SP100 and 10# spools

admin

I have an sp100 that gets almost constant use as of late and I've been going through a few 2# spools per week, so I thought I'd give the 10# spools a second try. Last time I used a 10# spool I started with Forney wire, got about 10% through the spool and it started binding, so I shelved that wire and got a spool of Lincold wire, same binding started happening. I did some investigating and found out that it was the adapter causing it to jam, it just wasn't running smooth enough. Any tips on making that adapter spin more freely?
Reply:I put a piece of wood insid the threads for the adjusting nut.  It tightens as the wire pulls on the roll ( for the 2 lb spools).  Othewise never had a problem.  I only run 10 pounders unless its stainless.DavidReal world weldin.  When I grow up I want to be a tig weldor.
Reply:I was going tosay i've never had a binding proplem with a 10 pound spool, but I did have a proplem with the smaller ones, thanks to davidhere i just fixed that proplem, Thanks David it sounds like that will fix it, i was getting tired of rolloing out wire and welding a few inches before winding out more wire.
Reply:I had the same problem with mine, but i just loosened the spool as much as possible and tightened the feeder roller a little more.  The problem is that the feeder isn't getting enough traction on the wire to overcome the resistance on the spool.  This becomes much more pronounced with the added weight of the 10lb spool.  I have it where the nut on the spool is just there to keep the spool from falling off, but not putting much pressure on the spool at all.  For now the spool seems to have enough weight so as not to allow it to unravel in the welder like a 2lb spool would, but as it gets lighter i'm assumunig i will have to increase the pressure on the nut.  I just check it periodically.
