GENERAL DESCRIPTION
These welding machines are manufactured with advanced inverter technology.
With power MOSFET and PWM technology, the inverter converts DC voltage,
which is rectified from mains input AC voltage, to high (100 KHz) frequency AC
voltage; subsequently, the voltage is transformed and rectified to give a smooth,
stable D.C. output. Working at 100 KHz requires a much smaller main
transformer and results in a lighter weight inverter welder, with an increased
duty cycle. The high frequency oscillation, which enables the output of high
frequency DC, is employed in the arc-starting system. The features of this
product are as follows: stable current, reliable, completely portable, efficient
and low noise output.
The features of the MMA series are: efficiency, energy saving, portability,
excellent dynamic characteristics and stable arc, relatively low no-load voltage,
the ability to meet a wide variety welding requirements.
The cases of the EasyArc 200 model are made from a high impact flame
resistant engineering plastics material. This results in a more attractive, durable
and water resistant machine.
Guarantee of maintenance for main power source is 12 months, excluding
cables, guns, torches and accessory items.
During the guarantee maintenance period, all maintenance is free of charge, but
does not include deliberated damage, or damage caused by misuse of this
welding equipment. Only qualified technicians are authorized to carry out repairs
of this welding equipment in the case of machine breakdown.
