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.
