Welding Wire issues?????

While it will not affect your weld it will eventually clog up the liner in the gun causing feed problems. It is usually best to store it in a plastic bag too keep the moisture out of it. You can pck up some lube clips which will wipe off most of the surface rust before it gets in the liner. http://store.weldingdepot.com/cgi/weldingdepot/LUBExa.html?id=xUU6jnJF
