Why Choose a Shindaiwa Welder Generator?

1. Industry-leading 3-year warranty. Shindaiwa is the only company in the UK to offer a full 3-year warranty on all welder and generator products, so you can buy with confidence.
2. Try before you buy. Every model is available for a free, no-obligation demo on your own site, so you can test performance on real work before you commit.
3. Fully compliant. Every Shindaiwa welder generator is manufactured in Japan and complies with current CE, UKCA, EMC, Stage V emissions and noise legislation.
4. Support that keeps you working. A full stock of spare parts and accessories, a 24/7 service team and depots in Wolverhampton and Perth mean problems are put right quickly and downtime is kept to a minimum.
5. Low noise, low fuel use. Our machines are among the quietest and most fuel-efficient in their class, making them well suited to urban sites, night work and long shifts.

Petrol vs Diesel Welder Generators: Which is Right for You?

The right choice depends on how long the machine will run each day, the size of the work and how often it moves between sites.

• Petrol welder generators are lighter, quieter and easier to start, which suits shorter jobs, light industrial work and teams who need maximum portability. See our petrol welder generator.
• Diesel welder generators are more fuel-efficient, more rugged and more cost-effective for long shifts and heavy-duty use. They suit large construction projects, offshore work and demanding industrial applications. See our diesel welder generators.

As a rule, if the machine will run for most of the working day or you need more than 200 amps, choose diesel.

Frequently Asked Questions

What is a welder generator used for?
A welder generator is a dual-purpose machine that combines power generation with welding capabilities. It’s commonly used on construction sites, in workshops, and at remote locations where both electricity and welding are required. This makes it an efficient solution, removing the need for separate equipment.

What is the difference between petrol and diesel welder generators?
The main difference lies in fuel type and performance. Petrol welder generators are generally lighter, easier to start, and suitable for short-term or light use. Diesel welder generators are more fuel-efficient, durable, and designed for heavy-duty or long-duration applications, making them the preferred choice for industrial worksites.

Are welder generators portable?
Yes, many welder generators are designed to be portable. Compact models are easy to transport and often fitted with wheels or lifting points. This portability makes them ideal for jobs that require moving between different work areas, such as repairs, construction, and remote fieldwork.

Are Shindaiwa welder generators compliant with UK/EU regulations?
Yes. All models meet CE, UKCA, EMC, Stage 5 emissions, and noise regulations. They are built to perform reliably in harsh industrial and construction environments and come with a full 3-year UK warranty.

How long can a welder generator run?
Runtime depends on the fuel type and workload. Our petrol ECO 165-2 can run for up to 12 hours from a single tank in Eco mode, which electronically adjusts engine speed to match the load. Our diesel models, the ECO 200, ECO 300 and ECO 400, are fitted with larger fuel tanks and are designed for extended, continuous operation on heavy-duty sites, making them ideal for long shifts where refuelling stops need to be kept to a minimum.
