WEP 858D - cheap popular hot air station.
Bought 3 years ago for ~$30. Lightly used, mostly for desoldering and heatshrink tubes, perhaps total 10 hour of work. Heater silently (without sparks or anything like that) failed last week.
Wiring:
- heater
- thermocouple (inside heater element)
- fan
- miniature reed switch, working together with magnet in holder on base unit
- ground
Heater is insulated with glass-like (box on new one says this is actually mica) canvas.
Failed heating wire. As it was broken near the end I actually could try to save it by removing shorter part completely, though it might be difficult to connect this type of wire - low temperature soldering would definitely not be an option.Thermocouple at the working end of the heater.
New heater costs ~$4 + shipping.
Fun stuff: "Gift" label on the box itself.
Don't forget to remove piece of transparent tape that is holding insulation together.
Watch out for thermocouple polarity.
Heater resistance: 98 Ohm, matching original.
