Reply:So,Here's the deal.The 7' fcAW GUN (K126)??, is setup with a 5/64 liner, tip and drive rollers.I carried it in the shop, hooked the power cable to the negative port on my Invertec 275, ground and volt clip to my metal.Invertec was set on 200amps, and Pulled the trigger, the welder clicked, and the volt dial on the ln-22 shot over and went over the 40volts on the dial.Pic. So,I read this sign.So I turned the welder down to so and so amperage.
Reply:So,at the about 30amps, the ln-22 dial went to about 20volts.The wire fed. there was just enough to feed the wire about a ft.The machine arced and sparked.So,In order to weld with this ln-22, I need a CV power source that I can set the voltage.Is that correct?Let me know what you guys think of it, or if you need more pics....~John
Reply:This is dissapointing.....
Reply:Ln 22 should be voltage sensing and not require CV. is there a CV/CC switch somewhere? I haven't been near one since the early 80s.
Reply:Based on the information available, yours is before the code #7800 so is for CV power source only.(Says it has to be above #7800 and welder has to have max OCV 70 volts with low ripple)http://www.lincolnelectric.com/asset...oln3/im282.pdfLast edited by MinnesotaDave; 07-13-2014 at 10:43 PM.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
Reply:Yeah.My buddy has a idealarc sp200, with mig gun and spool gun.I'll be going up to his place this week, and I'll buy a roll of 5/64 fcaw wire to run in it.What wire should I buy??Anyone guess what I payed for the machine, tweco gun, and stick leads???John~

Reply:Originally Posted by 12V71NR 211 or 212 wire. And the price? 250?
Reply:211 is a good general purpose wire. Kind of a continuous 7018. ive used tons of it on heavy equipment repairs.
Reply:Ok,I'll prolly go to weld air or air Liquide this week and pick up a roll.A 25 lb spool is what fits this machine right??How useful will 5/64 wire be??John (fcaw and big wire noob)
Reply:Im not sure how adaptable your machine is, but the ones I worked with way back used 60lb coils. Yours may may take a spool with a 2" center.
Reply:Oh, the 5/64s wire, 1/4" and up you should be ok. Its some hot stuff, protect your knuckles, they will burn.
Reply:Yes,This machine has a 2" hub, and 8"-12" capacity.I'll buy a spool of 211 and 212.I totally forgot about my ranger 8, it goes up to 25volts.I'll do some testing, and as always, get done pics.Thanks 12v71,Great tips...John.
Reply:Don't worry about the LN-22 not feeding with too much voltage. When the LN-22s first came out, they would only accept 48-volts. When we had to run them on Miller engine drives they would not feed at all! But when you strike an arc they will go into over ride, and feed anyway. We had to get out of the habit of breaking the wire off at the contact tip. No way to feed the wire. You could remove the contact tip, and pull the wire out. Or remove the little ground clip, and lightly rub it on the welder's ground clamp and the wire would feed out enough so you could start welding again.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400

Reply:I don't know if you have enough machine for 5-64 wire. I think 068 would be a better choice.

Reply:Sorry Dave.Been posting from my phone for the last little while.It's kinda slow to....Poor seeing too.Fleetwood haha.CEP,This machine has the 2" arbor.John.

Reply:Originally Posted by CEPIt also has pie pans.
Reply:These are the pie pans that go to my LN-25, pretty much the same as an LN-22. Also some 30-year old .068 NR-211 I found in my dad's barn. Ran this plate in the flat position.

Reply:So,Can I take the pie pans off, and run a 10 or 15lb spool just the same?
Reply:Maybe! I don't know, never tried it.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400I'll see if they fit.Thanks.~John
Reply:Ok gents,Need some opinions.I was on the phone with my lws, and getting pricing for parts, wire, liners etc.Just the .068 drive rollers for my model of ln-22 would be $80.And they can not get a .068 liner for my gun.I would have to buy a $400 dollar k126 gun with .068 liner.A 25lb spool of nr212 was $130.Opinions on the course I should take with this machine.Thanks,~John
Reply:Check this site out for good prices on drive rolls. https://weldingsupply.com/cgi-bin/br...alogs.pl?UNDEFDON'T change the liner! I run anywhere from .045" to 5/64” wire in the same liner.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:If I remember correctly the drive rolls for an LN-25 also fit an LN-22. http://weldingsupply.com/cgi-bin/spi...|1|341

Reply:Might want to check on Pro-fax drive components. If you have a 5-64 liner you will be fine.
Reply:Ok,Great thanks you guys.The guy was trying to tell me I shouldn't try and run .068 wire in a 5/64 liner.Said it would arc in the liner, and maybe weld the wire in the liner.Anyway, kinda shady trying to sell a set-of drive rollers for $80.I'll pull the .045 rollers out of my Ln-25 and see if they fit.Now,the big question is, can I burn 5/64 nr212??I'd be running it on my Ranger 8, which goes to 25v.And is $130 to much for a 25lb spool of nr212??John~ (big wire noob)

Reply:Originally Posted by CEPWhat?! I would never talk to that guy again. That is high for 25-pounds of NR-212. But everything up there is expensive. In 1982 when we built the city of Dillingham's dock. It was considered rude to pick up anything on the bar or table under $5.00. 5/64-inch wire is pretty big, you sure you need that big of wire?
Reply:Isn't your Ranger 8 rated at 300-amps, with 100% duty cycle? 5/64-inch NR-212 is going to run between 200, and 350 + amps.Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:You should be able to use the same rolls for.068 or 5-64. The rolls for a ln25 and ln22 list as the same. I have ran 068 nr212 with my Ranger9 and wished it had a little more oomph. I don't know the output of a ranger 8 is but the ranger 9 is a 250 amp machine.
Reply:Well gents,My helmets off to you.The drive roller are the same as on my Ln-25.The drive rollers in my ln-22, are for .068, 3/32, and 5/64.They had a spacer shim in for the 5/64.I took it out, and now, all I need is .068 tips, and wire.My ranger 8 is 210amps DC, and 225amps AC at 100% duty cycle.So,Does anyone know where tips are for this gun??Its not a k-126.It says---  "M-10102.I'd hate to get taken by my lws.~John

Reply:Those sure look like tips for a K-126 gun. Last time I bought tips for my K-126 gun the counter guy at my LWS talked me into buying tips for a Miller gun. Said they were cheaper than Lincoln tips. http://www.millerwelds.com/products/...ux-cored-guns/Don’t pay any attention to meI’m just a hobbyist!CarlDynasty 300V350-Pro w/pulseSG Spool gun1937 IdealArc-300PowerArc 200ST3 SA-200sVantage 400
Reply:My lws is bringing me in a cpl spools of .068 nr212, and he said bring the machine in to see if they have tips for it.What are tips worth??I'd like to run .045 wire, what should a guy pay for a drive roller for it?
Reply:NR-212 is better than 211 but neither is CVN (impact) rated. Why not try NR-232 or 233 or similar ESAB wires? There are many good options in the .068/.072 range which should work nicely with your Ranger 8.JohnA few weldersA lot of hammersA whole lot of C-clamps
Reply:Here is the part number for .045” drive roll, maybe you can find them cheaper. http://weldingsupply.com/cgi-bin/spi...|1|341

Reply:The Lincoln number for the tip for 068 is KP-2100-1. Tweco tips should work as well.. By the way that is a Lincoln gun.
Reply:Gentleman thank you.I'll get it all set-up and show you all the results.~John

Reply:Well guys,Went down to my lws today and bought a handful of stuff.a ten pack of .068 tips cost $33.$130 for the spool of wire.And I saw my dream machine there too!!!Ranger 8 set on 25volts, dcen negative.wfs maybe 150-200inpmin.Not to shabby.

Reply:Don't mean to be picky. 25-volts seems a little high. Maybe try backing off on the wire speed a touch. Here is some 30 + year old .068” NR-211 I ran not to long ago.
