Sealey MIGHTYMIG100

Weld As Long As You Need

Sealey is one of the biggest manufacturers of tools and accessories in the UK, offering approximately 8000 items including tools for home, repair shops, agricultural facilities, as well as cleaning. In this variety, we found a gasless MIG welder MIGHTYMIG 100.

The machine is able to weld metal sheets of a different thickness thanks to a toggle that allows setting the amperage to the minimum and maximum. The output range will be 55A and 100A, respectively.

Of course, with these things, sizes matters too. Measuring 32.6 x 52.2 x 38 centimetres, the unit is not necessarily large, although we wouldn't call it compact too. The welder weighs 14.5 kilograms, so you should be able to transport this device relatively easily.

At the same time, the company's Euro Torch incorporates fast-action connection that enables easy maintenance and decent mobility. Meanwhile, the heatproof cables and the contoured handle let you manoeuvre this unit with comfort and finesse.

We should say that the welding time at the minimum power won't be over 6 minutes. Yet, this welder will run for about 2 minutes at 90A and that's great considering its moderate price. In addition, you'll be able to manage the joint by varying the speed of the wire feed, just turn the relevant control knob to the desired setting.

Review of Sealey MIGHTYMIG100 Professional Mig Welder

Forced Air Cooling

By the way, the welder is compatible with a flux-cored wire up to 0.9 mm, and the weight of the spool should be 0.9 kg. Like most welding tools, it features overheating protection and the orange light will notify you when the welder gets overheated after long use.

Apart from that, the forced air cooling system will chill the welder's internal parts. Directing air over the transformer, the system slows down the heating process, increasing the unit's duty cycle and making sure you're able to use this MIG welder as long as necessary.

The welder has a non-live torch for your convenience that will increase the accuracy of welding and provide safety.

We're not saying that this welder doesn't have its downsides though. For the most part, we're fine with its foibles but cannot gloss over the fact that the unit produces a lot of fumes, so we wouldn't necessarily call this device especially eco-friendly.

All things considered, we believe that this welding tool will be an excellent choice for high-load projects to deliver wide weld joints thanks to a pretty thick allowable wire. Also, its 90-amp output is solid relative to the price.

Display4top MIG 100

6 Uninterrupted Minutes

The people behind Display4top market this particular model as a professional MIG welder and we can't say that they make a poor case in that regard. For one, its duty cycle is definitely up there.

With its 48A rated output, the model is able to work for 6 minutes straight before overheating. It comes equipped with a variable wire speed control trigger, so you'll be able to efficiently work with different metals. There are two power settings and an ampere knob, further making the versatility case.

These things matter. Having said that, they do not matter as much as the unit's construction though. When the construction is not up to par, these specs/characteristics are irrelevant because there's nothing you can do to make them last.

Fortunately, you don't have to worry about longevity here. In fact, this machine is among the most durable MIG welders we've looked at. First and foremost, the heavy-duty stainless steel body is as tough and rugged as they come. The body's basically immune against rust and corrosion. It is able to protect the internal components from the elements. You won't have to worry about the unit's housing warping and bending with time.

Meanwhile, the durable red paint will make sure that the housing doesn't start chipping and fading with time, keeping the appearance presentable, whilst the stainless steel body keeps the machine performing at its best.

Flux-Cored Wire

Besides the unit's construction, there's also the forced air cooling system keeps the temperature at a nice, practical level. On top of that, the welder incorporates a thermal overload protection system that will be able to pick up the former's slack in case it fails to do its job.

Sure, it isn't a perfect product. Some might find the handle a little impractical, especially as far as transportation is concerned. The welding mask and the wire brush that come with the welder aren't nearly as professional as the device itself, so you'll probably have to invest in slightly more professional gear, provided you have more than just light DIY projects in mind.

On the bright side, the flux-cored wire makes sure to automatically release the inert gases whilst welding, protecting the welded part from oxidation.

Long story short, what we have here is a really solid MIG welder. Though the whole package is nothing to write home about, the model's performance, durability, and safety mechanisms make for an effective, efficient, and reliable assistant.

Dirty Pro Tools Mig 130

Work Longer, Pay Less

Out of a huge product range of the Dirty Pro Tools, we have found a top-grade MIG welder that turned out to be so good that we have decided that we couldn't avoid adding this product to the shortlist.

Despite the name though, this machine's not that dirty. Sure, its gasless operation is pretty dirty considering that these gasless units rarely can tussle with gas-based machines. We're getting ahead of ourselves though.

For starters, let's review the unit's profile. As you can probably tell, the machine looks stern and streamlined. The valve and the switches are pretty large and easily accessible, so you won't be wasting any time trying to find these things and wondering how to manage the welder's settings.

The unit's as compact as these welders get. Measuring 48.5 x 41 x 24 centimetres and 14 kilograms, you'll have no issues bringing this machine with you. The huge handle will let you transport and move this unit around with ease. The handle's grippy yet, at the same time, fairly comfortable.

Review of Dirty Pro Tools Mig 130 Welder

Dirty Enough

Setting these measurements aside though, the machine's specs and performance are more than good enough to receive some highlight. First things first, this unit will let you weld metals that feature medium thickness. The machine's output ranges from 50А to 60А, meaning that you'll have no troubles welding 2-millimetre thick metals.

At the same time, the surprisingly powerful converter of this welder allows working for about 6 minutes at 50А. In other words, you'll be able to weld thin pieces for a good while, whilst the fan will make sure to keep this machine as cool as necessary to keep things nice and safe.

Sure, the welder might still get pretty hot from time to time. However, when this MIG welder overheats, the red light will start flashing, telling you to stop welding and pause for some time. By the way, you can pick either of 4 available amperage settings and adjust the wire feeding speed for reliable and straight welds.

We were also pleasantly surprised by the package that includes a face shield, a clipping hammer, a brush, and a spool of welding wire, so you can start welding right after unpacking the unit.

To put everything above somewhat differently, this Dirty Pro Tools welder is one of the most affordable models for people seeking a mid-power machine to weld fine metal sheets. The controls are simple and accessible enough to make this unit suitable for experienced customers and DIY enthusiasts alike. The machine's also as safe as they get.

Sealey SUPERMIG275

Massive but Transportable

The Sealey SUPERMIG275 makes pretty much no compromises. This machine is massive. In fact, that's basically where the product's biggest flaw lies.

Measuring 40 x 80 x 30 centimetres and 78 kilograms, this unit isn't even remotely approaching "compact". It is anything but compact and lightweight. As you would imagine, you might face some storage and transportation challenges.

Having said that, these challenges shouldn't prove too, well, challenging because the unit incorporates manoeuvrable castors and this massive handle that will let you move this MIG welder around without any issues. The handle's rubber-coated, so you won't have to worry about blisters and the castor wheels are large and sturdy, meaning that you won't have to keep the surface in mind when trolleying this unit around.

At the same time, the extra-large case will make sure the circuitry and the unit's internal components remain safe and secure despite the conditions/elements.

Review of Sealey SUPERMIG275 Professional MIG Welder

Euro Torch

Setting the welder's profile aside, let's pivot towards its performance. First things first, the unit's 270-amp maximum performance is no joke, even without taking the product's affordable price into account. You'll be able to continuously weld car panels despite how thick the materials are. In fact, you'll even have no issues welding stainless steel and aluminium, which is seldom the case with these budget welders.

The machine comes fitted with this spot-welding timer that will let you consistently weld without burning holes through various materials. That's not the product's biggest selling point though. As far as we're concerned, the biggest selling point is the Binzel® non-live Euro torch since this thing works wonders reducing accidental arcing. At the same time, the torch is comfortable to hold and wield, keeping the weld bead steady and letting you have as much control as possible over the welding process.

We've seen the company's forced air cooling system before. In a nutshell, the system directs air over the transformer, slowing down the heating process and increasing the machine's duty cycle. As you would imagine, the system also makes this welder last as long as possible.

To sum this all up, the Sealey SUPERMIG275 is as professional as these machines come. You'll be able to weld with accuracy and consistency despite the conditions/materials. In addition to the machine, you receive this industrial twin-gauge gas regulator, 0.8-mm contact tip, and a gas cup.

Röhr MIG-250MI

IGBT Monotubes

The Röhr MIG-250MI has to be the most well-thought-out and complete MIG welder within its price range. There are so many little details here separating this product from its competition that you can start anywhere.

For one, there's the latest IGBT tech. Incorporating this bipolar transistor that uses an insulated gate electrode, the semi-conducting device gives you the field-effect transistors' easy control and the bipolar transistors' fast-switching and high breakdown voltage. At the same time, limiting electrical continuity, this tech makes the unit pretty much immune from short circuits.

Using ARC Force, the machine makes sure that the current is increased automatically when the arc gets shorter. Meanwhile, the Hot Start works wonders automatically boosting the tension at the arc's ignition of the arc, facilitating electrical arc ignition.

Of course, the product is about its high-end components as much as it is about these technologies/features. Incorporating inverters, this MIG welder increases its efficiency by 30 percent, drastically reducing the power required to weld and producing the most consistent power supply, making sure that the welding arc remains stable and secure.

Apart from that, the aforementioned IGBT monotubes increase the machine's efficiency too when you compare these tubes' performance to standard MOS tubing.

MIG and MAG Weld

Pivoting towards smaller features, the anti-stick function sticks out the most (yes, that was intentional). When the electrode manages to stick to the materials, the function makes sure to switch off the welding current, preventing the electrode from overheating.

At the same time, the stepless wire feed system lets you focus the attention on the weld, ensuring flexible welding.

The "3-in-1" in the title up there refers to the unit's ability to MIG and MAG weld. MIG welding lets you weld magnesium, copper, and just about every other non-ferrous material and their alloys. On the flip side, MAG welding enables you to work with steel, structural steel, and its alloys.

Because the machine's able to do both (as well as ARC welding), the Vari-gas valve has been installed to let you regulate the gas flow.

Last but not least, though the welder's great, the accessories that come supplied with this machine are brilliant too, including an earth clamp, welding mask, cleaning brush, 3 collects, 2 nozzles, and this sizable storage bag that lets you store and transport these accessories.

In short, the Röhr MIG-250MI will let you weld low-carbon steel, stainless steel, and its many alloys. The machine will enable you to weld without worrying about short circuits and overheating. You'll have no troubles welding vehicle parts, doing fabrication, house maintenance, and carrying out many more unconventional tasks.

What Is a MIG Welder?

If you are a real handyman, you might have done some metal works, not to mention joining and installation. Yet, if you have some experience and you are ready to pick up the gauntlet of repairing metal gates or welding a pedal to a bicycle, a MIG welder is what you need!

A few welding methods are known such as MMA, TIG, MIG, and MAG. We will look through MIG welders in our review. A MIG welder uses a streaming inert gas that acts as a shield and expels air contaminants from a weld zone. If no gas is used, the seam is porous and infirm. We will review household MIG welders plugged to a power outlet. Such welders can fuse stainless steel sheets and weld cracks and holes on cars, etc.

We have examined 5 best MIG welders to help you buy an appropriate model for your welding needs.

Also, we advise paying attention to disk sanders and that will help you get the surface prepared before welding, as well as angle grinders for cutting metalware.

What Features to Compare

Type

MIG welders are divided into transformer and inverter models. Briefly, transformer machines feature only mechanical parts that can adjust the output voltage “sequentially” while the unit is off. The output voltage is not stabilised and may decrease under load. Still, a simple design is the main benefit of transformer welders that facilitate their maintenance. Also, they are often cheaper. Inverter MIG welders are fitted with electronics that allow a smooth voltage adjustment, so it isn't susceptible to drops and does not fall under load. Of course, power is the main feature of any electric tool. As for MIG welders, their power depends on the maximum amperage, more usually, the output range. This range determines the unit's field of application. Powerful models can be used on small construction sites or in repair shops, while less powerful models are usually used for private needs. For example, the welders of up to 200A are great for home use; the 300A models are suitable for small repair shops, and if you need a high output and continuous work, consider welders over 300A.

Performance

The MIG welder performance depends on several parameters. The duty cycle is among them. It means the percentage of a 10-minute period the welder can work until it gets overheated. For example, “90A / 20%” means that a welder can work for 2 minutes at 90A before an 8-minute cooldown, i.e. 20% of 10 minutes. Now, about the material. We should note that the maximum thickness of a material a welder can handle depends on its amperage and welding wire thickness. Lastly, consider the thickness of the joint a welder can make in a single run. Household models can weld metal sheets from 18-gauge to 1/4” thick at the output of 70A - 180A, respectively.

Extras and Conveniences

Gasless welding, which is also called “Gasless” or “No-Gas” welding, is the main convenience of contemporary MIG welders. That means they can make welds either with or without gas. It is possible thanks to the use of a special tubular wire filled with a flux and metal powder called a flux-cored wire. In a nutshell, when a flux-cored wire is used, its components generate a shielding gas under a high temperature that is essential for a high-quality joint. The thermal overload protection is also a useful feature that will switch the unit off automatically if the temperature reaches a certain level. Surely, a MIG welder is not something you will carry every minute. Yet, if a machine is lightweight and fitted with wheels, using it will be much more pleasurable. Finally, pay attention to the kit each tool comes with. Some models include a welding shield, coil, attachment for flux-cored welding, hammer, or brush. So, take these features into account when buying a welder.
