1. Lincoln Electric Ranger 225 Multi-Process/Welder Generator – Overall Best
Engine: This engine driven welder-generator combo from Lincoln Electric comes with a powerful 23 HP Kohler 2-cylinder engine. It has an air-cooled system to keep the engine cool during operation. Also, the engine is fully protected under a totally enclosed case. But three access doors allow the users to service the generator easily.
Welding Capability: It is a small welding machine that suits ideally for heavy works. It is capable of doing TIG, MIG, and flux-core welding.
TIG (Tungsten Inert Gas) is an arc welding process where the Tungsten electrode (non-consumable) is used to produce the weld. This type of welding needs two hands of the users. One is for feeding a separate filler material onto the weld. And second is for holding the welding torch.
On the other hand, MIG welding is easier to perform as you only need to feed the wire electrode continuously from a spool gun.
Also, this welder generator can help you to do flux-core welding that is an automatic or semi-automatic arc welding process.
Welding Amperage Range: It has a welding current range is 50 to 225 Amperes for versatile use. Ampere is the unit of current.

In order to buy a welder-generator combo, it is essential to focus on various factors to get the best possible machine. So, what are those factors? In this buyer’s guide section, we are going to discuss them.
Design and Weight
The weight of the engine-driven welder-generator combo depends on the power output. A unit with more power is always heavier and bigger in size.
Now, come to the design of the generator. Enclosed frame generators are best in case of protecting the engine and parts. Also, these units tend to create less operational sound. On the other hand, open frame machines are lighter in weight than the closed frames, but they produce more sound and offer less or no protection to engine and parts.
Using welding generators on job sites need wheels so that welders can easily move their machines from one place to another. It is really impossible to move a 400-pound machine without wheels. So, the portability factor is always important if you are a professional welder who works at construction sites.
Manual and electric start systems are common in welder-generator combos. You are required to use your hand power to pull the generator cord and start your machine manually. But the electric start is reliable and a more comfortable option.
Power output depends on your welding work. Powerful machines help you to run various processes that include TIG, MIG, and stick welding. Also, some generators allow you to run plasma cutters as well. So, if your welding work is demanding, you should go for a welder generator with higher power output like 10K, 15K, or 20K. Or if your work is less demanding. Means, if you only require a generator to do basic stick welding, then a less powerful generator would be enough for you.
Type of Power
You must also need to decide whether you require an AC welder or a DC welder.
For smooth welding and to produce a stable arc, you need DC power. And For TIG welding or welding magnetized materials, you need AC power.
Keep in mind that DC welding generators are easy to use than AC machines, and they are also affordable.
The duty cycle refers to the number of minutes a welder generator can operate non-stop out of a 10-minute period.
Your machine will be able to weld for longer at low amperage settings and for a shorter duration at high amperage setting.
Type of Fuel
What type of fuel is best for your welding generator?
Gasoline, diesel, and liquid petroleum gas (LPG) are widely used in engine-driven welder-generator combos.
Gasoline is easy to use, but it is dangerous than diesel. Also, it requires more maintenance. On the other hand, diesel gives more runtime and requires less maintenance than gasoline but a diesel generator is more expensive.
If we talk about propane, then it is less efficient than both the other fuel options, but you can store it for a longer duration.
Fuel Tank Capacity
A big fuel tank will give longer runtime than a small tank. So, if you are a professional welder, you should go for the big tank size.
The sound rating of a generator also needs to consider. If we compare engine-driven machines with the electric ones, then we will find that engine-driven units create more noise during operation. So, you cannot get a less noisy engine-driven welding generator. But try to stick to a machine that operates within 90 dB (A).
