Magnetic fields affect cardiac pacemaker.
Pacemaker users should be away from the welding spot before
medical consultation.
Moving parts may lead to personal injury.
Keep yourself away from moving parts such as fan.
All doors, panels, covers and other protective devices should be
closed during operation.
Please seek professional help when encountering machine failure.
Consult the relevant contents of this manual if you encounter any
difficulties in installation and operation.
Contact the service center of your supplier to seek professional help
if you still can not fully understand after reading the manual or still
can not solve the problem according to the manual.
2. GENERAL DESCRIPTION
This welding machine is manufactured with advanced inverter technology. With PWM technology and power
MOSFET, it converts the DC voltage, which is rectified from 50Hz/60Hz input AC voltage to 100KHz AC
high voltage. Then the voltage is dropped and rectified. For adopting switch power supply inverter
technology, the machine is much smaller and lighter.
TIG welding function is available on TIG160S, TIG160SII and TIG200S,TIG200SII.
MMA and TIG welding functions are available on TIG180A, TIG200A, TIG300 and TIG400.
TIG160SⅡ, TIG200SⅡ, TIG180PⅡ, TIG180AⅡ and TIG200AⅡ are models of new products with plastic
enclosure. The enclosure is made of non-flammable ABS material. Compared to the machines of metal
enclosure, it has more advantages, such as beautiful appearance, excellent insulation, waterproof,
anti-static and anti-corrosion.
In MMA welding, the external characteristic of the machine is constant current with arc force control.
When the arc voltage is normal, the welding current does not vary with the arc length to ensuring stable
welding and elastic arc. When the arc length is overly short and the arc voltage is overly low, the
current would increases correspondingly to make the arc length recover automatically. And this can
ensure stable arc and adjustable arc force. When the arc voltage is too low to maintain arc, the external
characteristic of the machine turns to drooping to avoid producing spatters due to the high current
when short-circuited.
In TIG welding, the external characteristic of the machine is constant current. The welding current
is very stable, and does not vary with the arc length.
