Clarke 185e, no wire feed

[Hutcho]

The board I did today was slightly different as it had two more push on tabs above the in/out - this board was doing the same thing as yours till the penny dropped - but my two tabs was for a fuse (bypassed for test purposes) - but when the torch wires was pressed it would pull contactor in and out till released - but yours don’t have those - is the stitch timer off ?
Apart from checking for dry joints to start with I don’t know .

I have same board as in 205te thread.
Monomig 186 welder.
The only led on board on same end as timer and speed pots.
No wire feed.
Found fuse blown.
To pull wire through liner was all but impossible.
Found all 3 triacs blown.
One was shattered.
I think it was the one for braking motor.
Replaced triacs.
New liner and fuse.
Worked after that.
If you have 24 to 28v ac available, aliexpress can help.
Search nbc tap type carbon dioxide control board.
Cheap .
Have installed a half dozen of these to various machines.
All out there somewhere still functioning.
Board comes with a 22k ohm pot.
Using this pot gives speed control in a very narrow band.
Fit a 10k ohm pot to get better span of control.
Of note, stumbled across a 2t/4t conversion board on aliexpress.
Search tig welding plasma gas shielded welding 2t/4t conversion board circuit board.
Looking at getting one of those to have a play with.
