We resolved this issue a few weeks ago. It was a configuration mismatch in the oven (MR933+)software with the onboard O2 analyzer.

Low-consumption Nitrogen configurations with an on-board O2 analyzer is the ideal way to go. I cannot speak for all oven manufacturers, but ours have N2 fed to the reflow zone only, which to me is really only where you need it. The gauges/flowmeters

| We have a Vitronics SMR400N oven and many times need to use N2 inerting. My problem is that it takes close to an hour of operation to purge the system to achieve the desired O2 levels (~40PPM). This is not only time consuming but results in an inor

Folks, we've recently upgraded to Heller MKIII reflow ovens with Gen 9 cooling units. We're running N2 atmosphere at 1000ppm O2 and Kester256 solder paste. We're seeing a big problem with flux residues building up in the cooling section of the

You might consider an oxygen monitor (or lack of oxygen monitor). A fast response-rate analyzer should be used. There are several types of analyzers on the market and each has different limitations. * If you are looking for a measurement ranging fr

Sorry to hear of the difficulty with the rails on these systems. The 2 machines mentioned are 10 years old or more. The rails typcially last quite a while but replacement after 10 years is possible. Please feel free to e-mail me directly to discus
