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 55А and 100А, respectively. 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 90А 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. 

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 an overheating protection, and the orange light will notify you when the welder gets overheated after a long use. Apart from that, the forced air cooling system will chill the welder's internal parts. The welder has a non-live torch for your convenience that will increase the accuracy of welding and provide safety.

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.

Is This MIG Welder Really So Lightweight?

It's another gasless MIG welder manufactured by Wolf. The Wolf MIG 130 yields the output range of 50А - 120А that enables welding metalware up to 6mm thick. It is possible thanks to 2 toggles that provide a varying output power for a specific part. In addition, you can set one of 10 wire feed speeds, so that welding could be fully under your control. As for the welder unit, it will let you control all processes and stability of operation thanks to handy indicator lights. Once the tool has been used for too long and requires a break from work, a corresponding light will flash up warning you to make a pause. However, owing to the built-in cooler, the runtime of the welder is still pretty long and should be enough for most jobs. Being small and lightweight like it is, the Wolf 130 welder's output makes only 13A which won't be sufficient for tough welding tasks unless you've been planning to replace the wiring in your place anyway. The shipping package isn't wide too and includes only a spool of a 0.8mm wire.

So, this MIG welder will be appropriate for handling metalware of medium thickness as its minimum output is 50А.


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 to add it to this shortlist. It is the tool for welding metalware of medium thickness with the output range from 50А to 60А, best for sheets up to 2 mm thick. In addition, a pretty powerful converter of this welder allows working for about 6 minutes at 50А. So, you'll be able to weld thin pieces for a good while, and the fan will provide a decent cooling of the tool. 

However, when the MIG welder overheats, the red light will flash telling you to stop welding and make a pause. 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 pleased 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.

So, this Dirty Pro Tools welder is one of the most affordable models for people seeking a mid-power machine to weld fine metal sheets.

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.

More importantly, the model is as durable as they come. 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.

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.


A Complete Kit

The Autojack MIG100 has its flaws but none of them make a convincing enough case to prevent the model's appearance on our list. It's a good product for a lot of different reasons. First, it incorporates 4 stage power settings. Add to that the variable wire speed control and you have yourself a truly versatile tool.

The internal turbo fan cooling system here is represented by an oversized blower that circulates air at a higher speed. The air vents on the sides of the model are also larger than average, a design solution that improves heat dissipation.

Having said that, what we like most about this MIG welder is probably just how suitable it is for people with different levels of expertise, from beginners and hobbyists to experienced welders and professionals.

Part of it is its input power. Part of it is also the output/duty cycle. But, most importantly, it is just how complete of a kit you get. Aside from the tool itself, you receive a mask, clipping hammer, wire brush, and wire. In other words, everything you need to get started straight from the box. The particularly long 2.5-metre Torch cable and the 1.5-metre Earth clamp cable certainly don't hurt either.

Sure, as we've said earlier, the model has its flaws. For one, the white housing, though quite sleek, is easily soiled due to the nature of the trade.

But, in spite of any of its flaws, the Autojack MIG100 is a reliable tool, with characteristics that do not trail behind the model's more expensive competition, with solid features, practical components, and one of the most complete kits in its price range.

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 sandblasts 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.
