Great, could you please tell me the reference?We use Photobond resin of some kind, I can tell you on monday when I get back to work. We specifically had them recommend us some type that would not harden completely but into a silicon like substance so it would be easy to remove from the thermocouple and not destroy it. Yes you can solder or weld a new tip depending on the type, but it is unnecessary hassle.
We use some modified Ikea lamp with UV-A bulb mounted instead of the original one, and foot pedal to switch the thing on.
I usually just hold the joint with my hand and turn the uv on, abou five to ten seconds to make it hold and about ten more to be fully cured.
