Mosa TS 255 EVO Diesel Powered Generator – Water Cooled

The Mosa TS EVO 255 is a part of Mosa’s new generation of Engine Driven Welders. The TS EVO 255 is diesel powered offering 110, 230 and 400V socket outputs, ideal for site work.


Fitted with a large 38 litre fuel tank and a fuel level sensor for long lasting running time (approx. 11 h) while welding, and alerts the user when fuel is low.

This generator is the peak of its kind, for efficiency and reliability. Water cooled temperature regulation for the highest possible duty cycle and stability. Compatible for TIG and Stick (MMA) welding with an open circuit voltage of 66 Vcc (68 Vcc peak) and benefits from an electronic starter. Mosa has used a completely new canopy design for this generator, making it sleek and safe. Simple openings in the body for easy maintenance and replacement of air, oil and fuel filters, as well as external plugs for draining oil and water.

Welding Output of between 20 – 250 A (STICK 200A @ 28V/ 100%  | TIG 250A @ 20V / 100%).

Output power of between 10.3 kW (14 hp) and 9.3 (12.6 hp) with a fuel consumption of between 3.9 litres per hour (110% on stand-by) and 1.9 litres per hour (50%).

Thanks to the forklift pockets fitted to the base, this generator is easy to manoeuvre around a workshop / warehouse space, as well as a central lifting eye for easy and safe movement by use of a crane.

Engine functionality controlled via the new, handy and intuitive IntelliNano digital engine management control for maximum efficiency and setting tracking through any external conditions.

This generator meets the latest Stage 5 Diesel Emissions Standards.
