Drove the 30+ miles round trip yesterday to Airgas to pick up a 10 lbs spool of .030 HB-28. Got home and took the roll out of the box, and could immediately tell I was probably going to have problems with it. For one, the roll is wound quite loosely. Secondly compared to any other roll of wire I've purchased, the wire looks like a tangled up mess on the spool. Lastly, the copper coating on the wire looks like its flaking off.
Anyway, I went ahead and installed the roll on one of my machines. What I saw next is something I've never experience before from a roll of wire. When I pulled the trigger on the gun, I could very easily see the wire cork screwing between the roll of wire and the drive rolls. After this I tried running a few beads. Notice I stated tried. The wire was cork screwing like crazy out the end of the contact tip. I suspected it was going to do this though. Considering the fact that the wire was wandering all over the place as it exits the contact tip, my resulting weld beads looked quite similar to what my 10 year old produces.
Now, I 'm either going to have to drive back to Airgas, which costs me close to $10 anymore, to see if I can exchange the roll for another, or just throw the roll of wire into my scrap bin.
I guess from now on, I'll be removing the roll of wire from the box and inspecting it before I leave the store. In 18 years of welding this is the first time I ve ever got a roll of wire like this.
