Best Welder Generator Buying Guide

Welder generators use different electrical and mechanical properties. So, while purchasing, you need to have a clear understanding of these properties.



This is the place where you need to blend the juice to take out the power. You can measure the reliability of an engine easily. And if you want to get the best-quality engine, you have no other choice to choose a renowned brand. Kohler, Hobart, along with some other brands, are well-known engine manufacturers.

Another point you need to keep in mind is, a good engine will cost higher.

In order to accomplish a regular welding job, the 10HP engine is a must. 12HP – 20HP engines will provide you more compelling work. And from these engines, you will get a minimum of 5,000W continuously, and their peak will be more than 8,000W.



Firstly, learn what the fuel requirement of the engine is. For many generators, Gasoline is the most popular fuel source. OH! I forget to let you know, diesel is also similarly popular.

Also, make sure you are allowed to run generators in your region.

It is evident; more fuel capacity means better performance. The standard level of fuel capacity is 7 gallons. And every gallon should be able to upkeep the welder generator at least for 1.5 hours with 4,000W continuously.

Moreover, it would be best if your selected welder has any sort of fuel measuring system.


Duty Cycle

Following the duty cycle, you will be able to measure the break time of a welder generator after every continuous phase of operation. If a welder says, its duty cycle is 40%, know that you need to give it 6 minutes of rest after 4 minutes of constant operation. The minimum expectation level of duty cycle is 30%. And the maximum measurement level is 100%.



Generally, the welding machine comes with the welder machine. But all machines don’t contain the full set. You will get some tools with your purchased welder generator and balance you may need to purchase separately.

Below is the list of tools a welder generator may contain

  • Pieces for connection.
  • Hand gloves.
  • Funnel for oil.
  • Cover (water-resistant).
  • Tools for old weather.
  • Running gear.
  • Hex wrench (small-sized).
  • Fast connector.

Remember, from the above list, cover (water-resistant) and running gear is both must-have accessories with the welder. Also, if you are staying in a cold-weather region, you should get tools for cold-weather along with the welder generator.


Built and Maintenance

There is no doubt when you are purchasing an expensive product; you will not compromise the product durability. So, the device should come with a robust metal case. A totally enclosed casing will be durable without any confusion. There should be few openings to give you a chance to do maintenance work.

Also, the device has to be lightweight so that you can carry it if required. Besides, there should be any resistance to keep the batter safe from water damage.



You may get a lot of complaints from the neighbors due to the high sound created by the welder generator. So, choose a welder generator that doesn’t produce sound more than 80dB.
