higher  frequency  to  the  peak  pulsed  current  with  lower 
frequency,  some  special  welding  requirements  can  be  met. 
Complicated complex waveform DC pulsed welding can be 
obtained  by  selecting  the  operation  mode  18/19  or  self-
programming in pulsed welding mode. A typical waveform of 
complex waveform DC pulsed welding (operation mode 18) 
is showed in the above figure, in which, Ib and Ip stand for 
the  base  current  and  peak  current  in  pulsed  welding  mode 
respectively.  Id  ‘s  value  is  equal  to  that  of  the  pilot  arc 
current, but it has no sense of pilot arc current, and it can be 
considered  as  secondary  base  current.  T2  stands  for  the 
period of the secondary pulse (LF), and here in this example 
T2  is  200ms.  In  operation  mode  19,  the  period  of  the 
secondary  pulse  (LF)  can  be  changed  at  any  moment  by 
adjusting the upslope time.

TIG operation mode

20  TIG  operation  modes  are  available  for  this  machine,  in 
which 0-15 cannot be amended by users, and 16-19 can be 
amended.  If  you  want  to  amend  the  TIG  operation  modes, 
please  refer  to  the  appendix  Programming  Guide  for  Users 
(TIG mode).
TIG operation mode should be selected according to users’ 
technical  requirements.  All  the  20  TIG  operation  modes  for 
this  machine  are  listed  in  the  table  TIG  operation  modes 
below.

Follow mode:

① 

Push  the  torch  trigger: 

arc  is  ignited  and  current 
rises to the pre-set value.

② 

Release it: arc stops.

1T/Spot welding mode:

① 

Push  the  torch  trigger: 
arc is ignited and current 
rises  to  the  pre-set 
value.

② 

When  the  spot  welding 
time is up, current drops 
gradually, and arc stops.

Note:  Spot  welding  time  is 
1/10 of the upslope time.
