firmly fixed to its terminals, also make sure that the connections in the piece to be weld or in the working
station and in the "Negative" terminal of the set are well fixed.
Any total length (which should be the smallets possible) and any welding current used, the work clamp
cable part should correspond to the maximum current of the LHI RECTIFIER used to supply the duty cycle
of 60%.
The thermal welding circuit causes a drop in the voltage which added to the internal natural drop in the
Rectifier itself, reducing the voltage arc and the maximum current available making the arc unstable.
7) OPERATION
After having the LHI RECTIFIER connected to the main power supply, the electrode holder cable and the
work clamp
cable connected:
1)
Set the ON/OFF switch to the ON position. The exaustor engine starts to run creating a air flux needed to
cool the machine.
2)
Pre-define the welding current throught the potentiometer or the remote control. The potentiometer
rotation clockwise increases the current value, and the rotation anti-clockwise decreases the current
value.
P.S.: The parameter welding values depends, basically, on the material and
the diameter of electrode used, the thickness to be weld and the welding
position.
3) Open the arc, and if needed re-adjust the current.
8) MAINTENANCE
8.1) Recomendations
The LHI Rectifier requires little maintenance in normal environment and opperation conditions. It is
sufficient to blow it dry clean using dry compressed air free from oil
After cleaning the equipment with blow dry air, check that the electric connections and components are
properly fixed.
Check for possible faults in the wire isolations or electric cables, including the welding cable and any others
and if any of them is faulty substitute it.
8.2) Repair
In order to ensure the perfect functioning and performance of a ESAB equipment, use only original parts
supplied by ESAB PLC or approved by them.
All guarantee undertakings from the supplier cease to apply if the customer uses non-original or non -
approved parts when replacing any of them.
Spare parts can be obtained from the ESAB Authorized Services or from its Sales Distributors listed on the
last page of this Manual. Always inform the Equipment Model and Serial Number.
