  • Arduino PID Controlled Lee 4-20 Metal Melting Pot

    The idea of adding the PID it to get to temp easily. Just set and cast. The way that the pot was working previously was utilizing a thermostat to regulate temperature based on the exposed element within the case. With the PID it is regulating the temperature based on the lead itself. I notice a big difference when the lead level falls. No more need to rest and re-calibrate during sessions. Re-adding sprues and flawed bullets also is not a problem any longer. The recover time is next to nothing. The SSR terminals are isolated using hot glue to fill the contact area. i thought to use liquid tape but the hot glue is alot easier to put off if ever the relay needs replacement. I do have a shield for the lead splash i just left it off to avoid camera flash. I will address that in the video th...

I do have a shield for the lead splash i just left it off to avoid camera flash. I will address that in the video that i'm making for it. I just posted this instructional last night so haven't got all of the pieces put together yet but thanks for the heads up and i will add those two things you mentioned to the instruction. Thanks for the comment.
