My solution, apart from bring it into the house when I've stopped welding, was to get my wife to hold the end of the wire and walk it down the drive while I held some emery around the wire. Then I reeled it back up.
I found that about 20 yards is enough
Must try that one, although as my drive is not that long I just hope the traffic will stop for her!
And being called by your sunday name you must be in trouble!
