    Miller Challenger 172

    I picked up a Miller Challenger 172 MIG machine. I am new to the MIG process altogether but find that I like it.

    I think this machine is fairly old but it looks as good as new, except the previous owner kept the gun lead wrapped too tightly and abused the gun. I was under the impression that it was a M-10 gun, however everything on this gun is different except for the tips. After visiting several LWS, I left realizing that I had the M-10A gun, put out by miller before the M-10 came along.

    After seeing that I liked the machine, I bought a small fortune in consumables and two liners off of Ebay for an M-10 gun. I have not pulled the liner out of mine to see if the one I purchased would work, but at the LWS in their parts books, they were different p/n, so i am guessing the M-10 liners will not work. Now my question is, if I purchased a new M-10 gun, will it be plug-and-play with my machine? Also, what are the differences between the M-10 and the new M-100 guns?

    Hey gc,
    I have a Challenger 172......absolutely superb MIG unit & has never failed me thru some brutal production runs. I love mine.......best $175 I ever spent(used). Mine has the 10A gun which I believe was the standard gun assem. furnished. I also have a spare GA17C that I believe will also work...haven't tried it yet. I would suggest to get the 10A replacement if you want to replace it. Probably find one on E-Bay quite reasonable as I got the 17C there for $50 & it was new.

    Well i did not get mine that cheaply, but not for off nonetheless. I have searched the internet and Miller's website and cannot find any parts for this 10A. Apart from looking through some old dealer parts books (2006 and older) at the LWS, I would not have even known I had an M-10A gun. They can order one for me, at the cost of a new M-10 gun, but that would render my M-10 parts useless, and leave me with an old gun that I have to special order from a miller dealer, parts for.

    The Challenger 172 came with a Piecemaker 10-A prior to serial KK118238 after that they came with an M-10.The M-10 has been replaced by the M-100.An M-100 would be a good replacement but it does use different nozzles than the M-10.
    If I was in your shoes I would look at a Bernard Q1510AO8BM.This a 150 amp 10' std handle fixed short neck Centerfire gun with a Miller back end......nice gun!

    Thanks for more information than any Miller dealer or LWS has had to offer.

    I am a newb to MIG, so I pretty much only know point, mash trigger, and lay beads. It looks good but when I move the lead while progressing my weld or if any spatter hits my tip I am done for, the wire kinks coming off the feed roller and there I am fixing it. It gets old. I can "feel" the wire being fed through the liner and it seems like I am getting a lot of feedback, so logically I am thinking liner, but I just can't find parts for this gun. I thought I was right in it being an M-10 and didn't have my machine handy, so I ordered everything I needed for the M-10, and got two of everything and 20 tips. So I guess I need to pony up and get an M-10.

    As for the Bernard, I have heard they are good guns, but putting Bernard Q1510AO8BM in google yields little results, and weldfabulous is the only company that has them on the market for what I have searched anyway. Almost looks as though if I buy that gun, I will have a time finding parts for it in the long run.

    Any more thoughts or suggestions would be appreciated.

    The M-10 has been superceded by the M-100 so unless your lucky to find a new old stock one you'll have to settle for a used one.

    I found this on Bernards website,
    http://www.bernardwelds.com/products...ator/step6.php

    This comes up with a different part number than the catalog I looked in and it's a new catalog.....I think

    The M10 and the M100 use the same consumable parts.
    either gun will replace the 10A gun.

    Now I see why they call for different part numbers on the nozzles......one is copper and one is brass

    I know on the Miller 130/130XP (Little brother of the 172) they had a smaller Miller bayonet gun back-end then the standard Miller units. The Little OXO guns sure were nice on the XP model.

    Looks like the OXO handle is still available from Benard..

    I went with the Bernards, actually Prostar gun, and I really like it. A definite upgrade well worth it. Good feel, thanks for the info all.
