Thank you very much. I have an 1969 SAE 300 F-226 gas powered that will fire up but, will not strike an arch. With all the information online, I still cannot find an answer as to why my machine will not weld. I don't really understand the mechanics of testing wires on the machine. Some things I don't get is like, do I test with the machine running, off, do I undo the line before testing, do I leave the line and test as is? do I use OHMs??? and the like. In any case, thank you for your video.
you all prolly dont give a damn but does someone know a method to log back into an Instagram account..? I was stupid lost my login password. I would appreciate any tricks you can offer me
@Alberto Houston i really appreciate your reply. I got to the site thru google and Im in the hacking process now. Takes quite some time so I will get back to you later when my account password hopefully is recovered.
Thank you for taking the time to make this video , I was looking for a spec I have 8 diodes and 7 are all over 400 and 1 is 396 ??? , It is a starting point ...
In diode mode it reads the voltage drop across the diode, so you got 0.422 Vdrop or 422mV which is good (0.3~0.7V), and on the failed one the "zero volts" means short circuit (it "became a wire"), the way diodes like to fail.
@@cozy4build245 I just got quoted that changing diodes on my miller big 40 would be 800$ for parts alone. The guy said the are testing fine until machine loads up and therefore the diodes drop out? I’m a millwright at the local paper mill and feel confident about tackling the job myself but concerned if that’s actually the problem. Any advice would be appreciated.
Hey Caleb I would take out the diodes myself. They will have a part number somewhere and look for that part number on google you can probably find those diodes for less than half of that price quoted to you.
Exactly what I needed to test the diodes in the old Miller.
Late comment but that beeping sound and what it is displaying is that diode it shorted not open!
Had one short on myMiller Econotwin HF. I replaced all four. Works great now.

So wat kind of amp are we talking about ?? Watching from Jamaica west Indies !!
THAnk you so much. Just as another before me has stated, this is the exact information I needed.
Much appreciation.
Thank you for your kind comment
Thanks, this is exactly the information I was looking for.
Glad it helped you!

@Alberto Houston It did the trick and I now got access to my account again. I am so happy:D
Thanks so much you really help me out !

You are welcome. Glad to help

Thanks for the info!
Great video, thanks
Thanks, my issue with my Snap On welder too. Is there any info on your diagram sheet to where a guy could find a copy on the internet by chance?
Wrong not an open diode it is a shorted diode.....
Agree diode is shorted
wish u would put the part numbers for the diodes on
What machine did that diode come off of?
Old Lincoln weldandpower 225

@@cozy4build245 much appreciate. Thank you, will do.
That’s called reverse bias and forward bias.
Thanks
No problem
What if below 400 in reading.?
The diode is damage
Probably not. You just have to know what that diode is rated at. The main thing is to check if it it open or not. See video. Thanks for watching
Probably not. Be sure to check that it is not "open"
Please stop making these you take hrs to say nothing
