Hi Folks,
My 1st post to your forum and thought I would share my sticking wire experience with my old Cebora 140. It's been a reoccurring problem for years using different brands of wire and so once again I did all the usual things of blowing out the feeder tube, cleaning out the tip, checking the adjustment on the feed roller and spool tension, etc,. And yet the sticking wire still remained a problem on some occasions. So with the side cover off I decided to run a couple of meters of wire through the torch and noticed that sometimes when the wire was on the inside of the plastic spool it started to stutter and stick.
My observation of this behaviour was that the wire on the inside of the spool was binding and the little motor (looks like an electric model car motor) in the feed roller could not overcome the additional strain caused by the binding. So in desperation I sprayed the wire on the inside of the spool (both sides) with a teflon spray to see what would happen.
To my surprise the spray fixed the problem and I can now lay down long beads without any sticking and stutters.
The spool of wire is mounted vertically so any excess spray should drip off but to be on the safe side I added a felt pad over the wire just before the entry in to the feed roller to remove any excess spray. And so far there has been no roller slippage caused by the spray. I also have noticed that splatter has been reduced.
And I'm sure there is a more appropriate spray to use. Or better still a better quality MIG.
Cheers,
