Welcome to the forums.
I think you could be happy with both of those power supplies.
I was able to pre-order some SYNC consumables and an adapter for my PowerMax 85 hopefully I’ll get them around mid to the end of next month.
The Kerf with is the incredible part both those machines when using the new SYNC consumables.
I do think the operating cost for the consumables are going to run on par with the Legacy consumables for the duramax torch.
Myself if I was buying a new machine I would buy 85SYNC. Try out the new features. I think that consumable tracking would be super useful for production and pricing in the future.
One thing to consider is soon as the SYNC start shipping they’ll be a lot of PowerMax 65s and 85s hitting the used market for some pretty affordable pricing.
it’s win-win for both those choices. it really boils down to how much money you want to spend for the extra features.
If you search SYNC in the magnifying glass there’s a few different topics about it . here’s a couple links below too.
