CAUTION

 

● 

Never attempt to disassemble the feed motor. This may result in damage to the wire feeder. 

● 

Never check the amount of brushing friction or replace the brush. 

 
Service  life  of  the  brush  varies  depending  on  ambient  temperature  and  welding  condition,  etc.,  but 
normally  the  service  life  is  about  4,000  hours.  (If  the  machine  is  operated  for  six  hours  a  day,  the 
service  life  of  the  brush  will  be  about  two  years).  Periodical  replacement  of  the  feed  motor  is 
recommended.
