1) SAFETY
This manual has the purpose to guide experienced people about installation, operation and maintenance
for LHJ 425 rectifier.
DO NOT allow non-qualified personnel to install, operate or repair this equipment. Read and understand all
information in this manual.
Remember that:

¡
As with any machine or electric equipment must be unplugged from the energy source before any
preventive or corrective maintenance should be done.
In order to carry out any internal measures or interventions that require the equipment to be on make sure:
1) the equipment is correctly grounded;
2) the working area is dry;
3) all the internal and external electric connections are correctly tightened.
On the other hand, the technician that measures or intervenes must be appropriately protected against
electric shock, and must use adequate devices and tools for work on electric circuits.
Conditions 1, 2 and 3 above equally apply to the welding work. Besides these conditions make sure the
electrode-holder is in perfect conditions of isolation and that all-electrical contacts existing in the feed and
welding circuits are safely tight. The welder must always be appropriately protected against the effects of
electrical arc, electric shocks and welding spatters.
