Glad you are happy with my recommendation. I've had many trouble free years with my machines. But do yourself a favor, throw that dual shield crap in the dumpster and get some solid wire and C10. Your lungs will thank you.
When you were explaining how the smart board works I immediately began wondering “Wouldn’t the reason why the gas isn’t flowing be because you were testing it with pulling the trigger while feeding wire and thus w/o striking an arc?” BUT since the relay was bad on the board you were never gonna be able to strike that arc so NICE PERSEVERANCE! I’m impressed Miller Support was willing to talk you through diagnostic over the phone for one of their products that’s 30+ years old. I think a lot of people forget they CAN CALL a manufacturer and not just search google but also forget that for a company to maintain Service & Support you need people who actually understand the inner workings of the product AND CAN COMMUNICATE it to you. Could the reason for the welder being auctioned off come down to something as simple as a failed 20cent relay?😅 Rhetorical Q: “What good does outsourcing customer support to India if the person who answers your call has never worked on the product let alone touched or even seen what you’re asking about?
Van that bar at 27:05 is the cable strain relief, all your leads should pass up thru it then connect to the lugs. Your are smart enough not to tug on the cables but its a good ideal to use it. All in all you made a great buy on that top of the line Miller, I enjoyed the video on getting it up and running!✔
I bought a Linde Mig Welder about 15 years ago or more....same setup 3 PH Mig welder unit on top etc... 100% Duty Cycle...for $300 ( 🇨🇦 ) from a Farmer ( who bought it off an auction and didn't have 3 PH ) ...i had 3 Phase in the city shop i rented...worked Awesome ( had Pro Welders test ut and they liked it.... I added a Spool Gun for Aluminum welding ( Pro-Fax adaptor and Old style Spool Gun...) that worked great too... i moved about 15 years ago outside city to my acreage and had to sell it ( no 3 PH here )...i looked at getting 3 PH out of 1 PH but decided it was not worth the expense... sold just the Welder / Mig setup for $400... kept the Long Power Cird i made and Spool Gun and even the Fugly homemade Welder Cart ( i can adapt it for something later ).... so no real loss $$... sure enjoyed the short time i used it ( 1.5 yrs approx..) I still wonder if i kept the Mig Part i might have had a use one day? The Spool gun will be used soon again...i got a Miller Gas Welder i can setup or maybe find a 1 PH Mig Welder for it ( i have a smaller mig i never tried it on ( Lincoln 175SP )... it worked perfectly from the day i wired it up...and was a Solid unit...
CP 300s are solid machines. As much as I like inverter welders I am still old school and like the transformer machines. They just run smoother in my opinion. Good fix on the feeder. Just FYI the 1/4” round bar bracket just below the terminals on the machine is essentially a cable management system slash strain relief. Nice work on the repairs. As far as the dual shield, I am a huge fan of it especially if you are going to do any structural steel. That is the main wire I ran in all of my fab shops. Another shop tour may be in order once you get some more of that old iron online.
Hello and good morning The 1ga wire is large than the 2ga wire runs backwards on Amp size At 50ft cable the 2ga is rated at 200amp the 1ga is rated at 250 amps
I was only half watching while cooking dinner but when I heard him say this, I came to the comments to check that someone had checked we weren't about to blow some fuses.
I have a 24a and a 60 series sensing unit. There's a 2t and a 4t setting. They touch settings on the trigger. The reason the boards are "smart" is because you can set them for a trigger pull release and it'll keep welding until you hit the trigger again. So you don't have to continually pull the trigger throughout the weld.
That had to be damn satisfying to fix that board for pennies vs. $700-1000! In our throw away society, it's certainly nice to FIX something vs. scrapping it. It appears to be a well built USA made, heavy duty welder that should provide years of further use. Nicely done.
The bar under the lug connectors is a strain relief. It may not be necessary in this application where the cable is actually running to the feeder. But, the work clamp might benefit front having the cable pass under that bar.
Great video, thanks. It's awesome when you can repair something properly yourself for some inexpensive easily available parts, well done. I really enjoy your detailed explanations of your reasons for making certain decisions. Thanks again from Scotland
Excellent job as usual. I’ve rebuilt a couple large heavy duty welders that I got for a song. One was a 30 year old ESAB and what an amazing welder. The other was a Miller 35, one of the first mig welders Miller made some 40 years ago. Those old welders just work. My current welders are an HTP 220 mig and the HTP Invertig, both good welders and take up little space. I really enjoy spray transfer on the mig.
I think that contactor [8:41] is a "definite purpose" one, which is technically intended for HVAC equipment- they are less expensive as a result. It was probably intended to have wires put straight into them, rather than having those terminals, which is why they didn't fit well. I don't know if that makes any difference though. Probably not?
WOW again. You have many similarities with a Swiss Army knife. So you can see that recycling is a great alternative to buying new again and again. Moreover, it is a challenge to get it operational again. Big greetings from the Netherlands.
Hey Van. Great video. I was just wondering if those leads from the welder are suppose to go through that retention loop just below the welding leads? It kinda looks like it.
Nice machine, is it true they can be wired single or 3 phase? Always wanted a power source and a dual feeder like we have at work,with solid wire on one side and gas shield Flux on the other. but a pricey piece. great video, was hoping to see the weld cart build.
Good video. . If there had been a fault on the board I'm pretty certain there is someone out there who could repair it provided that a schematic drawing is available..
Peg a wad of felt around the wire just prior to the drive rolls, this will strip all the accumulated dust and dirt off the wire keeping your liner and welds cleaner. I replace the felt every spool and hood my spool, easy hack but effective if you park the welder for more then a day.
The item needed at 8:42 for the wires on the disconnect is a wire sleeve. Wire sleeves are thin copper and deform to the terminal connector. Edit: Had a typo, it's called a wire ferrule not wire sleeve.
Unfortunately I own a small gasless welder and it’s all about money, I can’t make it positive earth as it’s hard wired but when you can only afford the cheapest welder you can’t expect good welds, it sucks that unless you have money everything is hard, I am 58yo worked all my life but lost everything to the ex, I am still paying credit cards off and can’t work and my only income is a disability pensions due to chronic back pain , Life is hard , I look at these old welders and dream, the old welders are so good but very expensive. Glad you got a great machine there that’s going to last you many year. zGod bless You , regards Andy
Thank you. I saw a cp302 on Facebook for 300 yesterday. I am always trying to be thirty when I can. There are good deals out there just takes time to find them.
Congrats on getting the welder up & running! Please tell me you bought a higher wattage soldering iron and went back over those solder joints on the relay. A cold solder joint like that and that much vibration will bite you in the ass sooner or late and always at the worst possibly time.
Van the inching switch should NOT open the gas valve. I think that arc saftey will not allow the gas valve to open unless you have the welding ground cable conencted and you are actualy welding. You seem to have fixed it with the new part.
friend i bought the same machine with s-52e feeder and i will make maintenance like you is from an auction, i like to know what is the newest torch gun that i can put it?
@@brandonvidal3636 it’s probably an issue w the feeder. I had the same issue. No arc until I replaced the feeder board then it worked. Does the s-52 have a circuit board
@@VanoverMachineAndRepair i found the issue, in the wire diagram is the 16b R2, is a ceramic resistor that convert the 110v ac to 24v ac to activate a 24 v relay, the resistor is burn and I don't know the exact value of ohm and watts to replace it, maybe your welder have it, to know the value
Try to get a rebuilt board. I have a Miller MC 300 VS. The feeder. is a Miller. Four roller feeder. The thing has two guns. you can run one gun at a time.
You don't need to hemorrhage cash to Miller/ITW for a new main circuit board as there are several board repair businesses that will fix your old board. I had my Miller Synchrowave 350's main board repaired in 2022 for about $200.
@@VanoverMachineAndRepair Good to hear you got the CB repaired. I had the name of the service that fixed mine on the cheap to share. There was a comment by another viewer against dual shield wire I can't agree with. While it's probably true not all flux-cored wire used with gas are great, Hobart's FabCO_XL-525 is certainly worth trying out.
If you got tips for that welder but they are too small...just drill one out to test your bigger wire....it just has to be close and a clean hole so it doesn't snag or drag on wire...
Bypass the gas flow delay, will end you up white a pit at the end of te weld. I wouldn't want that. But $700 is a lot of money. Ardunio could be your friend here.

Hello and good morning
The 1ga wire is large than the 2ga wire runs backwards on Amp size
At 50ft cable the 2ga is rated at 200amp the 1ga is rated at 250 amps
My mistake I must have misspoke then the wire I replaced was one size larger than what came off.
He had 1/0 on the welder and replaced with 2/0. Not 1ga and 2ga. Figured out what he meant after I saw the wire size
He meant to say "double ought." I saw the label on the cable and it is indeed double ought.
I was only half watching while cooking dinner but when I heard him say this, I came to the comments to check that someone had checked we weren't about to blow some fuses.
