Owners praise the easy starting and quiet operation of the 10 horsepower Briggs and Stratton engine.
Hobart equipped the Champion 145 with a big 6.25-gallon fuel tank, giving it hours of uninterrupted operation. There’s nothing more irritating when you’re in the groove than having to stop everything and shut down to take a refueling break.
Two things that owners didn’t like were the fact that this engine welder comes without any welding leads and the poor quality of the wheels mounted on the machine (full review here). While most users will probably load it into a truck and move it around in storage, you may want to actually take advantage of the mobility of the welder, so it really should have better wheels on it.
The Hobart Champion 145 is extremely durable, made in the USA, and comes with a 3-year warranty at a great price.

The Klutch 7500K Arc Welder/Generator uses a 429CC Kohler gas engine to spin the generator, and it puts out a respectable 6,000 watts of continuous power. That’s enough power to weld up to 3/8 inch steel and run your handheld power tools.
Engine-driven welders tend to weigh over 400 lbs., even the small ones. But the Klutch 7500K weighs just 230 lbs.
That makes this unit your choice if you do need to move the welder often as you work. Plus, the included running gear lets you roll the machine around like a wheelbarrow.
The two negatives for some users are that the Klutch 7500K only welds using a DC stick process, and its duty cycle is 30% at the maximum amperage. But for those who need to do things like weld equipment out in the middle of nowhere, this is plenty to get those remote jobs done.
On the positive side, the Klutch 7500K can arc weld stainless and mild steel, hard surfacing, aluminum, and cast iron. This versatility to remotely weld various types of stock combined with an attractive price tag will appeal to many.
As a bonus, Klutch manufactured this affordable engine-driven welder rugged enough to handle the rigors of welding in unusual places. Plus, they back it with a 3-year limited warranty (2-year limited warranty on the engine).

- AC TIG welding of aluminum is only possible for “non-critical” welds
- Doesn't include welding leads
- Weighs 485 lbs., need a trailer or truck
- Expensive after adding the optional welding leads and accessories
The Miller Bobcat 225 is geared mainly as a stand-alone generator or an AC/DC stick and DC TIG welder. You can AC TIG, but Miller states for “non-critical” applications only. If you need to TIG weld aluminum, this may not be your best choice.
With the right accessories, you can also MIG or flux-cored wire weld. However, welding thin stock is not its forte.
This unit includes a handy remote that lets you turn the twin-cylinder gas engine on or off from where you are working. That saves gas and eliminates unnecessary noise when the generator is not needed.
The generator puts out 9,500 watts of continuous power. As a stand-alone generator that can run your power tools or a compressor, blower, etc. With 225 amps of welding power, you can also do some serious welding. Plus, a 100% duty cycle keeps you welding instead of waiting.
The unit does not come with any leads or accessories; you must buy those independently, depending on your needs. But you do have the option to TIG, MIG, stick, or flux-core weld.
A GFCI version of the Bobcat 225 is also offered by Miller for those worried about or are at increased risk of electrical shock.
As for portability, this welder/generator requires a trailer or truck to transport it like other welders in this class. Miller also states they designed it for farm/ranch, maintenance and repair operations, and work trucks, and the included features/benefits certainly back this claim up.

- Users like the safer, low noise levels
- No AC TIG welding for those who weld aluminum work
- Doesn't include welding leads
- Weighs 460 lbs. and requires a trailer or truck to transport
- Expensive after adding the needed accessories
The Miller TrailBlazer 325 brings lots of power and many welding processes all in one machine. But there is no AC TIG. However, this welder accepts a spool gun if you need to weld aluminum.
The Trailblazer 325 also comes with a couple of remote options to control the generator and the welding settings. Minimal running back and forth to the welder/generator keeps you working.
Plus, you can air carbon arc cut or gouge with this unit. Some might use a separate plasma cutter plugged into the generator. But this machine gives you a “built-in” cutting method that may eliminate the need to carry around a separate unit.
An EFI engine option offers better fuel efficiency as well as smoother starts, even in adverse weather. You can also get an LP engine if that is your fuel of preference.
The welder puts out up to 325 amps of power and the generator pumps out 10,500 watts of continuous juice. That is enough for many professional applications, including fabrication, maintenance, repair, structural steelwork, sheet metal, and pipework.
For pipework that needs clean, flat welds, Miller also includes their regulated metal deposition (“RMD”) mode. If you do a lot of pipe welds, the Trailblazer 325 may be a good choice.
After adding leads and other accessories, the Trailblazer 325 is at the high end of the price scale. But as already noted, certain included features will appeal to some and they may be willing to pay extra to get them.

- This one is pricey
The Eagle Plus 10,000 by Lincoln Electric is one of the most commonly seen engine welders in the industry. This generator welder provides 9000 continuous watts for welding or power generation and peak power of 10,500 AC watts for device starts. It’s an unusually high-quality unit, fully powder coated with a completely enclosed engine compartment. The doors are removable for servicing the 23 horsepower Kohler engine and the generator.
The Lincoln Eagle Plus runs multiple processes, including 225 amp DC stick, 200 amp DC TIG, MIG and flux core wire feed welding from 50 amps to 225 amps. It’s also able to do gouging and plasma cutting on up to 3/8-inch thickness of plate steel. Running below its max-rated current output can also run other power tools and small welders off its generator, up to the maximum 9000 running watts AC power.
Lincoln Electric is well-known for rugged, well-built machines made to last for decades. The Eagle Plus engine welder is often seen mounted to truck beds for use by piping and steel crews. Lincoln provides a 20-foot electrode connection and a 15-foot work clamp.
The most significant advantage to engine-driven welders is not being tied to power outlets. You don’t have to search for one every time you need to weld.
Plus, there’s no need to spend money to wire your home or shop with a dedicated 240-volt circuit.
You simply set up the welding leads, fire up the engine, and start welding with an engine-driven welder—no matter where you need to work.
Work Requirements and Welder Choice
As with any type of welder, the work you plan on doing is your main concern. An engine-driven welder is useful, but it may not be your best option.
For example, if you don’t expect to weld material more than 1/4-inch thick, won’t use the welder more than once a month, or you expect to weld a lot of sheet metal, then an inexpensive 120-volt flux core welder might be a better fit.
In an indoor, industrial setting like a factory or commercial construction site where power is readily available, a standard 240-volt welder produces enough welding current to get the job done. Using the available electrical power makes good sense.
Also, in cases where the engine-driven welder would be run in enclosed spaces, it is not appropriate because of the danger posed by engine exhaust.
So, consider the work and site conditions and factor that into your decision when considering which welder works best for you.
An engine-driven welder shines in situations that require high current levels, especially when there are no power outlets available.
Because they make their own power, they can be taken anywhere. Most generate more power than they need. So, you can use the excess capacity to run power tools or other electrical devices.
In general, welder/generators are designed as DC arc welders that use the stick welding process. But some units offer AC welding and an AC power supply for your accessories and appliances.
A 4000-watt engine welder can do a great job running a few power tools. But it isn’t going to have enough power left over to weld with a coworker running a grinder plugged into the same machine. So, make sure the generator can produce the wattage you will need.

Total AC Power Rating
The generator in an engine-driven welder generates AC. Then it’s either fed to AC outlets or converted into DC power for welding, either through an inverter or a transformer.
In some units, the generator powers the outlets and welder at the same time. So, if you plan on welding while your coworker grinds, you will need higher watts.
Total DC Current or Wattage
The welding capability of an engine-driven machine depends on the available DC produced by the welder. A 4000-watt welding generator can produce about 200 amps of current and enough power to stick weld 1/2-inch steel.
With large generator welders, though, the welder cannot use all of the watts produced. Don’t assume high continuous generator watts equals a high welding current. Check the DC wattage or DC amps output to assess the welding power.
Most of these machines are designed for stick welding. But some allow connecting accessories like gas valves, spool guns, or wire feeders for MIG, TIG, and flux core welding.
So, if you need certain features, be sure to buy an engine-driven welder that includes them or that they can be added in the future. You don’t necessarily have to buy all the options right away, but you need a unit that can accept them in the future.
Multiple Welding Processes
Yes, some engine-driven welders include multiple welding processes, and that can be handy. So, look for a welder/generator that includes the welding processes you need.
However, you could run a separate MIG welder, plasma cutter, or TIG welder off the generator. So, remember, the generator portion gives you options. Simply plug in a welder or cutter to the generator that offers the needed process.
For many professional welders, this makes the welders they have collected over the years more useful. They can now use them in the field where there are no power outlets by simply using their engine-driven welder as a stand-alone generator.
Most welder/generators are heavy. That’s just a fact. So, they are usually mounted to trailers or truck beds to transport them.
But there are smaller ones like the Klutch 7500K Arc Welder/Generator that only weigh around 250 lbs. This is about the same as an average 5000-6000 watt generator.
Many 4000-watt engine-driven welders come with wheels and handlebars to make loading, unloading, and moving easier. But this wheelable unit gets you 6000 watts of continuous power and weighs in at a svelte 230 lbs.
The Final Verdict
Because engine-driven welders are often used as dedicated machines by professional welders, we’ve chosen the Lincoln Electric Ranger 250 GXT Multi-Process Welder/Generator as our Pro Selection.
It offers multiple processes, including wire feed and TIG, in addition to the usual stick welding. Plus, there is plenty of generator power to run a separate plasma cutter if you need to break down stock.
With an impressive 10,000 watts of continuous output, a helper can be grinding, drilling, or cutting with electric power tools while you’re working on something else. This lets you get jobs done faster and more professionally.
This Ranger 250 GXT is a well-designed, quality machine that comes with a 3-year warranty. Lincoln also priced this unit competitively compared to other engine welders in the same class. But you still get loads of valuable features. That makes it an easy pick in our book.
