Are you using nitrogen with your wave? You probably will need to with selective. With our Ersa we need 99.9% pure nitrogen to make it acceptable. They spec 99.999% which means liquid nitrogen. We tried one board without nitrogen, it left a two in

We have an ERSA Versaflow Ecoselect selective wave soldering machine. It works well except it needs nitrogen. You can't even move the table around if your nitrogen tank is empty. The spec sheet says Required degree of purity: Nitrogen liquid 5.0

We have an Ersa Powerflow N2. It's a very well built machine with excellent support. We run it (2) 10 hr shifts per day, 4 days a week. Having the full nitrogen tunnel has greatly reduced dross and improved hole fill. This replaced an Electrovert Vec

We aquired an ERSA ECOSELECT 2 selective soldering machine. So we are going through a learning curve and I would like to hear from ERSA users on this subject. The main concern is to keep the miniwave steady, it seems that it " bounces" a lot and is

Seho maxi wave 3240 should be considered as well. Invented full tunnel nitrogen systems that have lower operating costs and provide yields unlike what can be achieved by air wave systems.

Hi, I am ok either way, and the main reason I originally went with Soltec was the overall oven design seemed cleaner than ERSA. The soltec had good performance, but the oven design was neat internally, where the ERSA seemed to be a bit of a mess.
