I am a newby on here and am having some problems with my Hobart Handler 140. I bought it a few years ago and have had no problems with it whatsoever. I went to use it the other day and the drive wheel is slipping and spinning on the flux core .030 wire I am using. I have put alot of this wire through this machine and never had a problem with it until now. When I go to weld it will spark and burn the wire up the the tip. I change the tip and adjust the speed and voltage and the drive wheel is spinning on the wire.
I bought a new drive wheel with the grooves cut in it to help push the wire out and that didnt do it. It still just slips on the wire. I put on new tips and have changed the diffuser. The roller bearing surface isnt worn out.
Im running a spool that is not the smallest (2lb?) but the next size up--5lb? I wonder if the spool could be too hard for the drive motor to pull? Or maybe rubbing the inside of the case?
The wire moves freely back and forth by hand inside the liner of the gun etc so I dont know what else it could be....
Sometimes I can get it to weld good and then it slips and the welding is over...
Any help would be great!!!
Thanks everyone!
