ok as today i accuired(thread) a bit of time to have a look at a few projects
one is what i hope to be my new stick welder as it adds in the possablity of dc tig (when i get a torch for it) a thermal arc 175se
now the problem its been droped and snaped the pcb
ok recived a thermal arc mma tig welder broken non working for very little money
as can be seen ive found a dodgy power switch sorted that ish (needs sorting but a new switch has been insalled but the hole its in its a bit loose but thats not the problem )
but on closer inspection i found a broken/riped pcb (prob because its been droped)(i was told it was working then it was not so its not a supprise)
now there are 4 tracks 2 on one side 2 on the other the pcb is bent and cracked
ive done a temp cheak removed the broken tracks and put in links and powered on and is working fine (me and son run a few rods tonight before posting this)
but now its working (prob not after i have another go at it but the break is where the board is held in the case (why it prob broke as it was prob droped )
but now the question how to repair the board and install new tracks that the board is strong and the tracks safe
my first thought is (as i expexted remove temp links as only put in there to test as dont want to do a big job to be disipointed it dont work but now i know its working its worth having a go)
so remove temp links cut board epoxy the joints and run the links over the new fixed board ans seal them to prevent any shorts /
so questions
how to repaire the board the pcb cut out replace ? or try fix whats there ?
solder new links in place the ones in pic look big enought to add to the tracks (dont want it burning out)
and is any repair on this bit going to last ? as its on a stress point
could i tag @HughF ive seen hes done one before on such stuff and any help info would be great from the fourm any input would help over the years ive done a fair bit of component repairs but never tryed to fix a pcb or work on such a powerfull unit so need advice on if links are ok
thanks for any help
