PROCESS
LHJ 425 and LHJ 750 are welding rectifiers for
welding and fabrication. They have good welding
characteristics and a wide current range, LHJ 425
> 55-425 A and LHJ 750 > 80- 750 A, which
permits welding with a large number of different
types of electrode including basic, with diameters
of 2.0 - 6.0 mm
For mobility in the workshop the rectifier LHJ
425/750 is delivered with rubber wheels and
handle for easy maneuverability. There are two
lifting hooks provided on the top of the rectifiers
for lifting and shifting
The rectifier has an option to fix ESAB digital V/A
meter for showing the welding voltage and
current
They are a fan cooled three phase rectifier
connected to a three phase power
The welding current is continuously adjustable
within the range by means of a trouble free hand
crank at the front panel controlling a movable
leakage core
The rectifier housing is made of power coated
steel sheet designed for both indoor and outdoor
usage under all weather conditions
