What Is MIG (Metal Inert Gas) Welding?

MIG welding is actually metal inert gas welding. When performing MIG welding the process that fuses the metal together is done using a continuous feed of metal wire, or filler. This filling agent makes it possible for you to weld together thicker pieces of metal than you could join if you were using a TIG welder.

How It Differs From Other Welding Methods?

Both the TIG welder, or tungsten inert gas welding and the metal inert gas welding or MIG welding are types of arc welding. The methods of performing the welds are very similar, but each type of welding has a specific time when it is better to use.

MIG welding is more forgiving than the TIG welding is, because the MIG welds are made using a continuous feed of metal wire, and when you do TIG welding there is not always a wire or filler agent used.

So when you are TIG welding you will need for your welds and connections to be more accurate. This makes the metal inert gas welding more suitable for new welders, and novices.

MIG welding is better suited to create a strong hold when you are welding thicker items together. The metal wire that is used as filler helps you to create a secure bond between thicker items.

MIG welding and flux core welding are very similar. Both of these techniques involve a continuous feed of the metal wire and they can both be used on thicker materials than TIG welding can. The main difference between a MIG technique and a flux core technique is the shield of the arc during the process.

You also have to consider the metal you are trying to weld when you choose between the two methods. If the metal is more resistant then you want to use the TIG method. Resistant metal gets hotter faster and it is perfect for TIG applications.

IN FCAW or flux core welding the arc is shielded from wind and exposure to exterior elements by the flux core, so the welder can work outdoors without their operation being interfered with by Mother Nature. The MIG process does not shield the arc as well so gusts of wind can interfere with the job you are doing.

You also need to remember that whenever you are using a filler material like you use when MIG welds are made or flux core welds are made, then you have an increased chance of splatters. The splatters do not weaken your welds, but they do not look as smooth and neat as welds with no splatters. If you need a smooth line then choose the TIG method.


How To Pick The Best MIG Welders For The Money


Choosing the top MIG welder for your purposes will require you to know what types of materials you will work with the most. You also need to consider other features of the machines so that you can get one that uses the power source you have readily available, and is easy for you to maneuver, transport and such.

The following things should be considered when you are purchasing a MIG welder.

The Voltage Of The Machine

You can get a MIG welder that runs on 110v and you can get one that runs on 220v, so it is normal to wonder if one machine is a better choice, or if there is a real difference in the machines.

If you get a MIG welder that is powered by your normal 110v household outlets the amperage the machine can produce will be limited. The amperage produced by a welder plugged into a 110v outlet is perfect for welding materials that are 1/8” thick or less.

This means that fancy and craft workers will be able to use the 110v welding machine, but people who want enough power to weld on thicker steel will want a 220v machine.

Spool Gun

If you plan to be welding aluminum then you need to get a MIG welder that has a spool gun, or has an optional spool gun. If you never intend to weld aluminum, buy the machine that has no spool gun capabilities because you will save a ton of money, but for aluminum welds you need that spool gun.

Low Amperage Machines

Low amperage machines cost less than the higher amperage machines. Not everyone needs to have a high amperage machine. If you are a hobby welder then you will likely never need to weld with anything that requires gas, the flux core welds will be great for your purposes.

Duty Cycles

The duty cycle of a welding machine refers to the minutes that you can weld at a specific amperage during a ten minute cycle without causing the welding machine to overheat. 

If you weld short pieces of material, or in short spurts, then a low duty cycle will suit your needs. If you work for longer periods of time and need to make longer welds at higher amperages then you need to buy a machine with a higher duty cycle capability.

Size and Weight

Size and weight of your machine are also indications of the overall power of the machine. If you will be welding thin materials or using the machine for craft projects then you can probably do everything you want to do with one of those small machines that weigh less than forty pounds.

If you have some heavy duty welding to do, or you work a lot on your farm equipment, mower decks, automobile bodies, trailer hitches, or large projects, then you need to look for one of the larger and heavier machines.

Choosing the best machine is all dependent on the materials you will weld, and how often you will weld.


MIG Welders for Newbie: What to Consider


Welding is becoming a popular profession around the USA as welders can start with a good money from the very beginning. However, you don’t need to get a 3-4 years educational degree to be a welder.

The MIG welders use continuous wire feed to create the welds so that means that starter welders will make fewer mistakes that are highly visible and it means that even if the beginner misjudges the thickness they can still create a strong and durable weld.

New welder professionals should take the following things into consideration when they are buying a welding machine. 

You are not always going to be a beginner so buy a machine that you can use now, and one that will have the capabilities you are going to need later. If you know you are going to want to weld aluminum one day, then make sure the welder you buy will accept the spool gun.

Your safety equipment, like your welding hood and gloves are vital items that you cannot scrimp on. Buy yourself the best hood and gloves that you can get. Your safety is worth more than the few bucks you might save buying cheaper items.

Buy an MIG welder that can be used with gas or with flux core. There are times when the flux core is the perfect way to weld, but there are going to be times when you need hotter temps, and the productivity of the gas. Buy a machine that gives you the option and you will always be prepared.

Voltage controls and being able to control the speed at which the wire is fed to you during your work is important.

Buy a machine that has a set up guide. When you first begin you will need the advice of the experts on what temperatures you need to be welding different metals at. Make sure the machine you are buying is one that has a guide to walk you through all changes you need to make before you begin welding a different material.

Important: Before starting a welding job, you should be well educated on welding. Don’t miss our guide on welding school costs if you are aimed to be a certified welder. It takes a few months or a year to become an expert welder. So, focus on your study first and then start your dream career. 


Convert MIG Welder To A Plasma Cutter 


You will need to take a brass plumbing valve and connect it to a ¼” diameter copper tube and put a brass cap on the other end.

You need to drill a hole in the cap and then tap the threads so that you can fit a brass carburetor jet into the hole to convert it to a plasma cutter.

Attach the tube to the handle of your arc welder.

Use a carbon electrode with a sharp end, so it looks like a sharpened pencil, not a welding stick.

You will need to flex the nozzle so it is pointing towards your electrode.

Put a quick release compressor hose coupling on the plumbing valve and then connect the compressor hose to this coupling.

Crank your welder amperage up to over 25 amps and under 50 amps. This should give you enough oxidation and a hot enough arc to cut through metal that is less than 1” thick.


3 Steps to Choosing Your First Welder

Buying your first welder can be a big decision. Let’s see how putting the considerations above into practice can help you with it. Keep in mind that it may take more steps—or fewer—for you to select the right machine for your needs.

Step 1: Match Your Skills to a Welding Process

MIG, Stick, and TIG are the most common welding processes, and each one requires a different type of machine setup.1

Deciding which process you plan on learning first can help you determine the type of welder you need.

MIG Welding (Beginner)

MIG welders are among the best type for beginners, as they’re designed with a wire welding electrode on a spool that is fed at a pre-selected speed through a welding gun. As a semi-automatic or automatic process, gas metal arc welding (GMAW or MIG), is the easiest to learn.

MIG Welding Benefits
  • Simple to learn
  • High welding speeds
  • Cleaner welds2

Stick Welding (Intermediate)

Compared to other welding processes, it may take longer to get the hang of shielded metal arc welding, or stick welding.

The name of this process can give you a clue as to what it entails: a flux-covered metal electrode is used to carry the electric current from the machine to the metal workpiece. As it burns, the flux emits a gas to shield the weld pool, which later settles to form a protective slag over the work. Meanwhile, the metal electrode melts into the joint, strengthening it.3

Stick Welding Benefits
  • Works on a range of metals
  • Indoor and outdoor use in wind
  • Effective on rusty or painted materials1

TIG Welding (Advanced)1

Gas tungsten arc (TIG) welding requires advanced welding skills. One reason for this is that TIG welding is a manual process in which you hold the torch with one hand and feed the metal filler rod into the weld puddle with the other.4

TIG Welding Benefits
  • Precision welds
  • Foot control to adjust heat input
  • Higher-quality, better-looking weld beads

Step 2: Align Welding Process with Project

In addition to skill level, you’ll also want to think about what types of projects you’ll be working on. Each welding process (and its specific welder) has unique applications.

MIG Welding

  • Automotive and trailer repair
  • Lawn and garden equipment repair
  • General fabrication and repair
  • Metal fabrication
  • Art and sculpting5

Stick Welding

  • Farm and ranch equipment repair
  • Construction (structural welding)5
  • Assembly of temporary structures
  • Jewelry making6

TIG Welding

  • Automotive assembly.
  • Shipbuilding
  • Aircraft welding
  • NASA welding6

Step 3: Determine which Welder Fits with Your Budget

Once you’ve figured out which type of machine you need, it’s time to shop around for the model that best fits your budget.

Be sure to factor in the costs of all the other welding equipment you’ll need when putting together a budget, such as the costs of the welding helmet, jacket, welding gloves and other essentials.

It’s a big decision. Put some thought into it and take your time.

Advantages of MIG Welding

MIG welding is the most popular type of welding process. Some advantages of this welding process include:

  • MIG welding is fast. MIG welders save time for users because the user does not have to change rods often. Furthermore, it saves time as users do not have to clean slag formed from welding constantly. It produces a fine weld.
  • MIG welding is cheap. Getting a high-quality MIG welder does not cost as much as getting other welders. With less than $600, a welder can get high-quality equipment for the process. You might have to spend money on shielding gas and MIG wire, though, but even with this added expense, it is still cheaper than other welding processes.

Furthermore, consumables spent on MIG welding are less than other processes.

  • MIG welding is easy to master. Compared with other welding processes, it is easy to learn. Others might have a steeper learning curve, but MIG welding takes a short time to learn.
  • MIG welding is versatile. With this process, a welder can weld various types of metals. You can weld copper, mild steel, aluminum, iron, and different alloys. Furthermore, you can weld different thicknesses as long as the amperage and configuration are right.

Disadvantages of MIG Welding

  • While the welder might be lightweight, the cylinders that house the shielding gas can be heavy and cumbersome to carry around.
  • The material to be welded has to be cleaned which can take some time
  • Not meant to be done outdoors: MIG welding is not meant to be done outdoors because it is sensitive to wind. The shielding gas can be blown away during the process, which will affect the quality of the weld.

Conclusion

As a beginner, choosing the perfect welder may be a challenge. There are a lot of specifications and uses to understand and compare, which can make it difficult to make an informed decision.

As a novice welder, you may want to stick to certain product types to ensure optimal value and use. Although TIG welding allows maximum versatility, it is not an easy technique for beginners. MIG techniques are much easier, but then you are limited in terms of material types.

Beginners may be better off opting for multi-process welders, as they provide a broader scope in terms of metal types and overall use.
