Product Description

Experience unparalleled versatility and power with the GRETECH JLY-4000IW, a premium Multi-Fuel Generator specifically designed for professional off-grid use. This robust unit seamlessly combines high-output power generation with professional-grade welding capabilities, ensuring you have the necessary power for any demanding job site. Equipped with innovative Tri-Fuel Technology, it offers the ultimate convenience by allowing operators to run the machine on LPG, Natural Gas (CNG), or standard Petrol.

Core Power and Welding Capabilities This hybrid machine is engineered to deliver stable, clean energy alongside heavy-duty welding performance. Its Pure Sine Wave Output guarantees that even your most sensitive electrical devices and diagnostic tools remain perfectly safe during operation.

  • Inverter Welding Output: Delivers a stable 160 A welding current with a flawless 100% duty cycle at 160 A.
  • Electrode Capacity: Supports a maximum electrode diameter of Ø 4.0 mm, which can be impressively scaled up to Ø 8.0 mm when units are connected in parallel.
  • Max Power Output: Achieves a maximum power of 4200 W (3800 W rated) on LPG/Petrol and 3780 W (3420 W rated) on Natural Gas, providing a reliable 230 V single-phase supply.

Engine and Build Specifications Durability and consistent performance are at the heart of this generator’s mechanical design. It is driven by a highly reliable JL172F / 7.5 HP / OHV engine featuring a 223 cc displacement to keep your intense operations running smoothly without stalling.

  • Fuel Management: Includes a 7.5 L capacity fuel tank complete with a built-in level indicator for easy monitoring.
  • Safety & Protection: Built to rigorous industrial standards featuring Insulation Class H and Protection Class IP21.
  • Hybrid Efficiency: The prominent LPG, CNG, and GAS hybrid integration means you can easily adapt to whatever fuel source is most cost-effective or available in your location.

In summary, this hybrid inverter welding unit stands out as an elite Multi-Fuel Generator that tackles both primary power supply and industrial welding tasks simultaneously. Its unique combination of a 100% duty-cycle welding system, clean pure sine wave power, and robust tri-fuel adaptability makes it an indispensable, future-proof asset for modern professionals.

GRETECH hybrid generators powered by LPG will have the same power output with the gasoline, as our mixing valve of our hybrid generators automatically adjusts air intake and LPG/NG to air ratio, allowing the generators to output same power as do gasoline generators. More importantly, when the LPG/NG generators are in use, their engines rotate steadily, allowing stable power output.

GRETECH LPG/NG generators’ expected life expectancy are more than 2 times longer than that of gasoline generators.

Leakage-Proof: GRETECH hybrid generators’ mixing valve is uniquely designed so that even if the gas regulator or switch is kept on, the gas will never leak.

Easy Start: GRETECH hybrid generators, no matter brand new or not being used in a while, can always be immediately turned on by pulling the recoil rope up to 3 times.

Cost-effective: The fuel consumption costs of GRETECH, LPG (0.36 kg/kw.h) and NG (0.35 m³/kw.h) generators are much lower than gasoline generators (0.5 L/kw.h).

Compatible with source pressure ranging from 2.0 to 6.0 kPa (0.29-0.87PSI), our generators are suitable in almost all environments, including at home.

GRETECH generators use perfect amount of LPG/NG to meet output power, so the gas is always burnt completely, producing clean emissions.

The noise of GRETECH generators is 5dB quieter, as own patented muffler.
