Phil and Jim, very good. Used correctly, nitrogen can strongly reduce dross production in wave soldering machines. With our system, we are able to reduce dross formation by more than 80% when compared with air (or other N2 injection devices). We dropped flux consumption near 50% as well.

I have a Hollis TDL12 that is working properly but the last few years the dross production has been overwhelming. I will implement an on/ff switch for the wave, although I have seen that the wave stabilizes after a few minutes after initial heat up and I learned that its important for the wave to work for a while before soldering boards. Thanks.

Hello Phil and Jim. I'm suprised that you guys didn't mention the EVS Solder Recovery System. With proper de-drossing, the wave will do it's job and with this system, it's possible to reclaim up to 70% of usable solder from each de-dross. Unlike N2, the machine will pay for itself and will not add cost to your soldering process.
In fact, I've heard claims of companies reducing solder purchase quantities by up to 40%. At an ROI, in many cases, of 12 months and under, this is a product you all should be aware of as a wonderful solution. Thanks guys.... I enjoy your bits.
