MIG Welding Basics

MIG Welding Basics

If something around the house breaks, it has to be taken care of if you want your home to remain in top shape. Some things can be fixed with some pliers and a screwdriver, but you need a serious tool for more serious issues.

A welding machine, more precisely a MIG welder, has to be a part of your fixing arsenal. You can't go without one as it is almost guaranteed that it will resolve half of your problems that you happen to have.

YesWelder offers various MIG welding machines that suit different work demands and sit at different price points. That way we are trying to offer proper value for you, our customer.

You shouldn't buy a machine that is overly expensive and meant for heavy work if you will be using it for house repairs, DIY welding work, welding art or regular welding shop work. 

On the other hand, if you need a powerful machine for more serious work, you will need a reliable MIG welder that offers advanced features to complete your work without any sacrifice in quality.

Here at YesWelder, we are doing our best to offer our welders the best quality-price ratio. That way you don't have to spend a ton of money in order to get a quality machine that suits your needs.

Now let's learn a bit about MIG welding before we proceed to machines.

What Is MIG Welding

Metal Inert Gas welding, or MIG for short, is an arc welding process involving a continuous solid wire that serves as added material and electrode. The MIG wire is fed to the weld pool with the help of a welding gun. The joint is then created after the two base materials are melted together with the use of an electric arc. The weld gun also serves another purpose — providing the solid wire gas MIG shielding gas to the weld pool in order to protect it from atmospheric contamination while welding.

With the discovery of the electric arc in the 19th century, there came MIG welding too. Initially, carbon electrodes were used after a switch was made to metal rods. However, the official start of MIG welding is considered to be 1948, when the Batelle Memorial Institute created the process. Initially, it enabled short-circuiting transfer, supported all welding positions, and required lower heat levels for welding thinner materials.

Over the years, GMAW developed into one of the most popular welding methods for industrial use. You will mostly see it being used for welding sheet metal and, naturally, in the automotive industry. 

It is a process not suitable for outdoor welding because strong gusts of wind can disrupt the shielding gas. Nonetheless, it is perfect for indoor use and fixing things around the house. That is why having a MIG welder at hand is really valuable as it can help you fix your fence, a bike chain, or do some repairs on your car. YesWelder MIG welders are more than suitable for home use and can prove to be of great value, particularly for a DIY welder or a hobbyist.

Our machines have many useful features that will help in your work, like Synergic MIG control that automatically calculates and adjusts the wire feed speed and voltage based on the set amperage. You can always use the manual mode as well. Some of the other useful features are 2T/4T, hot start, setting the value of inductance, burn back time, multiple wire diameters, the ability to change the voltage on micro and macro levels, and many others. Moreover, they can also be used for stick and light TIG welding.

You may not need all of the features our welders provide.

In addition, we are in a vast number of cases better priced than other welding gear brands.

We love to provide our customers with as many features as we can. You never know when your work might need some fine-tuning adjustments on your machine.

Let's see this in practice now. These are our top MIG welders. Each of them is meant for different use cases and magnitudes of work.


YesWelder MIG-205DS-B Multi-Process MIG Aluminum Welder


YesWelder MIG-205DS-B Multi-Process MIG Aluminum Welder

This is one of our best-selling machines.

If you are a DIY welder or your welding shop doesn't do heavy welding, then you should consider our MIG-205DS MIG welder. Well, more like MIG, TIG, and Stick, but with the emphasis on the MIG process.

It has a maximum power output of 200A, which is more than enough for regular welding work. Furthermore, the 60% duty cycle will have you welding without taking big breaks.

We packed multiple features in it. It supports synergic control, handles welding wire of up to 0.9mm (0.035") for both the MIG wire and flux core gasless welding wire, it offers both 2T for simple work and 4T for prolonged and continuous forms of welding, allows for a quick switch among MIG, TIG and Stick welding processes and handles 2lb or 10lb wire rolls.

This is a portable welder. It is lightweight and works with 220V and 110V inputs. 

It comes with a MIG and Stick gear while the TIG torch is purchased separately. The TIG process works on DC only. Great for stainless steel, but not meant for working with aluminum.

Now let's see our more serious MIG machine meant for an even wider scope of work.

Our 250A MIG Pro is meant for working with steel, stainless steel, and it is also capable of MIG welding aluminum. 

Just like the MIG-205DS, this is also a 3in1 welder as it does MIG, TIG, and Stick welding. It has Synergic and manual MIG modes, dynamic arc control, and wide support for welding wire. It supports .023"/.030"/.035" solid/SS wire, .035"/.045" aluminum wire, and .023"/.030"/.035" flux core wire.

It outputs 250A of welding power because it is meant for more serious work. A welding shop that does thick steel or aluminum welding should consider the MIG 250 Pro or anyone who needs a high-power output.

A spool gun is purchased separately. This reduces the cost of the machine for those who are not immediately interested in aluminum welding. TIG torch is also sold separately because the main focus of this machine is advanced MIG welding.
