The inclusion of an enclosed case with 3 service access doors for keeping the engine fully protected stands out as the highlight of the product. 

However, the lack of ‘chopper’ technology could have been added since it is crucial in smoothing out the welds.

Overall the welder generator is suitable for various welding jobs and can easily provide an operational capacity for 12-hours straight. 


  • Ideal for MIG, TIG, and Flux-Cored welding
  • Outputs for both AC and DC
  • Performs powerfully with 10,500 Watts peak generator power

3. Hobart Champion Elite Arc Welder Generator 

The Champion Elite Arc Generator is one of the most popular multipurpose generators by the brand Hobart. It is a mobile source heavy-duty generator which can simultaneously do your welding jobs. Also, it provides the necessary on-site power for running your tools and equipment.

The machine measures 41 x 20 x 28 inches and weighs 493 pounds, which is quite less than other heavy-duty generators. The machine is so impressive in its performance that it is capable to perform almost any type of light or heavy-duty welding job effortlessly.

It comes with a portable engine-driven solution with 23HP Kohler twin cylinders. Generators, be it professional or even weekend warriors can use it to work on household repairs, garage projects, yard art projects or even auto body works.

Now coming to the performance, it runs on a gasoline engine with a fuel tank capacity of 12 gallons. The average rated output is 225 Ampere @ 100% duty cycle. Whereas, the ampere range falls between 40-225. 

It impresses us with its powerful performance, all due to its 11,000 watts of peak power in the single-phase generator which is extremely useful for running tools or work lights or even to be used as backup power during an outage. It delivers 9,500 watts of continuous power generation, making it as remarkable as any other top welder generator. 

Among the features of the machine, it’s the huge fuel capacity, enclosed design and strong electrical connection which makes this machine sturdy in enduring heavy-duty tasks. Even though it functions ideally for professional uses, it’s simple and easy to use features and application makes it even ideal for beginners as well. 

Overall, the Hobart Elite Arc Generator is in itself a complete package, working both as a powerful welder and generator. The good news is that you will be getting both these features at the same price, without having to purchase each separately. 

In short, with an industrial or professional-level performance, this machine is unmatched given the compactness of the product.

With dimensions of 42.3 x 21.5 x 36.2 inches in measurement, the machine surprisingly weighs only 8 pounds. This makes it more convenient to move to and from between your work and home garage.

The use of Lincoln’s Chopper Technology gives it an edge over the Ranger 225 generator in superior ARC performance. This technology helps carry out a smooth and reliable arc in welds as well as for a low spatter and praiseworthy bead appearance. 

The machine is a powerhouse when it comes to providing welds with extreme precision. You must be wondering why I call it a ‘POWERHOUSE?’ Well, the answer lies in its capacity to produce 9500 Watts of continuous power and 10,500 surge watts.

This makes the generator a powerful one that can be used to run or power equipment, lights, or even for grinding equipment and other tools at a welding site. 

The 12-gallon fuel tank runs on gas and not diesel and can easily work up to 10-12 hours on continuous use.

5. Tomahawk TWG210A Welder Generator

The TOMAHAWK 15 HP Engine Driven Portable 3,000 Watt Generator is an ideal welder generator, especially for welding enthusiasts and weekend warriors. We say this because the generator is ideal for smaller jobs and is highly convenient to move around.

Welders which are involved in farm works, home garage or even fab garage often choose this machine over others since it makes the overall job easy for them. 

You can even use it on construction sites or any job site requiring electrical power and CC (constant current) stick welding. 

Weighing only 154 pounds and measuring 23 x 21 x 28 inches in dimension, this engine-driven inverter generator operates at a stable sine wave resulting in steadiest welding. 

Coming to the product specifications, the machine comes with a 15 HP Inverter Engine, operating at 120V and rated 210 Amps. But the 2000 watts DC power output makes it not convenient for industrial level welding works or even other heavy-duty welds work.

How to Choose the Best Welder Generator in 2021?


Welder generators come in various sizes, and thus with various different functions and uses. The larger the size, the more uses and functionality it will guarantee.

But this has its own disadvantage as well. A large welder generator will be less portable than medium or small-sized ones.

For small jobs like a home or garage, a small to medium welder generator will be fine. Whereas for industrial level jobs where you don’t much focus on portability, a large welder generator will be a more ideal choice. 


Most of the welder generators fall between 2000 to 20,000 Watt power range. Choosing a power range will depend on the kind and range of tools that you use. And, also if you want to simultaneously run and weld tools.

A 2000 Watt generator would be ideal for running grinders, whereas, for air compressors, a generator with at least 8000-1000 Watt power will be necessary. 

So, depending on the type of tools, the power capacity will increase with the increase in the complexity of the welding process.


The most common process for which generators are used is for Stick and Flux Cored. Stick has the most simple equipment use and easy to use. At the same time, Flux-Cored is used in heavy-duty applications and is more fuel-efficient. 

But most welders opt for generators that provide multipurpose use in MIG, TIG, Stick, and Flux Cored. Machines with 250-300 AMP are able to give sufficient power for all kinds of jobs.

Fuel Tank

This depends on what kind of fuel you want to use for running your welder generator. Most generators have engines that run on gasoline, diesel, EFI, or even LPG. Gas engines come with an added advantage as they offer low product cost, weight, and size. 

Whereas diesel engines are more fuel-efficient and use 25% less fuel than other engines.

A generator that runs on EFI (electronic fuel injected) gas uses even less fuel than diesel ones, which is a major benefit for those with a restriction on storing fuels on-site.


Portability becomes an issue for those looking for generators that can be easily moved between different spaces. 

Those welders who are involved in a job that requires more travel should opt for a lightweight machine. Whereas those who are okay with a bulky machine will not face this issue.

Who Should Buy A Welder Generator?


Besides professional and welding enthusiasts, these generators are extremely useful for those farm regions lacking an external power supply.

With these generators, farmers can run their farm equipment like seeders, turbines, irrigation pipes, and many others.

Construction Workers

The welder generators can also be used at construction sites with no external power supply. Workers at such sites can use these generators’ power for framing or constructing support for the building. 

What are the Benefits of Welder Generators?

Construction and Industrial Works

The welder generators can be used to create frames and construct steel support for the buildings on construction sites. Industries, where there is a lack of external power sources, can use these welder generators to construct or repair metal structures or components.

Emergency Power Backup

The welder generators also provide the benefits of a power backup in case of emergencies. Apart from welding, these generators are increasingly being considered as an alternative source of power supply. 

In cases of long power cuts during tornadoes, heavy rains or due to other reasons, these generators can be used as the great power backup.

Starting up Big Appliances

Many powerful welder generators come with enough power capacity to be used in a house or small local business. These generators come in handy in starting up bigger appliances like water boilers, air conditioners, furnaces, etc.

Summing it Up

The best welder generator that tops my list is the Miller Electric Bobcat 250. This generator has aced all my parameters with its excellent power capacity, high durability, a large fuel tank, and multi-purpose use.

The article reviewed the best welder generators you can buy for your home or work garage. All of these machines are worthy enough to be brought to your workplace and are guaranteed to give you a satisfactory welding experience.
