The engine-driven welder CS 230 YSX CC/CV is a Constant Current/Constant Voltage professional machine with electronic control of the welding current capable of delivering up to 210 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 Yanmar L 100 N engine and an asynchronous alternator, it can be used simultaneously as a welder or as a three-phase and single-phase electrical generator up to 6 kVA.

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.

The CS 230 YSX CC/CV is able to weld any kind of electrode (rutile, basic, cellulose) up to 4 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 design specifically designed to minimize sound emissions.

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