Spot welding (TIG Punkt) 

 
Spot  welding  in the device gives  you an option to make short welds in  a given time gaps. Using this 
feature there are fewer parameters to be set: pre gas, welding current ( 

Is

 ), pulse balance, post gas 

and a time gap between the welds. To conduct welding you need to press the torch button and hold it. 
Device  will  provide  short  amperage  impulses  in  a  given  time  gaps  e.g.  if  you  set  the  time  gap  for  5 
seconds and start welding you need to hold the button constantly and the device will provide amperage 
impulses every five seconds.
