․ 

Connect  the  gas  hose  to  the  gas  input  terminal.

 

․ 

If  you  want  to  connect  the  water  cooling  unit,  connect  the 

water  hose  to  WATER  IN  terminal.

※  Input  voltage  selection

․ 

Remove  the  cover  of  input  voltage  selection  plate.

․ 

Position  the  copper  bars  for  the  voltage  would  be  used

․ 

For  380V  and  440V  input,  position  the  switch  for  the  voltage  would  be 

used  which  is  inside  welder  after  removing  top  cover.

220V

380V

440V

●  Output  Connection  (Front  of  the  machine)

 

․ 

Connect  the  work  cable  (which  is  connected  to  the  work  clamp)  to  the 

METAL  terminal.

 

․ 

To  connect  the  TIG  torch,  connect  a  electrode  cable  to  the 

TORCH  terminal  and  a  torch  switch                     

    connector  to  the  torch  switch  receptacle  and  a  gas  connector  to  the  output  gas  receptacle.

 

․ 

If  you  want  to  connect  the  remote  controller,  connect  the  connector  of  remote  controller  to  REMOTE                 

    CONTROL  terminal.

 

․ 

If  the  water  cooling  unit  is  installed,  connect  the  water  input  hose  of  water  cooled  torch  to  WATER  OUT         

    terminal  of  welder.
