Engine Driven Welder & Generator Combo Buyer’s Guide

Key Factors to Consider When Buying a Welder-Generator Combo

You need a unit that will meet your unique requirements. Buying considerations should include:

  • Versatility in terms of functionality and multi-processing
  • Power type, namely AC or DC
  • Engine type and the fuel you will need
  • The noise levels that the model produces
  • Generator style as it affects portability and size

Below, we will be taking a comprehensive look at the features of these machines, the options you have, and the advantages and drawbacks of the different specifications.

Fuel Consumption

An engine-driven power producer will use one of three fuel types, namely gasoline, diesel, or liquid propane (LPG.)

Most small and portable units run on gasoline. Gas engines typically yield a relatively low fuel consumption and they start easier to use in cold weather. In addition, gasoline is more affordable than diesel or propane.

Diesel is the more affordable fuel type for jobs that stretch over more extended periods as it is the fuel that provides the longest run-time. If the fuel is supplied at the site, the chances are that you will need a diesel engine.

Despite being the most expensive fuel type, propane offers several benefits. Propane burns cleaner than other fuel types, it can be stored for a long time, and you can use it in areas that are not well-ventilated.

Weight and Design

As a rule, the more powerful a unit is, the bigger and heavier it will be. This is simply the result of the added components needed to increase welding power. The design of the unit can also significantly affect portability, weight, and size.

There are two design types. The first is an open or tube frame and the second is an enclosed casing. Tube frame welders typically weigh less than enclosed ones, and they are also generally more compact. However, enclosed casings offer better protection to engine components than models with open designs and their noise levels also tend to be low.


Portability is an essential buying consideration if you carry out welding jobs at different locations. If you have to haul a powerful unit around, it may make sense to mount it on the back of your truck.

The design of the device can impact portability. Tube frames tend to be lighter and more compact then enclosed cases, and you can easily lift a tube frame with a crane or your hand. Some designs feature compatibility with wheels for added portability.

Enclosed designs usually have carrying handles, and if the machine is light enough, you may be able to carry it with one hand. Pay attention to the weight specifications before buying.

Price Point

The price tag is naturally one of the most important considerations when shopping for a machine. It should not be the only consideration, however, as you may end up with sub-par quality and limited functionality.

Welder power combos are at a higher price point than electrical machines, primarily because you can use it away from a shop, such as on a farm or somewhere in the field.

You can expect to pay more for products that are powerful, high in quality, and from reputable brands. You will also likely pay more for multiple processing and fuel efficiency. But you will end up saving on running the machine and component replacement costs over the long run.

Power Output

When it comes to the power output you require, the processes you intend to run are very significant. Welding processes include stick, TIG, and MIG wire feed welding. Some multi-process welding machines can run multiple operations as well as plasma cutters.

In addition, you may want the generator to power equipment, such as a generator or grinder. If, for example, you plan on only doing basic stick welding, there is no need for a 20kW phase. On the other hand, if you need power for multiple processes and additional equipment, you will need a significant amount of power output.

Duty Cycle

A machine’s duty cycle indicates how long you can run the welder continuously at a given amperage within a ten-minute cycle. If, for example, your welder’s duty cycle is 30% at 200 Amps, you must rest your welder for around seven minutes after three minutes of continuous welding.

Most often, the cycle duty goes up as the amperage goes down. At low amperage settings, you will be able to run the weld for a much longer duration before your machine cuts out.

If your machine supports multiple processes, the duty cycle will be the same for every process.


When buying a new unit, you may need some accessories to support the processes or to make your job easier.

The most common accessories for welder-generators include extension cables for remote control operation, carts or trailers for heavy units, cylinder tank racks and hose assembly for LP gas models, as well as a portable wire feeder, welding gun, and connector kit for MIG wire feed welding.

Accessories for stick welding include electrode hoses and clamps to increase the working radius. If you have a TIG function, you may consider accessories such as a TIG torch and tungsten electrodes, as well as collets and nozzles.

Power Type

AC and DC refer to the polarity of the electrical current that the machine produces and that runs through the electrode.

DC is electricity that flows in one direction and that has a voltage with consistent polarity. AC, on the other hand, is electricity that switches direction and that has a periodically reversing voltage. With AC welding, the arc is, therefore, not affected by magnetism.

You need an AC welder for welding magnetized materials, TIG welding aluminum, and applications such as machine repairs and seam welding.

DC is the more commonly used power type as it produces a smooth weld and a stable arc. DC machines are also more affordable than AC, and they are easier to use.

Noise Levels

Engine-driven units are louder than electric ones. If you are working in a remote setting, say, on a farm, it is no use compromising on power for the sake of keeping the noise level below 100dB. If you live in an apartment complex and you do most of your work on Sunday afternoons, however, the noise level becomes a significant consideration.

If you are working around other homes, stick to a unit that produces a noise level of no higher than 90dB, which is louder than a vacuum cleaner and more or less the same as the volume of city traffic.

Noise Protection


Before purchasing a welder, you will want to ensure that the machine and the engine come with a warranty of at least two to three years. Manufacturers provide a warranty for each component, so you will often find that components such as engines and batteries are warranted separately.

Most warranties are pricey, and when there is an issue, most companies will ask you drop your unit off at the nearest service center for a free repair, which may be in Asia if you bought a cheaper model. However, brands like Hobart offer high-end warranties, which may be worth your while.

Fuel Can

One of the most significant benefits of welder-power combos is that you are entirely location independent. You can carry out welding jobs anywhere: on rooftops, somewhere in the field, or even roadside.

If you are out of fuel, however, not even a nearby electrical outlet will help you. Therefore, we highly recommend that one of the first multi-process components you purchase is a fuel can to serve as a backup fuel source.


While doing a welding job, you have to move around to reach certain areas. If your oxygen and acetylene hoses are too short, however, you will have to move your welder with you continually. If you have a heavy and bulky machine that is not on wheels, it can waste a lot of valuable time.

High-quality welding hoses of fifty feet or longer will allow you optimal mobility without the hassle of having to adjust the position of your device.

Welding Clamps

After spending a lot of time and money on finding and buying the perfect welder, you will want to ensure that your welds are neat and tidy by preventing materials from shifting while you work.

With welding clamps, you can keep metals fixed at specific angles and in the correct position to prevent mistakes. Welding clamps ans metal working tools are incredibly valuable accessories for multi-process welding. They are also affordable and readily available.

Multi-Process Components

A Protective Cover for Your Unit

You need sufficient protection for your multi-process welding machine during down times. A weather cover will prevent the accumulation of dust and corrosion, and it will keep moisture out of the unit components.

A protective cover will not only prolong the lifespan of your unit, but it will also ensure optimal performance for longer. Deterioration as a result of exposure can lower the unit’s duty cycle and increase the risk of defects.

Extension Cords

If your welder-generator combo produces sufficient power, it may be able to provide power to other tools such as grinders, plasma cutters, and drills.

If you don’t have a quality welding extension cords with enough length, however, you will not be able to carry out your work effectively in remote settings. Heavy duty extension cords can go a long way to save you time during a project, especially if you are one of two people working together.

Running Gear

If you work alone, moving a heavy machine around requires a lot of energy and can waste a lot of time. High-quality running gear, such as wheels or dolly-type fittings, is a must-have if you have a heavy and bulky welder-generator.

While some units are not fitted with running gear, they have mountings that you can use to attach rollers. Wheels will make transportation and position adjustments effortless and, since you won’t pick up the unit, it will prevent the risk of personal injury or damage to the unit.


As a small construction business owner, DIY enthusiast, or hobbyist, you need a high-quality unit that is capable of producing a neat arc and that is portable and durable.

If you need a welder for general repair work or maintenance, chances are that you won’t need more than a stick welder. There is no doubt that a high-end unit like the Lincoln Bulldog 5500 will be more than sufficient.

When it comes to aluminum or metals that are magnetic, you have to purchase a unit with an AC welding output and support for TIG.

For industrial, commercial, or heavy-duty applications, we recommend the Lincoln Electric Ranger 305G or the Miller Trailblazer 325. These two cutting-edge models have sufficient power and support for all processes.

These models are also fuel efficient and durable, so the high price you pay now will be offset by the low running costs over the long-run.
