ECO 165-2 Petrol Welder Generator

High-Performance, Lightweight, and Fuel-Efficient Welding Power

The Shindaiwa ECO 165-2 Petrol Welder Generator is a Stage V compliant, portable welding power solution designed for professional use across the UK. Delivering 50–165 Amps of smooth DC welding output and 3.2kVA of auxiliary AC power, this compact unit is perfect for construction sites, mobile fabrication, offshore maintenance, and remote repair work.

Powered by a reliable Yamaha MZ300 petrol engine, the ECO 165-2 petrol welder combines fuel efficiency, mobility, and all-day runtime with the backing of Shindaiwa’s industry-leading 3-year warranty.

Why Choose a Petrol Welder Generator?

For contractors, hire fleets and mobile fabricators, a petrol welder generator offers three practical advantages. First, weight: at the lowest weight in its class on the UK market, the ECO 165-2 can be lifted into a van or moved around site without mechanical handling. Second, simplicity: petrol engines start easily in cold conditions and suit intermittent, stop-start working patterns. Third, refuelling: petrol is available on every forecourt, which matters for mobile repair work far from a diesel bowser.

The ECO 165-2 pairs these advantages with genuinely professional output. Its Yamaha MZ300 engine drives 50 to 165 Amps of smooth DC welding current with digital current setting accurate to within 1 Amp, while the 3.2kVA 110V auxiliary supply runs power tools up to and including 9-inch grinders at the same time as you weld.

The impact-resistant polycarbonate canopy shrugs off the daily knocks of mobile fabrication work while keeping weight to a minimum. In Eco mode, engine speed is electronically controlled to match the load, stretching a single tank of fuel to up to 12 hours of operation.

Low noise levels keep the unit compliant on residential and urban sites, and Stage V certification means it meets the latest UK and EU emissions standards. Like every Shindaiwa machine, it is manufactured in Japan and backed by our industry-leading 3-year warranty.

Frequently Asked Questions

Can I run power tools while welding?
Yes. The 3.2kVA 110V auxiliary output can be used simultaneously with welding, comfortably powering grinders, drills and site lighting.

How long does it run on one tank?
Up to 12 hours in Eco mode, which electronically matches engine speed to the load to minimise fuel consumption and noise.

Is it road-legal to transport?
The ECO 165-2 is a compact, portable unit designed to travel in a van or pickup rather than on a trailer, making it the easiest machine in our range to move between jobs.

What warranty does it come with?
Every Shindaiwa welder generator, including the ECO 165-2, is covered by our 3-year warranty, the only full 3-year warranty on welder generators in the UK.

Should I choose petrol or diesel?
Choose the petrol ECO 165-2 for portability, lighter workloads and frequent moves between sites. For continuous heavy-duty use, higher amperage or long unattended runtimes, see our diesel ECO 200, ECO 300 and ECO 400 models.
