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 YDE 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 YDE combines 3 qualities: compact and light weight (only 91 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 and also features electric start.

The presence of an auto idle economizer introduces the concept of "power on demand", allowing both fuel savings and reduced engine wear.
The Magic Weld 200 YDE 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 .
