The Mosa TS 300 KSX/EL diesel welder generator offers an AC generator output of 10 kVA single and 3 phase power.  The TS 300 provides up to a 300 amp DC welding output using 2-6mm diameter electrodes. It has a dual range function and an open circuit voltage of 70V. Incorporated in the Mosa TS 300 KSX model is a 12V battery, a battery charge indicator and the machine benefits from an electric start.

An advantage of this generator welder is its’ diesel, Kholer engine which runs to a high specification and is very efficient with a fuel consumption of 2.5 litres per hour. The engine output is 14kw (19 hp) and has the capacity to generate an accessible speed of 3000 rpm.

With a weight of 370kg, the Mosa TS 300 KSX / EL has super silenced canopies and is EEC noise compliant.

Equipped with all the usual TS series features including Arc Force control, stepless electronic welding control, auto idle control and a remote control option.

Suitable for a wide range of uses including mobile welding, site fabrication, maintenance and pipeline construction.

Central to the success of Mosa Welder Generators is their asynchronous welding alternator.  This brushless alternator designed and manufactured in house offers excellent welding characteristics and simultaneous AC auxiliary power and requires no maintenance as there are no brushes to wear and the solid rotor has no windings.


TBWS are able to access an impressive back catalogue of spares, parts and accessories for the Mosa range.  This, coupled with the best build quality of Mosa machines, makes for machines that are built to last through servicing and repairs if required.
