SHE'S ALIVE!
Thank you to everyone involved for all your help and advice, I would not have done this without you.
I mounted the stud diodes through the aluminium plate, then bolted everything together using thick strips of brass coated steel, put the machine back together and it works a...
I will wait for the diodes to arrive to see exactly what I'm dealing with, then hope to bolt/screw all connections together.
can't wait to see the outcome... will report back when I get to the build stage.
Thanks to all for your input & help so far
Ive had a look & yes, there is an earth sign on the stud of the capacitor at the small plate end so I'm presuming the positive is the other end connected to the larger diode plate end.
Regarding the silicone paste, I have some computer heatsink thermal paste, would that be suitable?
Thank you...
Thank you so much, for helping me with this.
I have found some 70 amp stud diodes on eBay, and was thinking of using just 2 instead of the three diodes (so changing the rectifier to using 4 in all rather than the 6 used as it was originally.
These are the diodes I'm thinking of using, is...
I measured the diodes with my meter on the Diode test and wrote the values next to them (pic attached) the tolerances were out of the range you said, but that could be down to me or the cheap meter?
Ive also spent a long time looking for stud diodes on eBay etc, I can find plenty of 50 amp...
Thats a great explanation Eddie. If there are no part numbers, can't it be worked out by the amount of diodes used & the amps of the welder? sorry if thats a stupid question, but I don't understand electrical workings!
Thank you
Ah I see, I removed the bolt that holds the three eyes of what I know now is the diodes together, to get a closer look. The three strips from each diode have a hole in to create a weak spot (like a fuse I guess) this is where they have become detached. Thought I would try and solder them back...
Hi, I have been given a Migatronic Rally 166, I started with a good clean as it had been in a shed for years, when I removed the side panels, I noticed a damage part, I haven't a clue what its called, or if it can be repaired or replaced. The machine may work as it is but I haven't tried it, and...
Hi, Im Steve from Leicester, I have always been in the motor trade, so mainly just welding patches/panels on cars. Ive used mig, gas & stick welders in the past.
I'm after some help & advice about a mig I have been given, but will will post about that in the right forum.
Just wanted to...
