It might be worth taking it to the welding supply and having one of them take a look at it.
Could be the welder itself:
-Liner needs to be changed out because wire is sticking inside (that happened to me).
-Feed spool is too tight and binding/jerking.
-Diodes transformer or whatever are not working properly.
You should double-check the wire feed before at different angles before laying any bead. A few inches of wire lost is nothing. Try to maintain a straight line right to the work. Always keep the gun tip clean as snot.
This eliminates one possible big problem.
(But in my case it is usually operator error.)
