Status
Iron has a new tip and hot air is now working. Please do not switch the unit off immediately if you've been using the hot air. Instead switch the heater off and then wait for the pump to stop.
Specification
- Make: KADA
- Model: 852D
Supplies
Tips
- It appears that Kada don't sell tips, you are supposed to use Hakko tips such as these from eBay
Heating elements
Installation is a little fiddly.
- Undo screws holding handle together
- Cut away heatshrink sleeving over 2 wires leading to heater
- Unplug bared crimp terminals
- Earth terminal should just unplug if necessary
- Power terminals are soldered as well as pushed together. Heat while unplugging.
- Unplug white plug block (thermistor connection)
- Remove element
- Replace element (teabot, can you add some notes since you found out how do do this right ?)
- Thread new heatshrink sleeving over power wires
- Note that wires are easily confused as both one of the power wires and the earth wire are black. Do not mix these up. Check continuity to earth pin on mains plug if unsure.
- Connect thermistor plug
- Connect power pins. Solder pins together. (I don't know why this is needed but that's how it was ..)
- Replace heatshrink over pins. Note that there is mains voltage on these pins so be careful that the sleeving is undamaged and will not be pinched.
- Reassembly is the reverse of disassembly.
- Hide leftover parts
Log book
9th May 2011 - Elliot
- The earth lead had become detached from the nozzle. This had been spot welded and could not be soldered (the solder would melt). The nozzle was drilled and riveted instead.
- The element was moved further into the nozzle and secured with the internal plastic spacer (this holds the wire and is not near the element). Consequently the element doesn't arc now.
28th April 2011 - Adrian
- Fitted with a new element but this was shorting and blowing a fuse.
- The seller of the replacement element also sells a complete hot-air handle unit which may be required. However, I don't think it's a straight plug-in on the model we have.
