Miller Aerowave owners, need help with identifying a resistor

admin

Anyone willing to open up the top of their machine?  I have a burnt out resistor and it is not identifiable anymore.  The board should be accessible from the top or maybe a side, it is shown on the diagram.  I am looking for the colors on resistor R1.   If I can figure out the resistor I can at least try and replace it, but with no value, I don’t dare guess.  I have the technical manual from Miller and it doesn’t offer any detail of the circuit boards for this machine.
Reply:I know these are a tough machine to even want to fix, but someone must own one and be willing to help a guy out.

Reply:None of the manuals break down the individual resistor values for this board, the part you are looking at is for something completely different, if you look at the diagram it isn't even in the same location.  Here is what the part you are seeing looks like:https://www.amazon.com/Miller-141424.../dp/B004HE6A18

Reply:Spoke by PM, depends on access time to get to it.   May have to wait a bit.
Reply:Glad you got a hold of him.  He's the only one i know of on this board that still has one.  They are pretty rare these days.Miller Syncrowave 300(s)Miller 330 A/BPMiller CP-200 Haas / Kamp'd / CP-300 in processMiller Radiator 1Miller 30A /S-52E feedersHobart GR-303
Reply:It's negative 7f this morning here, another place to try is instagram and search # welder repair or aerowave  I know someone goes by @arc doctor or@mxrider168 and few others on there, otherwise I'll get out there as soon as I  can get some help weather /health is not the greatest lately, craigslist chicago had one for sale recently but I don't know the specifics or if still there
Reply:Just a FYI there is one on the Tampa CraigslistRichardWest coast of Florida

Reply:No rush at all, just hopeful I can figure this out.  I think I may start to write up all the other components for future reference.  I really thought the Technical Manual from Miller would have the list of them, but nothing more than a PN for the board, that has turned up almost no info so far on the web.  Found some place saying they offer it, but no response yet, I figure it is a huge company and they don't want to deal with a little guy.

Reply:I think it would be nice to have a record of the boards, biggest issue will be my knowledge, but I guess good photos can probably make up for that.  I think there are 8 or nine boards, one of them is scary loaded with stuff, probably take hours to figure everything out.
Reply:After a discussion with one of the long time Miller reps, I got more info.  Miller has all the individual values for the circuits, I just had to tell them the circuit number.  So now I know what I have to buy for replacement resistors.  Here is a link to the Technical Manual for all you Aerowave owners, it may be helpful at a later date.  Not sure how long or how well the link will work, PM me if you need more info.https://www.dropbox.com/s/vjb0l4bm2x...anual.pdf?dl=0

Reply:Well the pic will not upload if you still need it let me know.
Reply:Can get pic to upload if you still need it let me know.
Reply:Lets try this again, come on pic load.
Reply:pcb is the AC clamp board. only used when welding in AC. If memory is right, coiled weld leads can cause problems with the clamp pcb. Miller doesn't have many parts left for these machines. Its job is to reduce the high voltage surges in the AC weld voltage to a safe level. in DC it is not needed.
