General Characteristics
The
ASKAYNAK Inverter 201-TIG PFC
is an inverter type TIG-MMA welding machine manufactured
using the latest PFC (Power Factor Correction) technology. Starting from the 1980s, the welding
machines in the market have been sized down thanks to the inverter arc welding machines appearing
in the market while increasing the efficiency. However, many semi-conductor devices (i.e. diodes,
transistors, IGBTs etc.) used in such machines chop the mains voltage for use, hence distorting the
wave-form of the mains supply that result in harmonic waves. The total current drawn by the machine
from the mains (RMS) includes all such harmonic components. With the PFC technology, active
PWM technique is used for filtering out the harmonic components drawn from the mains although
they are not used by the machine.
The
Askaynak Inverter 201-TIG PFC
welding machine draws maximum 33A of current from the
mains instead of 44A, thus increasing the energy efficiency. With this property, the
Askaynak
Inverter 201-TIG PFC
reduces the amount of energy used, hence the operating costs, for the
consumers while reducing the pollution in the transmission and distribution lines, contributing to the
sustainable development through the reduction of power losses.
The
Askaynak Inverter 201-TIG PFC
is a shielded electrode and TIG welding machines operates in
the CC characteristic and features igniting with HF (high frequency), down slope, up slope, hot start
and short circuit protection properties:
Operating principle:
The 220 VAC mains power is converted in to 380 VDC by the PFC. The half
bridge inverter structure converts the DC voltage ib to AC voltage again, which is reduced by a
transformer. The reduced voltage rectified again, filtered and sent to the output.
