Evening all,
This is a repeat of my post on baz-r's thread but I don't want to hijack that with my new problem.
"Problem is whilst the electronic feed mods worked a treat on the worktop, when i went to use it in anger today the motor just goes flat out when switched on, neither the main adjustment or the trimmer has any effect.
When tweaking the welder last night I could set the feed to a crawl with the main pot at min and the trimmer at about halfway (my trimmer was a 100 Ohm as standard - circa 1997), today the motor sees 24.5V when on min voltage, 33.5V on max voltage, and proportional to those readings on the other settings."
So far searching the forum it seems there is a transistor which if faulty would create these symptoms, how do I test it?
At least the mechanical mods worked a treat!
Thanks in advance, nick
