| 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.
