Diesel Engine driven welder - Yanmar L70N Engine -  Permanent magnet alternator - Single-phase generation 3.3kVA - Max welding current: 200A

The engine-driven welder Magic Weld 200 YD is a lightweight, professional machine with electronic control of the welding current capable of delivering up to 200 A with a duty cycle of 60%.

The Magic Weld 200 YD combines 3 qualities: compact and light weight (only 72 Kg); chopper system; an inverter capable of generating 3.3 kVA of auxiliary power. Equipped with a YANMAR L70N diesel engine and a permanent magnet alternator, it can function simultaneously as a welder and generator.

The Magic Weld 200 YD 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".

Its weight and performance make it a machine suitable for maintenance and mobile welding.

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 .
