MIG welding has been gaining popularity over the last years. As it is often the case, it is the first choice for beginners because it is relatively easy to learn and use. However, there are some questions beginner MIG welders are too afraid to ask. In this blog post, we will answer some of the most common questions that beginners have about MIG welding. Without further ado:
Questions beginner MIG welders are too afraid to ask
Are Harbor Freight MIG Welders Any Good?
Harbor Freight has a big brand name in the world of MIG welders. Be it professional welders or ones that homeowners prefer, be it low volt or high duty cycle. The best thing about Harbon Freight welders is that their high portability and flexibility.
Not only this, but this brand makes welders for every price range. Whether you’re finding an excellent economy MIG welder or an expensive one, they have it.
What Causes Holes in MIG Welding?
The main reason for the cause of pinholes during MIG welding is the lack of shielding gas in the cylinder. When there is an uneven flow of gas during MIG welding, this causes the creation of Pinholes.
Apart from Gas, If you are welding outdoors in much moisture, the water molecules will get trapped in the weld. Such moisture causes the formation of pinholes in the weld.
What is the Difference Between MIG and TIG Welding?
The only difference that MIG has with TIG is the way the arc is used in welding. In the process of TIG, long rods are used to connect the two metals.
While MIG welding, a feed wire is used instead of Long rods. This feed wire moves through the gun, creating a spark that causes the metal to melt.
What is MIG Welding Used for
Metal Inert Gas welding, also known as MIG, is a process of welding that is usually used for large or thick material. Through the feed wire, a spark is created to weld.
This process is much faster and results in a lower cost of welding than processes like FCAW and TIG. Furthermore, compared to TIG and FCAW, this process is also pretty easy to learn and get used to.
Why is MIG Welding So Popular?
The reason for the popularity of MIG welding is due to its simplicity in the process. This feature encourages a lot of hobbyists and DIY creators to weld without needing much skill.
MIG welding is also popular because of its high work rate and speed compared to many other processes. Even more, beginners find welding a lot easier by the process of MIG. So they can practice and learn better on this process since MIG is more straightforward and user-friendly.
What Is The Best Inexpensive MIG Welder?
Mostly, beginners, are people new to welding prefer machines that aren’t too costly. Several options in the market fulfill this requirement. This article has provided you with just the right amount of picks that maintain hardware quality and performance.
The products recommended above are not just ones that are among the best budget MIG welders. There are picks from 110V to even above 220V, which means they’re meant for almost every type of buyer.

Are Gasless MIG Welders Any Good?
Yes, glassless MIG welders are excellent compared to gas-powered MIG welders. They are more efficient and also provide a higher productivity rate. As no shielding gas is used in the process, the only disadvantage is that you cannot use gasless welders in outdoor projects.
Furthermore, Gasless MIG welders have better penetration ability as compared to gas-powered welders. That makes them suitable for thicker metals. But I do believe that both gasless and gas-powered MIG welding processes are good in their ways.
Which welding is best for Beginners?
MIG welding is the best type for any beginner to learn. As they are a semi-automatic or automatic process, beginners find it easy to understand compared to other methods. What makes it less complex is shielding gas that protects from oxidation, making it easy to weld.
Through MIG welding, you usually get clean and better results which no other welding process can give. Furthermore, the slag that is produced during welding is also much easier to clean in MIG welding. This makes MIG welding a perfect method to practice welding.
What Is The Best MIG Welder For The Money?
We believe that the Hobart Handler 210 is one of the most budget MIG welders in the market. It has such a low price. Furthermore, the value it brings out of the money spent is enormous.
It is lightweight and easy to carry. It has enough power that makes it capable of welding quality metal. Beginners can get the hang of it in less amount of time.

What is the hardest/most difficult metal to weld?
Amongst all the metals, Aluminum is the most rigid metal to weld. This is because of the different properties it has as compared to other metals. For instance, it is soft, and for it to be welded properly, you need some specific tools.
A lot of caution is also crucial while welding Aluminum because it is susceptible. Being a highly reactive metal means that it can be hazardous because of its spontaneous reaction properties.
What Is The Hardest Type Of Welding To Learn?
TIG (inert tungsten gas) is the most complex type of welding to learn. It requires a lot of skill to be weld through TIG as both your hands and legs are utilized, making it pretty troublesome at points.
Furthermore, TIG is a slow and detailed process, and so it needs a lot of concentration and time to finish welding properly.
What type of TIG welder is best for Aluminum?
Aluminum is a highly conductive and very fragile material. Due to these distinguishing features a TIG welder should have certain features to weld aluminum. Most importantly the TIG welder should have an option to work on AC power supply. Tungsten rod gets really hot if you use a DC power supply that could damage the weld. Pulse weld could be a great add on if a welder with this feature falls into your budget. Alternating Current is the perfect option also because of change in polarity. Aluminum oxides are broken up on the surface of the metal with the help of polarity flips.
What Duty Cycle is ample for general welding?
General welding could have so many definitions. Duty cycle of a welder shows how much time you can run it without overheating. For instance a welder with a 20% duty cycle will run for 2 minutes and then take 8 minutes to cool down. If you can’t afford to take breaks then TIG welders with 60-80% duty cycles are available out there. Make a wise decision in this aspect. Either you will cherish or regret because of the duty cycles.
