TECHNICAL INFORMATION
1. TECHNICAL INFORMATIONS
1.1 GENERAL EXPLANATIONS
●
This cutting machine is manufactured with advanced inverter technology. With high-power component IGBT and
by adopting PWM technology.The inverter convert the DC voltage, which is rectified from input AC voltage, to
high 20KHz frequency AC voltage. As a consequence, the voltage is transformed and rectified. Therefore, it results
the much more small-sized of the power source and lighter in weight of the inverter cutting machine, which rates the
performance of cutting by 30%. The high frequency oscillation, which enables the output of the high frequency DC,
is employed in the arc-starting system. The features of this product are as following: stable the cutting current
output , reliable, completely portable, efficient and low noise generated while cutting is performed.
●
Cutting Process is available for
LGK-80S
.
●
During the performance of cutting, this cutting equipment is featured with the stability of current output and that
the cutting current output does not vary with variation of the length of arc.
●
Guarantee of maintenance for main engine is one year, excluding other spare parts.
●
During the guarantee maintenance period, all maintenance is free of charge, excluding the deliberated damage to
this cutting equipment.
●
Only qualified technician are authorized to carry out the repairs task of this cutting machine in case of machine
fault.
