Factors to Consider When Buying the Best Portable Generator for Welder

Even with the above review, there are critical factors that you need to consider before settling on any of the above brands. Read on to learn more.

Fuel source

best portable generator for welderMost portable generators are gasoline-driven; however, some models also run on propane gas and diesel. The type of fuel that your generator for welding uses will impact the overall costs of your project. For instance, diesel is an affordable fuel source, and it is readily available. However, diesel-powered generators are noisy. Propane gas, on the other hand, is the most expensive fuel source among the three. However, it burns cleaner than the rest. Additionally, propane has a longer shelf life than diesel and gasoline. Some models can run on both propane and gasoline.

So, check on your preferred fuel source before settling on any model.

Fuel Consumption Rate

Another factor that can affect the cost of your project is how much fuel your welding generator consumes. Most portable generators for welders are powered by gasoline because they have a high fuel efficiency rate, portable, and operate quietly. Check on the generator’s description to understand the unit’s fuel consumption rate.

Type of power

When shopping for a generator for welding, you should be keen on whether it produces AC or DC. This is because all welding machines don’t require a similar current. For the best service, choose a generator that matches the current requirements of your welder equipment. If your welding machine handles both AC and DC, choose a generator with a similar output. Moreover, you should also check the amount of power output the generator delivers. Check on your welder’s power input demands and other appliances you’ll be running and compare with the size of generator you’re shopping for.

Check on portability

A generator for welding should be portable so that you can move with it wherever there is work for you to do. The weight of the generator is one of the leading factors affecting the portability of generators. Robust and heavy-duty generators are heavier than light-duty generators. An ideal generator for a welder should be easy to lift and transport. If you settle for a heavy generator because of your power needs, consider installing it at the rear of your truck.

How noisy is the generator?

Suppose you’ll be working near a hospital or residential set-ups. In that case, the amount of noise generators produce is a critical factor. Encased and compact generators operate quietly because the casing dampens the engine sound, unlike open frame designs which are noisier. Even though the noise a generator produces is a crucial factor, be careful not to compromise on the power output of the generator.

Frequently Asked Questions

What is a welder generator?

It’s multi-purpose power equipment that can work as a welding machine and be used as a generator when there’s no power. When you’re not using the equipment as a welding machine, you can run it as a generator to power your tools and other appliances.
