Pro core 100 slow feed

admin

Hi all,Sorry if this question has been posted, I couldn't find an answer.  Been welding with the pro core 100 for 4 years.  Never a problem with it till today.  The feed roller is going it's correct speed.  But once in the hose a foot or two, it slows down considerably.  Is the hose dirty?  Something wrong with the gun?  Ive looked ay everything else.  I appreciate your time.JasonJason

Reply:Thanks for the replies.  Turns out it was a bad spool of wire that was , i guess, wound wrong on the spool at the factory.Jason
Reply:Rare problem. I have seen the wire get crossed and knotted and stop the wire from feeding.
