What Is Mig Welder?
Being one of the power tools preferred by most welders today, MIG Welders, are efficient in all weld joints.
These welders use continually fed solid electrode that both shields gas from the outside and creates electrical power for electrode melting. That melting material will be deposited in the weld joint.
Coming to the MIG welder, it can automatically adjust the electrical arc characteristics. The controls require manual such as gun positioning, travel speed, and travel direction.
Once setting the right equipment, the power from the machine will provide the essential amperage for welding.
Advantages and Disadvantages of Mig Welding
What advantages and disadvantages will you meet if you choose to use a MIG welder? You want to know, don’t you? The answer is just below:
Fast welding speed – The welding time will reflect the difficulty level of weld joints as well as the quality from the using tool.
But, for MIG Welders, everything is the same. It is hard to find one that can beat MIG when mentioning the time because of the continuously-fed electrode. Ensure the wire electrode fed into the weld joints continuously.
Use in ease – The MIG torch can operate with one hand. Plus, a couple of aspects are automatic. Therefore, MIG welders are much easier to use than stick welding and TIG welding.
Long-pass welding – Frequently, people do not appreciate the MIG welders for small welding joints, but having said that, they are advantageous for long, complicated welding. You will save your time, not having to do with many passes.
Great penetration – The next benefit that you can have got with MIG is the ability to penetrate well.
The MIG welders can provide you with the smooth and energetic finish of welding. On top of that, this nice result can easily achieve when applying on an array of metals, aluminium, steel included.
Less starts and stops – Because of the constantly-fed MIG electrode, MIG Welding cuts down several times of stopping and starting throughout your job significantly. Additionally, there are adjustments and new electrodes that allow you to re-start the weld conveniently.
Elimination of stub loss – Unlike stick welding, MIG welding does not cause stub loss. You might utilize all electrodes without wasting any centimetre of welding.
Work with multiple metals and alloys – Initially, manufacturers have developed MIG to use for magnesium and aluminium alloys, but it has gradually improved better. Now, it can even work with mild steel, stainless steel, aluminium, and other filler materials.
Mess-free – Those who have ever experience stick welding often complain about the hassle of cleaning. Fortunately, MIG welding is less mess after each use.
Not including flux, you may not trap slag in the weld. That’s why MIG welding always creates high-quality welds. It is noticeable that the protective gas shield contributes to taking a large amount of weld spattering. It means that you are less maintenance.
Expensive – Investing a high-quality MIG welder lasting from years to years is beneficial. Some innovative models can even do both stick welding and TIG welding. And of course, they are very expensive, not mentioning the cost of repair and maintenance.
More maintenance – Because of the complex construction, the MIG welders require more maintenance, especially component-level repair.
Less portable – Although the now MIG welders are more portable than the traditional MIG options, they are pretty bulky, particularly when you use them in the tight corners. Nonetheless, most of the cases, we do not think so.
For example, the GYS 031876 MIG Welder in our list is quite compact and ideal for the narrow area. You can try considering.
Weird positions – For the tricky weld such as overhead or vertical welding, you cannot apply the normal technique because most MIG welders have a high heat input. If you want to do stick-welding, you must pick the right device.
Burn-through – As far as we know, MIG welding is not ideal for thin materials. It can make the less 5-mm workpiece of materials burn. Take care!
How to Choose the Best Mig Welder?
Next, we will guide you on how to select the best MIG welder UK. First, you need to consider:
The duty cycle, the running time of the welder before cooling down, is expressed as a ratio or the percentage. As an example, a welder having a 20% duty cycle at 90A will allow you to weld at 90A rating, going continuously for two minutes; this welder will cool down within eight minutes.
Nevertheless, a welder with a 20% duty cycle seems to be weak. It would be best to consider the machines at 60%.
The input power of welders is various, including 110V, 115V, 120V, 220V, or higher. Some models can offer both capacities.
For the standard household power outlets, you can consider the 110V welders, in case you do not want to replace a new outlet. And of course, this lower power will limit the ability to weld and output power.
On the contrary, the welders with higher input power, for example, 220V machines, will likely work on powerful welds on the thicker materials. And of course, you will need to install a 220V power outlet.
Size & Weight
You can ignore this consideration if you have a personal workshop and do not often move your welding machine. But, in case you must work at many different locations, you will certainly want to find a light welder in the weight.
The larger welders are more powerful. Inevitably, they are also heavier. Would you like to pick these welders? So, we recommend you to equip a cart with wheels for movement in ease.
For lighter jobs, you can consider a lighter machine like the STAHLWERK 200 ST IGBT Mig Welder in our list. It is under 7 kilograms. Super light!
Connecting to the handle on the torch, the spool gun, allows you to control the speed of movement of metal; it is especially useful when running on aluminium.
However, not all welders come with a spool gun. If you do not luckily choose the option, not including the spool gun, you can separately buy it. You ought to purchase one with the same brand to ensure compatibility.
You can go at your own speed during welding once you can adjust the speed. And you might achieve the desired temperature or heat with a welder that allows you to regulate the temperature.
Like that, your welding work will become more convenient. The best plan would be to invest in the machine coming with the adjustment settings. Keep in mind!
Brand & Warranty
A dependable brand will be a guarantee when shopping for anything. So, which maker is reliable?
Well, the different manufacturers give different support policy, but in most cases, Sealey, STAHLWERK, or Telwin are the most reliable names.
You should feel happy as our Mig welder reviews UK below are mostly from the brands mentioned.
How much is your paying capacity for a welder? You cannot pay for an expensive welder while your budget is narrow. Instead of choosing the highest-cost welder, you ought to pick the suitable one.
Our welder list has a range of prices you can consider. The machines under £200 are ideal for a small money pocket, and the larger spend will be the units at about £1000.

For those who are searching a MIG welder for their small home workshop, the Sealey SUPERMIG140 can be one of the suitable choices. Don’t have to spend too much while the quality is sufficient.
Because many people mistake this machine used for both gas welding and gasless one, we want to claim right from the start that it is for gas welding only.
The maximum performance can reach up to 140 Amps. Though this number cannot compare to two machines at the same price range above, handling short projects is easy. You can weld about 0.6mm steel.
If need, you can use CO2/Argon mix, Argon, or CO2 for welding.
For CO2, it will become active and help to improve cleaning action. Adding a small amount of Argon (about 5-25%) will help CO2 stabilize the welding arc. Then, with a CO2/Argon mix, it makes the weld pool more fluid and minimizes weld spatter.
Nonetheless, the Sealey SUPERMIG140 does not feature a cooling fan. Can we use it for lasting welding?
Don’t worry! Sealey does not use a fan to cool the welder, but it has a Forced Air Cooling System. The cooling speed is faster than a fan. You like it yet!
- Very easy to use
- Handy size
- Well built
- Perfect for DIY
- Capable of the task
- Difficult with larger projects
