General Description - Hong Kong Easyweld Easytig 160S Operation Manual

GENERAL DESCRIPTION

This welding machine is manufactured with advanced inverter technology. With high-power
component MOSFETS and by adopting PWM technology, the inverter convert the DC voltage, which
is rectified from input AC voltage, to high 100KHz frequency AC voltage; as a consequence, the
voltage is transformed and rectified. Therefore, it result the much more small-sized of the main
transformer and lighter in weight of the inverter welder, which rates the performance of welding 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 output,
reliable, completely portable, efficient and low noise generated while welding is performed.
-TIG welding is available for EasyTig 160S/200S.
Both MMA and TIG are welding are available for EasyTig 180A/200A/200ADS/200P and WS 300/WS
400/WSM 300/WSM 400.
TIG 160S, TIG 200S, TIG 180A, TIG 200A and TIG 200ADS are models of registered design plastic
products, the cover of which are made of anti-combustible ABS material. It possesses more
advantages compared to machines of iron case, such as beautiful design, excellent insulation, and
waterproof.
During the performance of MMA welding, this welding machine is featured with the stability of
output, and the availability of arc force modulation. In case of normal arc input voltage, the
stability of welding current output is not frustrated with variation of arc length therefore it results in
stable performance of welding operation, of which the arc is of elasticity. In case of unavailable
length of arc and low input voltage, welding output current increases while arc voltage decreases,
as a consequence, the length of arc, which is not sufficient, will automatically compensate and the
modulation of arc force is accessible. In case that the input arc voltage is too low to maintain arc,
the output of this welding equipment descends steeply which avoid the splash generated due to
over current input. During the performance of TIG welding, this welding equipment is featured with
the stability of output current and that the welding current output does not vary with variation of
the length of arc. In case of short circuit of electrode, the voltage automatically decreases to OV,
which limits the impairment of electrode and pollution to environment.
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 welding equipment.
Only qualified technician are authorized to carry out the repairs task of this welding machine in
case of machine fault.
