Clogged desoldering station

<< < (3/8) > >>

I had this exact same problem with the same desoldering gun too. A small drill bit fixed in a chuck and slowly turning it by hand in order to not damage the tube let me remove the clog. Not a fun job - ever since I am obsessively cleaning the nozzle using that cleaning wire every few sucked off joints just to be sure the solder doesn't accumulate in it.

Also the advice to let the pump run a bit longer to make sure the solder goes all the way through into the collector is good - I have discovered that as well.

Twice I had a serious clog on my 985.  First time I took the tube off, turned the temp to max, ran it a bit and then used the ramrod to clean it.  The second time, it didn't work so I applied heat from my soldering iron to the inside part of the tube and kept the heat there whilst poking with the ramrod until the clog was clear.  I am now careful to run it for a couple of seconds after cleaning the joint.

And there's me thinking bench vice, oxy & 100psi of compressed air.

Worked for my blocked aoyue tip. I'm always worried the drill bit will damage the plating inside the bit/tube and make it easier to clog.

Afrox ( and all welding shops that stock acetylene welding equipment) has a nifty cleaning kit that is a selection of thin wire files, a simple flat file all in a nice neat folding metal case, used to clean out carbon from cutting and welding heads, which build up a similar ultra hard carbon film as well.  Just start with a small size and ream out till clear.

I find it difficult to remember to do this, and my Pace MBT WILL clog reliably if I forget for a few joints. I have never seen a desolder system with a pump run-on timer, and intend to fit one the next time I have an idle hour.

+1 to this. You must have the pump running as you remove the tip, and you should be wiggling the tip back and forth lightly as you react it. This allows cool air to continue to be pulled through the piece and helps prevent the wire, lead from sticking to the residual solder in the hole plating.
