Complete and utter newbie here. Just picked up my first welder today (bought used) and have started to fiddle with it a bit. The first thing I noticed is that coming out of the mig gun is a bent coil of wire (see picture). I have no idea what it is as have never seen it in any pictures or videos. When I pressed the trigger to see what would happen (haven't got gas, tips or shrouds yet) the wire feed drive wheel is just slipping and no wire is coming out of the gun. I presume the two are linked and am not even sure if it's a problem, or just something I don't know about yet.
Thanks for your help.
