Duratech TS1564 solder station

Sir Swampfox . . . . .

So . . .it'sa looka lika' dis :
( I particularly like the heeevee- doodie springy-dingy-thingie . . . and I hope . . .a glazed porcelain or ceramic end cap. )



Do those ree-sistor-es-es visually appear to be bad or is resistance measurement proving them as bad ?

R20 is a 10 ohm @ 1/2 W carbon . . . I would upgrade to metal film.
R3 is a 0 decimal 12 @ 2 watt metal film.
If they HAVE BLOWN, check out all of the the resistance possibilities between the 3 pins
of the . . . unplugged iron hand unit . . . . and then between the 3pins and the outer ground shell.

On the main unit . . . check resistance readings between the Gate to MT1 and MT2 and then between
MT1 and MT2 . of the units power control which utilizes a BT139-600E Triac.

It 'soitanly wouldn't hurt, to have a GOOD SHARP closeup photo of the foil side of the PC board
if any further help is being needed .


BT139-600E TRIAC:



Aside . . .
For pre censorial approval purposes . . . . is OK Chris . . .hmmmm OK hmmmm OK Hmmmm ?

Hi,

I have the exact same issue. R3 & R20 are blown ,,, and D4 is acting like a resistor for reverse voltage.

Same here I searched for a long time .. but did not find anything but this post.

What is meant by "0 decimal 12" what is the value in Ohms?

 

WINNER . . .WINNER ! . . . give Sir Harald . . . . that HUGE stuffed Teddy bear, off the top shelf at the Fair !

I just spelled it out, as I just wanted no error in that low value of resistors decimal point placement.

Now . . . after an interim 3 years lapse . . . I can not pinpoint my sourcing of that info, in being able to confirm that pair of resistors value or anything else.
But . . .design wise . . . . seems like that LOW 0.12 ohm value would be placed in series with the power feed to the irons heating element so as to be a current shunt in reading the power pull of the heating element. Also with that low of a value and 2 watt rating I can't see it overheating unless the irons heating element shorted out.
If we have to figure out anything else, best you submit 2 good closeup photos of both sides of the board.
¿¿¿ Seems like ??? the circuitry of the Duratech 1564 used, is being a similar circuitry clone of the Hakko 936 series of product.

By the time you can finally just make ends meet, then they've gone and moved the damn ends !
