Can you weld with a generator?

Some welding tasks cannot be moved to a workshop, especially if the pieces are outdoors. This is where portable generators come into play. These generators create a power source capable of powering the welding tools. They are useful in places where there are no electrical outlets. Think of them as portable welders.

How can you weld with a generator? The first step is to buy a generator that produces enough amps to run a welding machine. Then you can plug in your welder and move it to where it is needed. If you don’t want to connect a separate welding machine to the power source, you can purchase a welding power source with an integrated welding kit.

Using power sources for welding can sometimes be tricky. This is why it is very important to know how to weld properly with a generator.

Using A Generator for Welding

Welding generators use fuel for power instead of the electrical grid. They are considered essential tools for industry and construction. Farmers also use them to build or repair various objects. It works like a normal generator;  all you have to do is fill the tank and turn it on where you need it.

One of the benefits of having a welding generator is that it can be used as a stand-alone generator. This means you can use it for other power tools or to power home appliances. It can save you space and money. Most welding machine generators can run:

  • Mig
  • TIG
  • Flux-cored
  • Stick
  • Plasma cutters

Some welding power sources are equipped with a complete welding kit. This way, you don’t have to worry about connecting a separate welding machine.

What You Need To Look For In A Welder Generator

These are some tips to consider when buying a welding generator:

  • What fuel do you make use of?
  • Does it come with accessories?
  • What is its amperage?

Most of the smaller generators have engines that can run on gasoline. Gasoline is much cheaper than diesel or propane. Diesel generators are primarily used for industrial-grade equipment and larger jobs.

If you are using a generator frequently, diesel may be a better long-term option since it burns slowly and lasts longer than gasoline and propane. Remember to check and ensure there is sufficient ventilation to disperse emissions.

Some generators come along with accessories or a complete welding kit, and some can be supplied as stand-alone generators. If you are just starting and don’t have many welding tools, accessories can be helpful.

Keep an eye out for amperage information. Smaller generators will have lower amps than (larger) industrial generators. If you plan to weld occasionally or on light materials, you won’t need the industrial-grade welding generator.

If you weld frequently, then the industrial grade would be an ideal choice. It is capable of running for 6-12 hours (depending on the size of the fuel tank).


It is important to store your equipment properly; keeping it safe and dry when not in use will prevent damage and wear caused by the elements.

If you have to leave your equipment on an outdoor construction site, it would be a good idea to cover it with a tarp or waterproof material.
