WARNING
Welding and cutting is dangerous to the operator, people in or near the working area, and
the surrounding, if the equipment is not correctly operated. Therefore, the performance of
welding/cutting must only be under the strict and comprehensive observance of all
relevant safety regulations. Please read and understand this instruction manual carefully
before the installation and operation.
• The switching of function modes is possibly damaging to the
equipment, while the welding operation is performed.
• Do disconnect the electrode-holder cable with the equipment,
before the performance of welding.
• A safety switch is necessary to prevent the equipment from
electric-leakage.
• Welding tools should be of high quality.
• Operators should be qualified.
Electric Shoc : It may be fatal
• connect the earth cable according to standard regulation.
• Avoid all contact with live components of the
welding circuit, electrodes and wires with bare hands. It is
necessary for the operator to wear dry welding gloves while he
performs the welding task.
• The operator should keep the working piece insulating from
himself/herself.
Smo e and Gas generated wile welding or cutting:
harmful to people’s health.
• Avoid of breathing the smoke and gas of welding or cutting.
• Keep the working area in good ventilation.
Arc light-emission: harmful to people’s eyes and s in
• Wear the welding helmet, anti-radiation glass and work
clothes while the welding operation is performed.
• Measures also should be taken to protect people in or
near the working area.
Fire hazard
• The welding splash may cause fire, thus remove flammable
material away from the working place.
• Have a fire extinguisher nearby, and have a train fire person
ready to use it.
Noise: Possibly harmful to peoples’ hearing.
• Surface noise is generated while welding/cutting, the
hearing aids is necessary in some cases.
Machine Fault:
• Consult this instruction manual.
• Contact your local dealer or supplier for further advice.

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
0%. 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 00/WS
400/WSM 00/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.

INSTALLTION & OPERATION
It is important to note that any extension of mains cables or torch cables will
possibly affect the welding performance of this welding equipment, due to the fact
that the resistance of the cable will reduce input voltage, which is decided by the
length of the cable. The assembled length of main cables and torch cables is
recommended.
