We currently own an elderly electrovert wave soldering machine. Does anyone know or have access to the up / maintenance manuals for the machine? If so, do they know where I could get hold of a copy? Best Wishes, Richard Jones

Try tinning a few parts by hand and place them into the paste and reflow. If they solder fine then, you have a plating problem. Common sense goes a long way.....

Hey, I've been working with various Universal Gold Feeders sizes, and I've seeing that the sensors are fairly fragile. Any other users of these feeders seeing this? Of course the manufacturer says we are the only ones seeing these issues.
