. Other common names of this process are wire welding, Metal Active Gas or MAG, and Flux Cored Arc Welding or FCAW.

MIG Shielding Gases

In MIG welding, a shielding gas is used to protect the weld pool – which is the melted wire electrode – from the harmful effects of the atmosphere and the environment has on cooling beads. The shielding gas acts as a barrier to the molten weld pool from oxygen, nitrogen, and hydrogen contained in the air. These elements can compromise welds by causing holes within the beads, and excessive spatter, making the weld less stable.

The shielding gas is transported from a gas tank to the weld pool through the weld gun. The nozzle at the end of the gun can be changed out to different diameters, which controls the amount of shielding gas at the welding pool. The typical shielding gas used for MIG welders depends on two main factors. The type of metal you are working with and the thickness of the metal.

Most MIG welders use argon, carbon dioxide, and helium for the job. Sometimes mixtures of two gases are used to create different chemical properties for the weld. Mixing two gases also allowed for use on different types of metals.

Electrode Wire Types

For MIG welding, there are two main types of wire to choose from, flux-core and solid wires. The difference between the two lies in the flux coating found on the flux core wire. It’s a self-shielding wire that you can use without external shielding gas. It’s suitable for rusty or dirty metals and offers deeper penetration properties, thus suitable for thicker materials. However, this process creates slag and spatters that need extra cleaning time.

On the other hand, solid MIG wires create a better-looking weld with less spatter and less cleaning time. Solid wires are commonly used in home and industrial projects; they require a shielding gas to ensure the weld stays free from environmental contamination. They have a low penetration rate, thus suitable for thinner materials.

That said, a MIG welder can work with a good range of thicknesses, from 24 gauge, 18 gauge materials, and all the way up to 1/2 inch materials in a single pass.

How MIG Works?

home and garage use

Most MIG machines are used for home and recreational use. It is common to use a MIG welder on trailers, auto-body repairs, and art projects.

The majority of the metals can be handled by a MIG welder by utilizing shielding gas and high current. In addition, this type of welding works in many different positions and is one of the easier methods of arc welding to learn. To learn more about other welding processes, you can read our article comparing welding methods.

What Can MIG Weld?

A MIG welder works on a wide array of parent metals. This is partly due to the variations of shielding gases used, and the different wire electrodes you can select for each job. For most MIG welders, mild forms of steel are clear choices. However, you can also weld many other metal combinations. The most common metals welded with a MIG machine are:

  • Carbon steel
  • Stainless steel
  • Copper
  • Magnesium
  • Nickel
  • Aluminum (with a special feeder and spool gun since the aluminum wire is very soft)

Depending on how much voltage your MIG welder is running at, the weld can be set to one of the four transfer types; globular, short circuit, spray, or pulsed.

MIG Welders Uses

The great thing about MIG is that you can put a machine in your garage and weld up everything that comes your way. MIG welding is easy to learn, and you can do many things with it. MIG welding is most commonly used in vehicle fabrication to repair cars or motorbikes. It’s also used in construction where steel is the most commonly used metal. If you are looking for a MIG welding job in high production manufacturing, from computer components to auto parts, you will find that there are a variety of opportunities to choose from.

MIG Welding Types

MIG welding is a common form of arc welding in many households, as it works well with trailers, automobiles, and small farm equipment. It is a simple process to learn. There are four main classifications of MIG welding metal transfer types. Which are spray transfer, pulse spray transfer, globular transfer, and short circuit transfer. The difference between each metal transfer method simply pertains to the way in which the contact is made between the electrode wire and the parent metals.

MIG Welders Advantages

There are many advantages that a MIG welder has to offer. The fact that high-quality welds and beads are achieved in a simple and fast procedure is a great benefit.

high quality
  1. In MIG, high-quality welds can be produced much faster compared to stick or TIG welding. Welding wire is fed continuously, which allows for less downtime for replacing electrodes.
  2. In addition, using a continuously-fed wire minimizes the occurrence of defects on starts and stops.
  3. Only minor weld spatters produced. As a result, minimal post-weld clean-up.
  4. Allows for deep weld penetration, which gives the welder the ability to use a wide selection of filler metal compositions and diameters, to weld thick or thin materials.
  5. Very versatile and is used for a wide range of metal and non-ferrous metal, including aluminum, copper, mild steel, magnesium, nickel, iron, and many of their alloys.
  6. Not to mention, MIG welding is the most common industrial process to weld a broad variety of materials, parts, and structures.
  7. Requires less operator skill compared to other welding processes, for example, TIG welders.
  8. MIG welding can be accomplished in all positions.

MIG Welders Disadvantages

Although MIG welders have many advantages with the flexibility of materials and positions, they are confined by their inability to work with thicker metals.

  1. While it is possible to handle material thicker than ½ inch, it is generally easier to use a different form of welding for those materials.
  2. Burn-back is also a common issue when welding materials thinner than 1/16 inch.
  3. The process is challenging to apply in narrow or hard-to-reach places because the MIG welding gun is large and must be held close to the base metal (within 10 to 19 mm) to ensure that the weld pool is properly shielded.
  4. Relatively high levels of radiated heat which makes this process not ideal to use for vertical or overhead positions due to the possibility of excessive melt-through.
  5. The base metal must be clean and rust-free to achieve a clean weld.
  6. Lastly, the MIG welder uses consumables, which adds to the cost to acquire shielding gas, welding wires, tips, and nozzles.

After all, a MIG welder is a great versatile machine. Not to mention, it’s easy to master, you will find yourself spending most of your time with your new favorite toy. But, always remember safety first. Never forget to wear suitable protective welding gear such as a welding helmet and gloves. They come in light and durable materials, and you can get customized helmets as well. Not to mention to keep the fire extinguisher in your working area.
