something happened to my preheater t8280

Postby drwcifer » Thu Mar 12, 2015 8:17 pm

I was reflowing a ps3 and soon after I hit 225c and was able to nudge the chip, my preheater mad a hissing and a pop noise and a bit of smoke came out of the left side. Ill assume a plate burned out. Im waiting for it to cool off then ill put a tc on each plate and see if ones not working. I ask if this has happened to anyone in the past. If its toast, I am thinking about upgrading if someone can give me some advise on a good table that wont cost an arm and a leg, my ears are on..
Thanks

Make sure machine isn't plugged in and remove cover to check a visual to see if you can tell what fried before trying to operate it again. Could have been
the SSR (which is a simple cheap fix) or it could have been control board, wiring, or IR plate. There are places to buy plates, but that's about the only
part I have seen anyone sell for this machine. If controller board is crap now, you can mod it with a cheap PID controller with type K TC like a REX C100
or other.

Whew, thanks for your reply. After it cooled and I removed the board and jig I found a nice fried puddle of flux. Rechecked everything and its ok. Haven't been on in awhile, been out of town last few months but am glad to be home and following this site

Wrong but found the problem. It was my power cord. Guess it somehow worked itself loose and it shorted out

That is a pretty common issue with the t8280.
Skylinenismo knows all about that. lol
He sees this alot with his setup because he uses it so much.

Took it apart and one of the internal wires to the male plug broke off and hit metal and that was that. Good thing I have a soldering station lol, so was able to fix it

I am guessing that you have a 110v version 8280. And probably Skylinenismo too. 220v version would probably not have a issue with this because
you run fewer amps with higher voltage to attain the same wattage (power). I have a 110v version, but not heavy use like you guys do. Just hobby
for me, which I done with. For the guys in US buying the 110v, I would mod the machine as far as how the power is supplied and use larger gauge
wire for power cord as well if your machine gets heavy use.

If your machine is 110v version, it sounds like the wire coming from the plates back to neutral was the one that came loose. Is that right? It would
just arc on the the case of the machine trying to complete the circuit for the plates.

Funnily enough Justin and I had a conversation a while back regarding the plug and he has had to change his twice that I know of , I will ask him what he changed it to as I hunted down a version that is basically a upgrade with a studier casing and better fuse housing
