The guys here at work have been complaining about the Lincoln 5/32" 7028 rods(Jetweld LH-3800). They have been asking if we are buying second rate rods etc.. The rods will start and weld fine when new, then when you stop and try to restart the rod to tack on something else, the welder has to beat the rods to death to get it to start again.
We went back to the supplier and asked them to come and see. They merely asked the welder "how long you been welding?". Not the asnwer we were looking for. We have run the machine hotter and colder than the mfg recommends trying to find a happy medium. All the welders (65) are complaining about these rods, so I've ruled out technique and welder misuse, etc. and tend to blame it on the rods.
Anyone have this happen?

PS. The welders have been complaining for about five years and we haven't helped satisfy them yet with a reasonable answer. I worked out there with them and their complaints are legit. I too was having the same trouble restarting these rods if they have had a chance to cool.
