Canox migmatic 250mp

Any one own one or know much about them. There"s one for sale around here and I can"t find anything on the internet other than it may be a Canadian Miller. Are parts still available for this welder. Anybody know the max output, duty cycle, etc. TIA

The first picture that comes up with your link is a Lincoln Power MIG 255. The Canox machines are rebadged Millers and identical except for paint colour. The same as Acklands welders which were orange. It looks like it says 250 amp and will probably be at least 40% duty cycle and/or 60% at 200 amps. It's definetately worth considering if the price is right and so is the Lincoln. The Lincoln is a little better because it has digital meters. They look like they've been well taken care of too. Would handle pretty much any job you're likely to encounter. What's the asking price? $1000 or less would be a good deal and it could be worth even more. The little 130 is a 110 volt Miller. I'm assuming your asking about the the bigger Canox? Dave

I woulda thought the Canox 250 would come up first. It's pic 1 of 7. If it's a 250 MP would that be the same as Miller 250. Any idea what the MP might stand for or just some extra letters on the model# The asking price is $1650 on the Lincoln with an $800 spool gun and no tank. The Canox 250MP is $1350. A new Lincoln 255XT would be over $3000 without tax. I was pricing new welders and the best price I could get is 2264 on a new Lincoln 255XT. The spool gun is another $800. Thank you for the quick response

Not sure what the MP stands for. The Canox looks a little newer than the Lincoln and is the same as a Miller 250. The prices don't seem too bad and I imagine they'd take a lower offer. Can you try each of them out? You might like the arc better on one of them. A spool gun is nice to have but not much use unless you plan on doing a bunch of aluminum. They can be used with .023 steel wire though and won't have as many feeding problems. I had an older model(99) Lincoln 255 that I really liked but it didn't like feeding .023 wire. With .035 it was excellent. They may have improved on them since. I'd probably lean more to the Lincoln because you do have the capability for aluminum and with the digital meters, it's easier to set your volts and amps just where you like them. Make sure they all work. Around half price or a little better is the norm for used single phase MIG's and the ones in the picture look pretty clean. They hold their value pretty good too. Dave

If it is the same as the Miller 250, I have read where that unit was a mistake by Miller. They discontinued it right away and came out with the MM-251, and now the MM-252. Reason being as the inexperienced weldor had a hard time finding the sweet spot. I have a mechanic friend who has a MM-250 he was complaining that the machine didn't work very well, thought it might be his incoming power. I told him this same story, I said I like to give his machine a test drive, so I could tell for myself. He gave me a funny look and changed the subject.

Puddles, I saw your post from the other day but don't know if you saw my reply. I think you'd embarrass anyone who claimed to know how to weld including myself. I liked a Lincoln 215 over an older MM 200 when I worked at a shop that had both. The Lincoln only had 5 or 6 voltage adjustments too, while the Miller was infinite. I have used Millers that I liked too though. Dave

No I didn't see your reply, thread must have been deleted. :wink:

Personally I wouldn't own a taped wire feeder / Mig machine. I like having complete control over the puddle. I don't use the inductance on my machine all that much, but I know its there when needed. I can wet the puddle, or dry it out to suit my needs. When trying to do that with just infinite voltage dial you can easily get yourself into trouble by having just a little too much voltage, and your welds will be brittle. Or the opposite could result in cold lap.

I agree that infinite control is way better but the Lincoln I used still had a nice arc. The Miller was also on the high range voltage setting which I think made a difference. The cable plug in seemed seized otherwise I would have tried it on the low voltage setting. I didn't want to wreck it trying to loosen it and didn't have to use it very often. Brittle welds, cold lap, cold starts, lack of fusion, porosity, etc., etc., and some people wonder why I recommend a stick machine for an inexperienced welder. I'm not saying MIG can't produce excellent quality welds but it is more prone to flaws until you get it figured out. Some people think a brittle weld is stronger though but not me. Dave

i dont think the lady selling it would have a problem with me trying it out . she said she and her husband used to run a car restoration business and her husband had died said the lincoln has seen very little use she said the lincoln is about 5 years old and the canox is 7-8 years old. i think the ages would be correct because she knows what they paid for all of it. i might have to supply a tank to test it but that shouldnt be a problem

That would make sense. The Lincoln looks more covered in dust and is a newer model. The 99 I had was a Wirematic 255. Canox (Canadian oxygen) was bought out by BOC gasses several years ago and Miller no longer makes machines for them. Serial numbers on a Miller are easy to decipher. First letter J means 80's, K is 90's. KA***** for example would mean 1990, KB would be 1991. I'd guess the 2000's would start with an L. If you type in the model on the Lincoln site for a manual, the last year for the manual usually comes up(same for Miller). If you have the serial numbers you can get even closer. Dave

I couldn't agree more Dave!
Only plate test I ever failed was vertical up with Mig. One inch thick plate, 1/16-inch wire CO2 gas. 3/8-inch side bends.
Funny story: I had been welding oh about 5-years, (all stick, only ran Mig in school) went to get a job in a fab shop. Testing with about six other guys. I could tell the hard nose inspector was itching to look guys out as soon as possible. He would walk from one guy to the other looking over their shoulder watching them weld. I was correct he started telling guys they weren't going to make it. After the first 2 or 3 guys left, the next few he would bring over to me, he would say, when your welds look like these come back and I'll see about testing you again. He looked everybody out but me, I was allowed to finish all three plates, horizontal, vertical, and overhead. He told me to go ahead and prep the test plates for the bender. He ran the bender with me standing right there, the vertical coupons failed. He gave me that look of a cross of betrayal and embarrassment! I could have crawled in a hole. They were beautiful welds, but I ran them too cold! Never happed again! Out of his own embarrassment he let me run the vertical again.

I'm leaning more towards the Lincoln seeing as it has infinite voltage and a spool gun. I likely won't use the spool gun very often but it's nice to have that option. I will try them both out and see what their like.

I had to do a roll welded 2" pipe for a job test with a MIG root. It was with an XMT 304 inverter. I'd never used an inverter before but put in a really nice looking root with 7018 fill and cap. The foreman even said it looked really good. I was shocked when he came and said one of the coupons failed the bend test. He gave me some more pipe and I redid the test. I didn't really do anything different the second time and the coupons bent no problem. After working there a while, it did seem like the inverter machines were more prone to flaws than a conventional machine. Piping(elongated porosity) seemed to be the most common problem on X-Rays. Nobody seemed to have an answer why. Dave

The digital meters are a real plus! I love the ones on my Dynasty 300. Good friend of mine grandson is in welding school now, he was saying the new miller machines they have at school the digital meters hold the display settings for so many seconds after you stop welding so you can read them yourself without a helper to tell what is going on. That is really nice! 8)

You can preset your volts and amps/wire speed with a lot of digital machines. It's real nice when you know exactly what you want or use different wires and/or settings. Dave
