Things to Consider While Buying the Best Generator for Welding

So before choosing the Best Generator for Welding, you should keep the following factors in mind in this buyer’s guide because it will help you to get the best generator that fulfills your demands.

Power Output

A welder generator’s pricing is often determined by its power output. The price rises in direct proportion to power production. The more economical welder generators typically have a lower power output because they are designed only to power a welder. But more powerful welders can power additional tools like an angle grinder or even a plasma cutter.

A/C/DC Power

The terms AC and DC welding in the context of welding relate to the types currently employed during arc welding. For welding with less spatter, DC output produces an arc that is more stable and smooth. This is because a DC flows in one direction with a constant polarity.

Contrarily, welding with AC power produces significantly more splatter than under DC power and is slightly less smooth. However, because it cleans the oxide off the metal’s surface, it fixes arc blast problems and is much better suited for welding aluminum.

Before choosing a welder generator for your purposes, keep in mind that while the majority of them can switch from DC to AC power as necessary, some only offer one type of currency.

Duty Cycle

The period the machine can run risk-free at a particular amperage is referred to as the duty cycle. The amount is given as a %; the lower the percentage, the shorter the period the welder generator can be utilized before shutting off after its cycle is complete. This is yet another crucial aspect to take into account while evaluating engine welders.

Things to Consider While Buying the Best Generator for Welding

Ability to Weld

Given that stick welding is the most popular type of welding performed with them, most engine-driven welders will primarily serve as stick welding machines. Powerful enough to handle specialized welding procedures like TIG welding are some welder generators. Some also can support flux core welding when using a MIG welder. However, it’s crucial to use the proper welding leads and accessories when MIG or TIG welding.


A more powerful unit will cost more money, but it will have greater battery life and more appliances it can power before it has to be refueled. There is a wide price range for generators, from a few hundred to several thousand dollars.


You should make sure of the longevity of your business’s generator as it represents a big investment. Commercial generators often have shorter one-year manufacturer’s warranties. The DUROMAX generator stands out as the only model on our list that offers a commercial guarantee longer than 3 years.


Many welders require a generator to carry outdoors to power the welding machine while performing repairs on farms and other isolated locations. It should be lightweight and durable enough to resist adverse conditions for this use. The majority of generators have wheels so you can move them around with ease even though they are often quite heavy (some weigh over 500 lbs).


The last thing you need is a noisy generator that makes earplugs necessary. Most of the above generators are not particularly noisy.

Best Generator for Welding – FAQs

What size generator to run a welder?
The minimum generator size advised is not less than 7kva.
How many watts do you need to power a welder?
A 90-amp welder should produce 25 amps of current at about 120 volts of output, keeping in mind that volts are comparable to pressure and watts are equivalent to rate.
What size generator do I need to run a 225 amp welder?
You would want a minimum of a 15,000-watt AC generator to run your AC/DC 225/125 welder effectively.
How often should the generator be serviced?
The frequency of maintenance may vary depending on the brand and model of your generator, but as a general rule, it should be maintained every 6 to 12 months or after 500 hours of use, whichever comes first. Spark plugs should be changed in a portable generator every 100 to 150 hours.
How does a welder generator work?
Without relying on mains energy, a welder generator generates power for welding. Just add fuel to the tank as you normally would. The welder generator can power your welding equipment anywhere you need it by simply filling the gasoline tank, as you would for a typical generator.
Will a small generator run a welder?
Inverter welders can run on generators with low THD ratings (6% or less), which have “relatively” clean power. Inverter welders shouldn’t be powered by generators with a high THD rating (greater than 6%), as these are likely to be low-quality machines.



To sum up, there are a lot of considerations you need to make when selecting the best welding generator. First, think about what you’ll use it for, such as camping excursions or emergency backup power. Consider how much energy you will require next. Consider the unit’s size and weight as well, to finish.

On our list of the top welding generators available, the Lincoln Ranger 330MPX Engine Welder Generator is at the top. It is a compact, portable device ideal for use in longer power outages. Additionally, it is not too noisy, so you won’t have to be concerned about its usage.

A-iPower SUA12000E 12000 Watt Portable Generator is a fantastic alternative if you need additional power output, and RV enthusiasts will find it especially appealing. It has an amazing run time and fuel capacity.
Our choice for the best value is the DuroMax XP12000EH Generator-12000 Watt Gas or Propane Powered Generator. Despite being one of our more economical alternatives, this generator still has a strong watt output. You may buy with confidence knowing that the generator is covered by a 3-year warranty.

You now know which welding generators we think are the best on the market. We are sure that one of these units will meet your needs.
