I paid enough that it should sew with 40 wt and should sew with spools, not just cones. Amy Gibson, famous for her sewing, uses 50 wt. Presencia thread, like I use now. Don't let anyone tell you it's not strong enough. It is! If they buy spools of Mettler, they are buying 50 wt.
Any serger thread I've seen for sale is much thinner than 50 wt. Presencia sells 50wt. cotton thread on spools. If you are having issues with your Bernina 830 I would suspect it's because you're using serger thread. The new 830E's are very fussy about using quality thread. If you're feeding serger thread through it, I question why your dealer would tell you that.
People may be misunderstanding that a cone of thread is serger thread. It is not. There are many, quality brands of thread on cones that are not serger threads. This is a thin, serger thread, 100% polyester

Superior threads has a free (for now) CD that will teach you the different applications for the different types of thread on the market.
Superior threads say, "Serger Thread
Because sergers (overlock machines) simultaneously use multiple cones of thread, there are many cheap serger threads on the market. The cones of serger thread available at discount chain stores are an inexpensive spun poly. These are OK when used for serging but not recommended for other applications. Multi-filament polyester thread such as So Fine! #50 makes a clean, lint-free serger thread but is more expensive than spun poly. Omni Thread is a poly-wrapped poly core thread ideal for serging."
