max spool size for Miller/Hobart 210?

[D60]

Apologize for the newbish question. I searched around online, best I could find was that the Miller 210 can accomodate a 12" spool - which seems like the smarter way to do it (for Miller) since theoretically every plastic spool could be formed differently, despite equal weights of wire.

But what's the max you guys are fitting in a 210? 40-ish pounds?

I usually buy my wire from the Lincoln dealer if it matters, so it's Lincoln wire/spool.

Any thoughts or experience on if the Hobart's cheaper drive motor will struggle pulling a big spool? Largest I've used so far is 12 lbs.

EDIT: ok, found this at Hobartwelders.com: "Handles wire spools up to 12 in (33 lb) - wire feed speed adjusts from 90 to 750 IPM"

still wondering if anyone's seen increased feed problems w more weight?

I can not remember the weight, but at most of the welding shops around here they sell them in two sizes, something around 4" dia. and something around 10" and I have been buy the bigger ones for my 210.

When I bought my miller 210 the sales guy told me it would hold up to a 40# roll. I'm runing a 33#er now with no problems.

Somewhere in the owners manual for the Miller 210 that I have it says max is 33#.

Right now I have a 40 something # roll in it and after setting the spool and wire feed tensions it works fine for the most part. However, once you get that big roll going it wants to keep spinning.

From now on I think I will stick with the smaller spools of wire.

max spool size is 12" and 33lbs.

Although... I wanna say I have a 40-45lb spool on mine when I bought from the weld shop.

As far as the "it wants to keep spinnning" comment, just make sure you have proper tension on the spool. I haven't had any of those problems to date.

44 lb spool with the wire feed cranked almost as tight as it will go (or it slips) and the spool tension set correctly. Slow to start and slow to stop. 25% more than max recommended means a higher moment of rotational inertia. Tried it, it will do it, gets better the more wire I burn off the spool, but I will stick with the 33# and smaller.

Thanks guys. I bought a 33lb spool yesterday. I only did a quick plug weld but it worked fine for that.

On a related note, any experience w Anchor brand wire? This is what I wound up with.
