LHE 200/300/400 DC RECTIFIERS
 
 

The LHE 200/300/400 rectifiers are robustly designed and are controlled by a movable core which makes them reliable and easy to maintain.
A wide range of electrode types can be welded and, as a result of the high duty cycle, this makes them ideal for industry, farmers and repair shops. The three-phase mains supply keeps the fuse size low.
These LHE rectifiers are overload-protected by a thermal switch with an indication lamp. They are made mobile by a built-on undercarriage.
No CE marking.

Delivery includes
5 m of mains cable.
