Good evening to you all. This is my first post on this fantastic forum, although I've been getting some fantastic information from it already looking through other posts etc. So I've managed to pick up 2nd hand GYS Smartmig 162 at a sensible price. It came with gas less wire, but today I've purchased a gas bottle, regulator, wire etc. I've now gone to put the big spool of wire in, it will fit, but the hole in the middle of the spool is bigger than the little spool that came with the machine. Am I missing something on how to fit it or am I missing something from the machine. Any ideas would be gratefully appreciated. I've attached a couple of photos. Many thanks, Paul
