Diesel Engine driven welder - KOHLER KD 477-2 Engine -  Three-phase asyncronous alternator  - Three-phase generation 10 kVA - Single-phase generation 5 kVA - Max welding current: 350A

The engine-driven welder CS 350 KSX CC/CV is a professional machine with electronic control of the welding current capable of delivering up to 350 A with a duty cycle of 60%.

Incorporating Chopper System (high frequency 30 kHz), which allows for a more stable arc when welding and superior finished weld quality.
Equipped with a KOHLER KD 477.2 diesel engine and an asynchronous alternator, it can be used simultaneously as a welder and as a three-phase and single-phase electrical generator up to 10 kVA.

Model CS 350 KSX CC/CV  also features auto idle economizer which introduces the concept of "power on demand", allowing both fuel savings and reduced engine wear. The CT 350 KSX is able to weld any kind of electrode (rutile, basic, cellulose) up to 6 mm and takes full advantage of the engine's power output thanks to a technology developed by MOSA known as "Power Optimizer".

Also available is an optional remote welding control allowing welding current adjustment up to 20 metres from the welder. This is a super silent engine-driven welder with compact canopy, specifically designed to minimize sound emissions.

It is also possible to select welding output in CC or CV mode.
In CC (constant current) mode, you can choose between a characteristic with adjustable arc force, suitable for electrode welding and TIG welding (scratch start).
The CV (constant voltage) mode is suitable for WIRE WELDING (solid or flux-cored) using the optional Mosa Wire Feed Unit WF4.

Power Optimizer

sample powersafe Some welding machines incorporate the "Power Optimizer" function , designed and patented by MOSA.

This is a specific control technique aimed at preventing the engine overload when working near to its power limit.

With the " Power Optimizer " it is possible to ensure stable and optimal operation in all the welding conditions, exploiting the full power of the engine .
