Super Deal PRO commercial MIG130best for welding thin metals

This is among the many light-duty welding machines, and is good for the lighter metals that you cannot weld using a stick welder, such as sheet metal. This is because of its automatic feed system, which helps you get the job done easily.

Specs

  • Lightweight and powerful – built from high quality PVC material
  • Makes use of convenient flux – self release metal-inert gas and cored wiring
  • User-friendly interface to help you handle the harder jobs with convenience and ease
  • Has 4 control buttons for 1/2, MAX/MIN. also has 10 adjustments for wire feed speed
  • Thermal overload protection features with a cooling fan to guard against overheating
  • Metal tip at the end of the weld gun

The welder can handle metal thickness of 16-gauge to 3/8 inches easily, including aluminum of the same thickness, which makes it quite versatile. If you are a beginner, you will find this fairly useful because it will permit you to practice your welding with different thicknesses and materials.

There are also a wide variety of accessories that come with it – which include a wire brush, a spool of flux welding wire, extra electrodes, tips and fuses, as well as a 2.5m torch. However, do not always rely on the wire that is included in the package, because the thinness will cause it to have its own issues with the automated mechanism of the machine. The weight of the machine is incredibly light, only weighing 38 lbs., and the design is compact enough to allow you to store it anywhere.

On the other hand, the wave form control technology it uses can reduce its spatter while increasing the depth of fusion and its performance. The slag buildup is also significantly reduced thanks to the welding gun’s copper tip, which is also easy to replace when it wears down.

The major problem we have with it is the build – instead of stainless steel, it is made from PVC. This brings to light questions about its durability. In addition, the limitation of only using 110V as its input severely limits its output and power, as well as the thickness of metals it can handle, which make it not be a top pick on this list.

Pros

  • Good quality of welds due to the use of wave form technology
  • Good flexibility on the wires and wire feed speeds
  • The copper tips at the end of the gun reduce messy slags
  • Good weld speed control choices and wire feed

Cons

  • Poor output of power
  • Less durable construction

Verdict

While this welder has plenty of advantages that come with it, the build quality is a major disappointment. That said, it is good enough to handle minor welding jobs around the house, but avoid relying on it for a heavy-duty job – or else, it runs the risk of breaking down.

  • 4 voltage settings and indoor chart to help in selection
  • Can handle welding thicknesses of 24-gauge to 1/8 inches (mainly steel)
  • Input voltage of 115V
  • Continuous adjustments of wire feeding speeds

This welder is capable of handling both flux core and MIG welding, and is best in home repair projects as well as welding light-gauge mild steel. It is quite simple to use, but the major disadvantage is the pricing – since it comes at a budget friendly price, it lacks some features that are a preserve of the more expensive welders such as infinite control of wire feed speeds or voltage settings.

The maximum amperage it has is 88A, which makes it one of the lowest rated in terms of output – so it will not work for heavy welding tasks. You will have four voltage settings you can select from, and the highest setting will allow you to weld thicker metals. The good news is that there is a good chart that shows you the settings to choose, depending on the thickness of the metals. It also runs on a low input voltage that allows you to use it in your home.

Another major plus is the lightweight and compact design, allowing you to transport it easily. To help you pick it up, the top of the machine has a solid handle.

Pros

  • Affordable for budget users
  • Durable build and has solid mechanisms
  • Portable and lightweight
  • Self-shielded flux core welding
  • It is flexible in wire size use

Cons

  • It can only handle mild steel
  • Limited control panel adjustments

Thanks to its build and specifications, it can handle a wide array of projects. It uses a voltage of 110V, and has a 72.5-inch long power cord. The maximum output to expect is at 15% when it is running on 105A of power. However, the amperage of 105A means that you cannot use it to fuse very thick metals or alloys.

The standout feature though would have to be the adjustment settings, which allow you to change things up according to the specific project you are working on. It also has a strong plastic handle and steel frame, which ensures it can handle various conditions without the risk of breaking down quickly.

Another advantage is its portability and versatility. Because it only weighs 35 lbs., moving it around is very easy and you will likely not require extra help to do so. The top handle also enables easier carrying, and the smaller dimensions ensure it does not take up too much space in your workshop.

Note that the package includes a welding mask that measures 9.5 inches x 7.87 inches. While this is a great choice if you are an occasional welder, it will not be enough if you are planning to us it in industrial settings or for professional projects.

Pros

  • The cord is long enough to allow you to use it multiple settings
  • Handle is plastic and has non-electrification properties
  • Heat dissipation mechanism to avoid accidental burns
  • Durable frame
  • Very affordable

Cons

  • Breakers sometimes trip, which can be frustrating
  • Welding power is minimal

LOTOS MIG140 Flux core & Aluminum welderbest for DIY use

If you are a person that enjoys spending time by doing DIY workshop projects and light repair work around the house, you will find the LOTOS MIG140 welder to be right up your alley.

Specs

  • Aluminum wire feeder that gives a more improved welding experience
  • You can adjust the wire feed speeds through the 2 digital displays
  • Semi-auto and manual switching (2T/4T) for easier control
  • Output of 140A, input voltage of 110/120V
  • You can use it for stainless steel, aluminum (using a spool gun), mild steel, and other metals
  • Limited warranty of 1 year, and 30-day money back guarantee
  • Wire ranges of 0.025 to 0.03 inches

While the manual (4T) and semi-automatic (2T) switching of the wire feeding mechanism is quite useful to help you get some extra control in the welding process, it does not have as high of a quality weld as you would find in the Hobart Handler 140 that we reviewed earlier.

The input and output is roughly the same as you would expect in a versatile welder, allowing you to use it in your home for lighter projects, and the duty cycle of 20% at 90A is quite sufficient for most uses. The only problem here is the shell, which is fragile and larger, and the leads are not that long either which can be disappointing.

The gas line setup and the regulator are also available for use if you want to use it to perform some MIG welding tasks or weld other metals as well.

Pros

  • Large amperage output of 25 to 140
  • Portable and lightweight (weighs 54 lbs.)
  • Good duty cycle
  • Standard voltage input, allowing for home use
  • Ground lead of 9 feet
  • Greater control due to the 2T and 4T switches
  • Multi-purpose
  • DC output

Cons

  • Lacks a welding chart
  • Short warranty period

Verdict

This welder shares plenty of similarities to the Hobart 140 welder, but has a few differences from it as well – but it will not exactly work for beginners because of the lack of a welding chart.

What we do not recommend

ARKSEN MIG130 gas-less welding machinedoes not run as much power input/output

There are many budget flux core welders out there, and this falls under that category – with the unfortunate aspect of not running as much power output or input. The machine is both compact and lightweight in design, like most of those on this list, but it lacks the same quality that they have. An instance is in its stainless steel body, which is quite impressive for something durable, but the welding gear itself is disappointingly on the low end of the scale.

It is sufficient for your needs if your aim is to use a light DIY home welder, but there are better options to consider. The pricing will reveal that you cannot expect too much from it, but it is enough for any metals that have thicknesses of less than ¼ inch. Just make sure to be mindful of its gas-less nature, so do not expect it to run MIG welding tasks.

Merits

  • The price range is affordable
  • DC output
  • Torch lead of 8 feet
  • Stainless steel body

Demerits

  • Low quality parts
  • Lacks a warranty
  • Can only handle maximum thickness of ¼ inches
  • Light duty
  • Short ground lead of only 6 inches
  • Low amperage output (50A)

Verdict

This welder can work for you if you are looking for a pure flux core welder without the gas aspect, or if you are working on lighter projects. However, its welding equipment is not of the best quality, so it will not work for heavy-duty jobs.

HITBOX MIG gasless welder equipmenthas versatility, but low quality build

While this is a machine that comes in quite handy for a beginner or useful as a backup machine, there are a number of disappointing aspects that it has, which is the reason why it is not a good choice.

The good news about it is its affordability, which makes it a god choice for any hobbyist welder. It can operate with 200A of power, and its arc can become hotter than what you would typically get from a 200A machine.

In addition, it can operate for a much longer period compared to other similar machines of the same size. However, it does not have as long of a lifespan, because of its low quality.

It also gives you an option to connect a TIG torch and do some TIG welding if you want, but the preset settings are unfortunately too limited to handle extensive work due to using synergic settings. Instead of giving a wide variety of settings, it comes with predetermined specified settings, which then dictate the amperage you can run and wire size to use.

The setting style is good if you are a learner, because you do not necessarily need to know the correct amperage rate to wire speed. The bad news is that you can only choose between two metric wire sizes, unlike most synergic machines that have multiple wire speed adjustment settings.

Merits

  • Can handle both MIG and TIG welding
  • Affordable

Demerits

  • Low warranty period
  • Inconsistencies in the results and the product
  • The lifespan of the welder is short
  • Limited setting adjustments

Verdict

If you are looking for a 200A machine that has beautiful welds, this can be an option to consider. However, it is not something you would consider first, as there are plenty of similar machines that have a higher quality of build and work.

What to look for in a flux core welder

Before you go purchasing a flux core welding machine, it is very important to know the reason you are buying it, and the purposes you want to fulfill – this will help you make the best choice for your needs. Another thing to note is that all MIG welders can operate flux core welding functions, as it only requires you to turn off the gas supply. However, the gas supply can still remain on if you want to give your weld some extra shielding.

Since the latter option is not necessary, having a basic MIG welder or a flux core welder is enough to accomplish the task. If you are looking for a flux core welder, here are some factors to keep in mind.

Thickness of the plate

It is important to be realistic about the range of thickness you want on the plate. You likely want to avoid a welder that can only handle the task of fusing the maximum gauge of your plate, because it will not handle welding tasks as well as a welder that can handle thicker materials. If you will need to weld thicker sheets of metal and purchase such a welder, it will leave you struggling in this case, wishing that you had better equipment to accomplish the task.

If you are unsure of what to get, the general guideline is to get a welder that has a higher amperage range, as it will allow you to weld thicker metals. However, you will notice that not all welders are the same, so it is best to get a general overview before concluding that one can weld more efficiently than another just because of the amperage.

Usage – whether it is multi or single purpose

For a typical MIG machine, you will get both gasless and gas operations, allowing for multi-purpose use. However, if you want to avoid the use of gas with your welding processes, then you are better off getting a single-purpose flux core welder machine.

On the other hand, if you want to use gas to make cleaner weld results, you should get a MIG machine that is multi-purpose, and can weld both flux-less and flux-cored wires.

The type of metal you are handling

In this case, it is important to know the metals you are primarily handling as well, because there are certain welders that handle certain metals better than others. Note that no flux-core welder can handle aluminum, unless you purchase a MIG welder that can handle both flux-less and flux-core wires. Multi-purpose machines can handle aluminum to some extent, or you can modify them to handle aluminum welds.

It will also make a major difference if the welder can handle DC or AC output, though DC outputs are better for flux core welding tasks. AC will work in certain cases, especially if you are welding steel (rather than stainless steel). If the quality of your welds is a concern to you, or you are handling stainless steel, then you are better off getting a welder that has DC output.

Quality of the lead

This will make a major difference in your weld experience, especially in terms of its durability and thickness. The longer the lead, the easier your welding task will be.

Wire differences

This involves considering the diameters of the reel and the wire. Most welders for home or light usage will run a wire of 0.03-inches in diameter and a wire reel with 6-inch diameter. If your aim is to lay thicker beads, then choose thicker and longer wires, and the welder should feed 0.035 inches. In the case of the wire reel, you should choose one that is 8 inches to allow you to make the most from it with less.

Final thoughts

Choosing a flux core welder requires a lot of thought, although a standard MIG welder can still work for you in this case – depending on your needs.
