Gas-Powered Welding Generators

Electrode welding from 60 to 200 A and a 6,500 W generator in a single unit, powered by a gasoline engine: for welding and powering an angle grinder in places where no power cord can reach. Two versions available: Timanfaya and Timanfaya-S. 3-year warranty.

What Is a Motorized Welding Machine and Who Is It For?

A portable welding generator is a gasoline-powered engine that drives an alternator designed for welding: it provides the steady direct current required by a welding electrode, as well as a 230-volt output for power tools. It is not a generator to which a welder is plugged in; it is a welding machine with its own power source.

Genergy manufactures a motorized welder in two versions. The Timanfaya, with an electric starter and battery, for those who use it often. And the Timanfaya-S, with manual start, IP67 connectors, and a 30 mA ground fault circuit interrupter (GFCI)—this is the version designed for public works projects and rental companies. Both models are equipped with the same motor SGB460PRO Creta generators, AVR electronic regulation, copper alternator, Typhonic air filter, and a display showing operating hours. If you always weld using a handheld plug, your equipment is different: a MMA inverter welder, lighter and cheaper.

Why do you need it?

People buy portable welding generators for a specific reason: they need to weld, but there's no power. These are the most common ones.

Play

Structural work, rebar, and metalwork on the construction site without a utility connection

Pillars, beams, handrails, and anchors before the job site lighting arrives. A 3.25 mm electrode all day long, with the angle grinder plugged in right next to it. Timanfaya, or Timanfaya-S if the job requires a ground fault circuit interrupter and IP67 outlets.

See Timanfaya →
Field

Fences, gates, farm tools, and irrigation on the farm

Repair the trailer on the plot, weld a post or the pivot arm two kilometers from the barn. Just one tool in the pickup: it welds, and powers the drill and the work light when evening falls.

See Timanfaya →
Maintenance

Mobile Technical Service and In-Home Repairs

Warehouses, farms, wastewater treatment plants, pumping stations: the technician arrives, does some welding, and leaves without asking for an outlet or laying out 50 meters of hose. The electric start with a key is a blessing twenty times a day.

Rental · Public Works

For the rental fleet or the government contract specifications

30 mA residual current device (RCD), IP67-rated outlets, and manual start-up without the battery discharging in storage. This is the Timanfaya-S: the "S" version of the motor-driven generator, based on the same design philosophy as the "S" versions of the generators.

See Timanfaya-S →
Facilities

Solar power, telecommunications, roads, and utility lines

Panel structures at a solar farm, antenna towers on a hill, sections of pipe in a trench. Linear projects, far from everything, where every trip to get power is an hour wasted.

Emergencies

Troubleshoot when the network has also failed

After a storm or a flood, the first thing you need to weld is usually in a place without power. The portable welding generator repairs equipment and, at the same time, provides 6,500 W of power to the sump pump or lighting. If you need to pump water on a large scale, check out our motorized pumps as well.

Can you weld with a standard generator?

That's the question that brings half the people here, and the honest answer is: sometimes, poorly, and at a risk to the generator. Here's what happens.

The electrode requires peak power, not watts. A 160-amp inverter welder “consumes” about 5–6 kW on average, but when striking the arc, it requires much higher peak power for milliseconds. A conventional generator interprets this as a short circuit.
The generator experiences a voltage drop. The regulation doesn't kick in in time, the voltage plummets, the arc goes out or sputters, and the weld comes out porous. And every voltage drop takes a toll on the welder's electronics.
You need to go way overcapacity. The rule of thumb in the trade: double the welder's power, and with AVR. For 160 A, that means a 10–12 kW generator that weighs more and costs more than a portable welding generator.
The portable welding generator solves this right out of the box. Itsalternator is designed for welding: it delivers 60–200 A of regulated current directly, without going through an inverter, and has a separate 230 V outlet for power tools. One machine, two jobs—no conflict.

The power ratings in this section are industry benchmarks, not catalog figures. Genergy. If you already have a generator and an inverter welder, check with us before connecting them: it depends on the model.

Why a Motorized Welding Machine? Genergy

A true 2-in-1

Welding machine and 6,500-watt generator with separate outputs. More than enough power for a grinder, drill, and work light all at once.

The Creta's Engine

SGB460PRO Euro V: the same engine found in the 7,500 W inverter generators from Genergy. Common replacement parts and an engine with thousands of units in service.

Typhonic Filter

A two-stage industrial air filter designed for construction dust and outdoor use. It’s the difference between an engine that lasts and one that chokes in the summer.

AVR Regulation and Copper

Electronic voltage regulation for the 230 V output and a 100% copper alternator with optimized cooling: less heat buildup during long welding sessions.

Screen showing the time

Voltage, frequency, and cumulative operating hours displayed on the screen. To know when it's time for an oil change, and to bill for hours if you rent it out.

Type-Approved S Version

30 mA residual current device and IP67-rated outlets as standard on the Timanfaya-S: exactly what public works specifications or a rental company’s insurance policy require, with no external panel.

How to Choose a Motorized Welding Machine: The 6 Key Factors

The specifications for portable welding machines are very similar across brands. Here are the six figures that distinguish a machine that works for you from one that’s either too much or not enough.

1

Maximum and minimum amperage

The maximum is determined by the thickest electrode (200 A → up to 4 mm). The minimum is just as important, if not more so: 60 A allows for welding thin sheet metal without piercing it. A machine that starts at 90 A is not suitable for auto bodywork or lightweight tubing.

2

Duty Cycle

The percentage of every 10 minutes that you can weld at maximum amperage without stopping due to temperature. A 60% duty cycle at 200 A means 6 minutes of welding and 4 minutes of rest. On the data sheet, this is listed as the “duty cycle”—always ask for it.

3

Actual auxiliary power

The larger number is the maximum; the one that matters is the rated power (6,000 W at Timanfaya). And make sure the 230 V output is separate from the welding output: if they share the same alternator, you can't grind while someone else is welding.

4

Engine and Air Filter

A portable welder spends its days amid construction dust and straw. The air filter has a greater impact on the engine's lifespan than its displacement. And an engine with readily available replacement parts (the SGB460PRO is also used in the Creta) is an engine that can be repaired.

5

Start-up and Protections

Electric with a key if you start it twenty times a day; manual if it’s going to sit in a rental warehouse for months. A 30-mA ground fault circuit interrupter and IP67-rated outlets if you work for the government or insure a fleet.

6

Cables, Wheels, and Who's Responsible

Ground cables and clamps included (with a total usable length of 2 m + 4 m), wheels suitable for the terrain where it will be used, and a technical support service you can call in your country.

Safe Welding in the Field

Six rules to avoid most problems with a portable welder outside the workshop.

Outdoor Motor, Always

It's a gasoline engine: exhaust fumes must be vented outside enclosed spaces, trenches, and pits. If you're welding inside, the machine stays outside and only the cables are brought in.

Mass near the cord

Place the ground clamp as close as possible to the welding spot and on clean metal. If the ground is too far away or on painted metal, the arc becomes unstable, and you'll blame the machine.

Refuel when the vehicle is cold and stationary

Never use it while the engine is hot or with the arc lit nearby. Gasoline and sparks from the grinder don't mix, and out in the field there's no fire extinguisher on hand unless you bring one: so bring one.

Cables without makeshift splices

Extending welding cables with homemade splices causes the joints to overheat and reduces the actual amperage at the clamp. If you need more length, use cables with the proper gauge and threaded connectors.

Drive slowly between the curbs; do not turn off the engine

Turning the engine off and on every five minutes puts a strain on the battery and the starter motor. Between rows, let it idle; turn it off when the row is finished.

Welding Equipment

A welding helmet with a filter rated for the appropriate amperage, welding gloves, a fire-resistant apron or sleeve, and safety footwear. And at 200 A, hearing protection is essential: the arc and the grinder easily exceed the ear’s tolerance level.

General guidelines for use; specific safety procedures for each job are determined by the job site risk assessment and the equipment manual.

Frequently Asked Questions About Motorized Welders

What is a motorized welder?

An electrode welding machine equipped with its own gasoline engine and an alternator designed for welding, so it does not need to be connected to the power grid. Most models, such as the Timanfaya, include a 230-volt outlet to power tools: a welder and a generator in the same chassis.

What are portable welding generators, and how do they differ from a generator?

A generator produces 230-volt alternating current for powering devices. A motor-driven welder also produces the regulated current ranging from 60 to 200 A that an electrode needs, with an alternator designed to withstand the peaks of the arc. That is why a motor-driven welder welds well, while a standard generator generally does not.

What is the best brand of welders?

When choosing a portable welder, rather than focusing on the brand, consider these four factors: the amperage range (200 A is sufficient for electrodes up to 4 mm), the actual auxiliary power at 230 V (6,500 W allows you to run one tool at a time), the motor and its air filter (dust can damage motors), and who will provide service and replacement parts afterward. Genergy It comes with a 3-year warranty and technical support in Spain; compare that to what you have on hand.

How much does a portable welder cost?

It depends on the amperage, auxiliary power, and type of starter: the Timanfaya has an electric starter, and the Timanfaya-S adds a 30 mA ground fault circuit interrupter and IP67-rated outlets. We’ll put together a package for you with the cables and accessories you need—just fill out the contact form.

Can you weld with a standard generator?

Only with a generator equipped with an AVR that has roughly twice the power of the welder—and even then, there’s a risk of an unstable arc and damage to the electronics. For 160 A, we’re talking about a 10–12 kW generator. A motorcycle-powered welder solves the problem right out of the box; this is explained step by step above.

What electrode can I use with 200 A?

Up to 4 mm in diameter with some leeway, which is standard for structural steel and thick sheet metal. The 5-mm ones draw more than 200 A and are excluded. The 2.5- and 3.25-mm ones, which are most commonly used in locksmithing and construction, fall within the optimal range.

Can I use the grinder while someone else is welding?

Yes. The 230 V output (6,500 W maximum, 6,000 W rated) is independent of the welding output. An angle grinder, a drill, and a work light can all run at the same time without affecting the arc. It’s a true “2-in-1”: two separate power outputs, not a single output split between them.

What is the difference between Timanfaya and Timanfaya-S?

The S model features a manual start (no battery to drain while in storage), a 30 mA differential, and IP67-rated outlets. It is the version designed for rental companies and public works projects. The welding unit, motor, and generator are identical.

Can it be used for TIG or MIG welding?

The Timanfaya uses coated electrode (MMA) welding. For TIG or MIG, you need specific equipment; if you have a power source, check out the MMA/TIG inverter welder. How this equipment works: how an inverter welder works.

How many hours does a tank last?

It depends on how long you keep the arc on: welding at 200 A uses much more power than letting the motor idle between weld beads. The exact tank capacity and runtime are listed in the specifications for each version.

What kind of maintenance does it need?

The same as for any four-stroke gasoline engine: oil based on the hours shown on the display, a clean Typhonic air filter (it’s a two-stage filter that holds more dust), a spark plug, and fresh gasoline if it’s going to be idle for months. The replacement parts are the same as those for Creta generators.

Is it noisy?

This is a construction tool with an exposed gasoline engine. If noise is your top priority, this isn't the machine for you; however, while welding, the arc and the angle grinder make more noise than the engine. The exact noise level is listed in the product specifications.

Should you use "Timanfaya" or "Timanfaya-S" for your project?

Tell us which electrode you use, how many hours a day, and whether the machine is for a fleet or a public works project, and we'll respond via the contact form with the model, cables, and price. 3-year warranty and technical service in Spain.

I recently purchased a Limited 7000 generator. I contacted the company by email to ask a few questions, and they responded immediately. Plus, they’re going to replace the industrial outlet adapter in a couple of days. GREAT AFTER-SALES SERVICE—for once, what they say is true; that’s what I call service. As for the generator, it looks well-built and high-quality, starts right up, and the noise level is about what you’d expect from a gasoline-powered generator—it’s a good machine. For now, I’m giving Genergy 5 stars.

I bought the 3000 diesel generator. They tested it at the factory before shipping it to me and delivered it with oil already in it and ready to use—even though they didn’t have to, since with large retailers, they don’t even bother to open the box for you to inspect it. Once tested, it works very well, and I have no complaints. The customer service is excellent. I called several times to get more information—and, by the way, to make sure it wasn’t one of those scams that are so common in online sales these days—and I can assure you that this is a trustworthy company from which I’ll make future purchases. Thank you very much for everything.

Definitely a trustworthy company. I had a minor issue with a generator, and they resolved it within 24 hours. They responded to my email incredibly quickly and provided a fast, effective solution—the kind you’d expect from a mature, well-established team. Their communication was direct, transparent, and straightforward, with no evasive tactics or automated replies that lead nowhere. By the way, the generator is a Genergy 5000, and it works like a charm—well-designed, compact, and reliable. I use it almost exclusively to power a 1.5 HP well pump. It’s definitely a great choice, and I highly recommend it.
