ZD915 80 Watt De-Solder Station Jaycar TS1513 Modifications.
ZD915 80 Watt De-Solder Station Jaycar TS1513 Modifications.
I recently got fed up with the high noise level (about 199 dBA) out of my newish ZD915 generic type de-solder station.
Neighbours were complaining.
There must be heaps of these things around the world in one ZD type or another.
They work well enough.
I moved the internal air pump and PSU unit to the front by 15mm, by drilling new base mount holes, so as to get space for mounting a new fan.
I installed an 80mm 12 volt 80mA silent fan (and finger guard) Jaycar YX2570, by re-using the original top left mount hole, and by cutting a new hole in the rear panel.
Used some small rubber edge trim for aesthetics.
The station air extraction now works; the original vent holes were far too small, and contributed to the noise.
As the original fan was a 24 volt 40mm unit running on approx 18 V DC, I installed a 7812 +12V TO220 plastic case regulator on the top side of the PCB (which only has two R1 5W resistors), in the fan feed only, in the little plastic box at the rear.
This means that the 7812 has two ohms off 18 volts, and maybe generates about 0.5 watts heat.
I lashed the modified box to the front of the PSU with cable ties.
While I was working on this unit, I raised the angle of the solder gun holder to 55 degrees by cutting the original fabrication welds and using two small pop rivets.
I threw away the sponge and tied a kitchen stainless steel scrubbing pad (with no soap) to the sponge tray with 0.6 mm iron wire to use dry as a tip cleaner.
Much better than a wet sponge.
Removing the (Jaycar TS1386) gun clear tube for cleaning was a bit difficult, so I removed a cable tie from the air tube at the top of the gun, inside, so as to allow a little more rear movement of the back plastic pull back thing.
This internal tie is not really needed, as there is another at the gun bottom.
I coated the tube internally with a wipe of spray silicone to facilitate later cleaning.
For your info, when new, I measured the vacuum at the station front inlet at 25 inches of Hg, or about -12 PSI, and 22 inches at the gun tip.
I used an auto vacuum gauge.
Amazing transformation, very quiet, easier to use.
You won’t need mod photos, as small difference may occur in other ZD types; check suitability before you modify your unit.
If you are able to do this, you will figure out how to your own mods on your specific model.
