What we do not recommend

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.

Types of welding processes

In order to have an improved understanding of multi-process welders, it is important to know the different types of welding processes. They are three, which are:

TIG welding

Also known as Tungsten Inert Gas welding, this uses an electric torch alongside a tungsten electrode, which then gives the welding arc some power. You then add a filler rod, and this will weld the metals.

As a shield gas, you use an inert gas, usually argon – this will also act as a coolant for the weld puddle and protect it from contamination or oxidation. The method does not produce as much heat as MIG welding, and this makes it great for lighter metals and their alloys.

MIG welding

This involves the use of a MIG welding gun and spool wire when welding the metal. It can be used for a variety of surfaces regardless of thickness, such as stainless steel, nickel, or even aluminum (in some cases), and is among the easiest welding methods to learn.

However, it cannot be used for all metals because of the very high temperatures it produces, which can destroy lighter metals and alloys. In addition, the results must be free of corrosion, because the process is not weather resistant.

Stick welding

This involves the combination of the work piece and an electrode, and they are subjected to high temperatures until they melt, then the mixture is welded. In order to prevent contamination of the mixture, you use flux core to coat the mixture.

The process is the most heavy-duty of the three, and it is usually used when you are welding very heavy or thick metals. It also generates a lot of heat – even more than MIG welding. The process is also quite challenging to learn, because you will need to control the different elements of the process.

Benefits of a multi-purpose welder

The truth is, purchasing a multi-purpose welder is not the easiest task – in many cases, it can end up being more challenging than buying a welder that specifically caters to a specific welding method. But, like any other purchase, it is important to consider a few factors before making your purchase.

Before doing so though, it is great to start from knowing what makes a multipurpose welder unique from other welders, and the advantages they offer you as well.

Gives versatility

This is the reason why these welders exist – to offer you a wide array of options you can use during the welding process, without forcing you to look for equipment catering to that specific task. This is due to the fact that these welders can handle several combinations, such as flux core, MIG, stick, and TIG welding, all in one machine.

Extra convenience

These welders should make it much easier for you to accomplish a variety of projects in your workshop or construction site. This is all because of their ability to change according to the present needs, so you can adjust their use according to your needs. You will also not need to change the power sources when you are working of different tasks.

Due to this, both professional and amateur welders will appreciate the convenience these machines bring to the job.

Space saving

The main problem of having multiple machines that all look similar and some functioning in similar ways is that they can occupy a lot of space in your workshop or storage, and it is tiresome to keep arranging them all the time. A multi-process welder will help to save this space, because one welder fits a multitude of needs. It will also help during transportation, since you will not need to carry a host of welders in your car.

Economical

These multipurpose welders can prove to be more costly compared to the specialized welder types in some cases, but this is ultimately negligible to buying a ton of different welders to cover a specific task. In the long term, a multi-process welder will save you money, as they perform a variety of tasks at a go using the same equipment.

What to consider when choosing a multipurpose welder

Portability and weight

It is easily understandable that buying a multipurpose welder means that you are taking on a variety of projects, so portability is good to consider for many cases.

Even though the chances of finding a truly lightweight welder are slim, you need to search for one if you are going to move around with it frequently.

Welding process and technologies

Different multipurpose welders will offer different welding styles, with some offering up to 4, though you need to manage the expectations you have if you do not want to spend so much. For many cases, you will turn to a multipurpose welder to save the costs of buying multiple single-use welders.

These welders can feature a wide array of combinations – although the most common combinations are stick, MIG and TIG applications. Some welders will have a plasma cutter function, though this will have a medium or low output, which you can use when welding aluminum, medium or thin thickness metal, or going through rust.

Overload protection mechanism

For any welder, it is a must that it has overload protection to guard against overheating. In multipurpose welders, this is even more important because the machine can easily wear down due to overheating.

Dual voltage

This can seem minor, but it is a game-changer in many cases. In particular, it can really help you if you want some freedom of working without depending on one specific outlet type.

For higher output reasons, it is great to get one that uses 220 volts as well. This will allow you to cut through the thicker metals in one pass, since the circuit is powerful enough to sustain the job.

Duty cycle

There are some welders that will have their duty cycles listed, though it is not as important in this case. Since you are using more than one welding style, the cycle will not be as consistent throughout – and there are other output ranges you will need to consider.

Price

These tools will rarely be cheap, since they are offering you a lot of functions. While there are some models that are budget friendly, they will often make some compromises that make your welding tasks more difficult.

The more expensive options are the most useful, at the end of the day. This makes sense, because it will save you money in the long term, especially if you are not using the welder to complete a heavy duty task.

If you are planning on doing industrial style tasks, then you are better off purchasing multiple welders that are dedicated to the task, which ensures good performance and longevity.

Other factors to consider

The metals it can handle

Different welders can handle different metals – while some focus on one metal, others can do several efficiently. The usual metals you will find welders handling are aluminum, stainless steel, and mild steel, while some welders can handle cast iron, iron, and some alloys.

Control of heat (TIG)

To achieve a good quality weld, it is very important to control the heat output of the welder itself. This is particularly important if you are working with metals that are more delicate, as too much heat will warp them.

Thickness of the materials/metals (MIG)

There is only so much you can expect a welder to handle. As a general rule, MIG welders can comfortably handle thinness of 0.0239 inches (24 gauge) or 0.0478 inches (18 gauge), and maximum thickness of 1.2 inch or 3/8 inch. If you are welding metals that are thicker than this, you are better off getting a stick welder machine.

Final thoughts

The best multi-process welders can handle all your projects easily, so getting one that has at least three welding technologies available and dual voltage input is a good place to begin.
