MIG or Metal Inert Gas is a welding process that allows you to join two base metals using an electrode and a welding rod or wire. The electrode or MIG wire melts as heat is applied to form an adhesive. This liquid that flow is what joins the metals.
The welding gun produces an inert gas that shields the joint from contaminants in the atmosphere. Most of these wire feed models do not need welding rods making the metal joining process faster. The whole operation is simple enough for you to use despite your low skills.
A high-end MIG welder model allows you to work on metals like aluminum, stainless steel, and nickel irrespective of the thickness. It produces smooth joints at a faster rate. It can operate in both semi-auto and full-auto modes. For non-ferrous metals such as aluminum or nickel, pure argon is used for joining.
You’ll need a wire drive system, welding gun, inert gas tank, and power source for your MIG welding. The wire drive system draws the electrode out from the spool for it to pass through the gun. This process generates heat thus, the need for a cooling system. So, if you’re using a water-cooled gun, you’ll need a water source.
Whether you prefer a TIG or a MIG welder, choosing such a device may not be as easy as you think. Don’t worry, this buying guide has everything you need for a safe buy.
Things to consider when buying
Now that you have a little idea about this machine, it is important to know how to make your choice. So, knowing the following features and aspects will help you make the right decision.
1. Welding processes
MIG welders can either come with flux-cored or multi-function welding.
Flux-Cored Welding – This welding process allows you to perform the metal joining operation without an extra gas cylinder. The only disadvantage is the residue that you’ll remove with hand.
Multi-function Welding – This multi process function allows you to switch between two welding processes at any time. It is very useful when you’re working on a project that involves different welding techniques. It also saves time and cost because the two processes are in one machine.
2. Input voltage
Each of the top models operates at an input voltage level which might be different from your power outlet. But, you can choose to get models with dual voltages. So, what are these voltage range? These include:
110 -120 Volt
This is the most fitting machine for home use since you can connect the plug to your power outlet. But, its output power is low which makes it only suitable for thin or soft metals. Thus, you’ll need to increase the power to join thicker metals.
The 220 Volt model is perfect for joining thicker metals. But, you’ll need to install a 220 Volt power outlet when using it in your home. It is ideal for outdoor projects, especially where you cannot access the 110 Volt outlet.
AC power source is most common for these tools. However, there are DC options for which the price is on the higher side.
3. Duty cycle
The efficiency of the machine is a product of its duty cycle. It determines the length of time you’ll use the machine per session of the weld. The duty cycle is given as a percentage. So, how do you calculate the duty cycle of a MIG welder?
A MIG welder with a duty cycle of 70 percent will operate for 7 minutes before it overheats. Then, it’ll take another 3 minutes for it to cool. And a 40 percent duty cycle will run for 4 minutes and then rest for the next 6 minutes.
If the output power of your machine is high, your duty cycle will be shorter. This means, the time it’ll take the machine to cool is proportional to the quantity of heat it generates. Yet, good models come with efficient fans and vents that help reduce its cooling time.
4. Thermal overload protection
Some models come with overheat or thermal overload protection. This feature stops the machine once you exceed the duty cycle. Thus, saving it from further damages or injuries to the user.
5. Material thickness
As our field-testing suggests, some of the high-end 110v models did not have the power to penetrate thicker metals. They could join thin sheet metals comfortably. So, you’ll need to invest in a more powerful machine if your metal piece is very thick.
Yet, the thickness of the material will determine the thickness of the wire that’ll be used for the weld. So, if the material is thin, then you’ll use a small wire. But if the material is thick, the wire will be large. Also, the wire and the metal should be of the same material. For example, to join a stainless steel material, the electrode will be of stainless steel.
6. Output power
The size and type of the material you’re to join will determine your output power. Most of the top models come with instructions that allow you to set the right output power for the weld.
Here is an example of the chart that shows the thickness of the metal and the output power.
Metal Thickness in mm
Output Power in Amps
7. Size & transportability
Another important factor you’ll consider when choosing your machine is its size, weight, and ability to carry. If you’ll be using it only in the workshop, then the weight is not a problem. But, if you’ll be moving it to a different location, then you should buy a model that is small and lightweight with a suitcase design for portability.
You know that the heavier the welder, the harder it is to transport. The most portable tool weighs only about 20 pounds while the heavy models weigh from 200 pounds up. Most of these portable machines use an inverter which in turn, lowers their weight. Lighter models are easy to handle, so, vertical and horizontal both types of welding can be operated.
8. Spool gun
Most welders do not allow you to attach a spool gun which is very necessary when working aluminum materials. You need to look out for this feature before buying your machine. Also, try to buy a spool gun that comes with the quick release feature.
9. Shielding gas
The application of shielding gas, mostly CO2 (Carbon Dioxide), protects the liquid welded metal from contacting surrounding Hydrogen, Oxygen, Nitrogen and other hyperactive gases that would otherwise quickly react to the freshly applied metal and degrade its quality. For this reason, MIG gun consumables throw the shielding gas on the freshly molten metal to keep it corrosion free
10. Repair & maintenance
Make sure you buy from a reliable manufacturer who provides a set of complete papers with detailed user manual and maintenance tips. It's not just this metal joiner, whenever someone is buying a gadget, the warranty policy must be understood beforehand. In case you face trouble with your machine within the warranty period, this will save some bucks. In the later section of this review, we'll be giving you some maintenance tips, you're advised not to miss it.
11. Brand & warranty
One of the things that will reduce the cost of maintenance is the warranty. If your welding machine has warranty coverage, then you’ll not spend much to fix it. Some brands offer at least 5 years’ warranty along with customer support services.
Ensure that you buy from a manufacturer with a warranty. Try to compare the ratings and reviews by other users before buying.
MIG welders could be as low as $200 to as high as $1400 (multi-process welders). Your budget will determine the quality of the unit you might use.
Mig welding safety tips
MIG Welding is an aspect of engineering that needs much safety and care. Failure to adhere to its safety rules may result in accidents, injuries, or death. To protect yourself and your machine, you’ll need to remember these safety tips.
Always wear a welding helmet that comes with a shade. The lens quality should be either 10 or 11. This will help to protect your eyes from UV radiation which results in arc eye.
Wear leather hand gloves to protect your hands from burns and electric shock. You can buy gloves with reflective coatings to limit the effect of heat from heavy metals.
Weld in an area with good ventilation. This will reduce the volume of hazardous fumes that you’ll inhale when working. It’s also important to wear a mask if you’ll be welding for long hours.
Protect your feet by wearing leather shoes or boot. Sometimes, a hot plate might fall and burns if your foot is bare. Avoid shoes with mesh on top or those of plastic body. The plastic parts can melt and stick to your feet.
Remove saw dust, papers, and plastics from your work area. This is because molten hot materials that fly off during welding can cause a fire on dropping on these materials. Also, don’t keep any flammable liquid near your welding place.
Don’t expose yourself to the vapor from galvanized steels. The zinc oxide coating on this metal is cancerous and can damage your organs.
Mig welder maintenance tips
No matter you own a TIG welder or a MIG welder, maintaining your machine will help prolong its life and save you from unnecessary spending. Below are some of the maintenance tips for this kind of welding.
Try to cover your welder with a thick clothe when it’s not in use.
Choose a perfect time for the cleaning of your welder and adhere to it. This will help to remove dirt that may cover the moving parts of the machine. Note that dust deposits could affect the overall functioning of the tool.
Ensure that you connect the power cord to the standard outlet. Also, the fuse of the power outlet should match with the machine.
Clean the drive rolls and set it correctly. Try to adjust the tension of the drive roll to balance it. Replace the drive rolls once they’re worn out.
To prevent the buildup of pressure in the drive roll, clean the liner by blowing it with the air nozzle. This will clear the debris from both the feeder and torch’s ends.
Clean the gun nozzle periodically. It receives the greatest heat during the weld making the tip to need replacement more often. Cleaning the spatter will prevent dirt from blocking the smooth flow of gas.
Check the gas lines and remove any visible obstruction. Ensure that you plug in the gas nozzle rightly. This will prevent the gas from leaking.
Check the feeder connection regularly. If the connection is loose, tighten it. If it’s too tight, loosen it.
Always avoid undercutting by using the correct welding technique.
Try to pay attention to the conditions of the handle and trigger. Clean the two to prevent the accumulation of dust.
Be observant and respond on time when you sense a buildup of heat.
Replace any worn-out cable on time.
Check your ground to be sure of its connection. A bad ground can produce poor quality results. It can cause the malfunctioning of the feed wires or damage to the tip.
Before you order for a MIG welder, do a little research beforehand to know the features that’ll meet your needs. This buying guide contains every piece of information you’ll need to buy the right model. Since we have so many equally good models on this list, it’ll be tough to recommend one. So, if you’re on a low budget you can opt for the Super Deal Pro. It is inexpensive but can handle light welding projects.
Also, if you’re a beginner or hobbyist welder then we recommend the Forney Easy FC-I. It is light, portable and easy to handle. You can take it to almost anywhere with ease. Now, you can go ahead and buy any model from our list of best MIG welders.
You can also visit the following metalworking tools that we reviewed right here on Drillly:
Ans: Here is a list of metal combinations that cannot be fusion welded together: stainless steel and aluminum, copper and aluminum, steel and carbon, steel and titanium. and titanium and steel. The metallurgical properties of these materials don’t allow them to be welded together under any circumstances.
Q: Is Arc Welding stronger than MIG?
Ans: The stick welder has a much better metal penetration rate than a MIG welder. You have probably noticed that just keeping the arc on will require additional amperage input for the welding machine.
Q: What's the hardest metal to weld?
Ans: The hardest material would be stainless steel materials due to its high chromium density. That makes it behave differently than other types of steels.
