Thanks! I'd been researching on-line, and watched half a dozen other videos on liner changing...every one had a hex nut on the end of the whip.. which mine doesn't... left me entirely perplexed, until your video pointing out the set screw!!! Got it changed out today and working like a champ. Thanks
I've had hundreds of hours of welding school enjoyed every minute. When I change a liner I just lay the factory one out on the floor and place the new one along side and cut it the exact same length. Now if I can get son to stop rolling the cart over the damn thing I'd be in business.
I'm not much of a welder, but I try hard. When I had trouble with my mig wire not feeding right, I pulled the wire out and ran some compressed air through the liner. Works perfectly again.
A convenient way to clean mig gun liners is to get some solvent in a aerosol can. Brake clean or contact cleaner or similar remove the little spray nozzle and press the end of pressure pak can directly onto the end of the liner. Keep pressure on until the gunk is gone and clean fluid comes out the end works best if the plastic coating extends a good way down the liner. Great videos thanks
Pretty cool video I've got a used Lincoln easy Mig 140 and having feed problems on the old whip, the spiral core is showing up on the very end of the brass Shield gas holes
Thanks Bob! I recently purchased a vintage Miller 200 and every once in a while I'd get some gnarly porosity until, finally, it just wouldn't weld at all anymore. The two O-rings on the end of the whip weren't in great shape so swapped them out but the porosity issue remained. After much hunting, it turns out the gas wasn't making it to the gun at all but instead leaking backward, through the drive and into the wire spool compartment. I pulled it all back apart and noticed there wasn't any O-ring at all on the liner itself so, pulled one out of thin air somehow and slapped it in there (even though it's way too big.) That ended up being the issue but I can't think of where the o-ring could have gone. I looked the part number up for the liner that's in the whip and the product photo very clearly shows an O-ring in there so... ?? Kinda at a loss. I don't really have much time on this welder so I wonder if this is why the guy got rid of it? I mean, if you had seen what he had replaced this old Miller 200 with you'd wonder... why would someone do that!? He was the original owner.. told me he never even put it in the "high" mode. Gave me a serial number matching owners manual that's verges on museum quality along with it.. Anyways, I'm thinking a new liner is the cure to my welders woes. Thanks for the video that shows me how to get the job done!
just did this on my old lincoln wire matic 255 and the old liner screwed into the diffuser at the gun end so I did the same on the install and I just cut the new liner to the length of the old. seems to be working good.
I always blow the gun casing out with compressed air to make sure there is no dust or anything in there before I put the liner in it. This prevents any dust from contaminating your wire and causing more drag in the liner.
Thanks again,Bob! I was wondering what type cleaning fluid/process you use on the liners you clean at the auto shop. Would brake cleaner work? Or would it attack any plastic coating some liners have?
Do I have to replace the mig liner if I go up in wire size? I bought my first mig welder. The MIG welder is currently set up for solid wire 0.6. I want to do flux core .9. I have a 0.9 tip and the .9 feeder wheel. Do I need to increase the size of the MIG wire liner, or does the mig liner that came pre-installed with .6 solid wire good for the 0.9 flux core? What liner should I use for a flux/core .9 (.035) wire?
I have been practicing on 3" stainless steel schedule 10 tig welding and after that I have to tig weld 5 (1/2) coupons all in 6g for a chemical plant test. Really would like to see a video on the schedule 10 stainless and maybe get some tip Nd tricks on welding it. Thanks bob love how you explain things well in your videos.
Hi Bob I have a tweak eliminator I purchased surplus it has 3 X's on the cable hose how many amp gun is this any info would be great it needs a new liner
I have had my lincoln weld pak 100 for 17 years, but didn't have feeding problems until maybe after 16 years of service. I only use my welder a few times out of a year, though. So, if you use your welder daily or a few times a week or a month, you may need to change your liner even sooner. Liners don't cost much, though. i bought my liner this week for $12 and change with free s/h on ebay. Other liners may cost maybe $15 and up, so keep that in mind.
Good vid. Regarding the back end of the liner that connects to the welder, whats the purpose of the threaded cap that sits over the brass end of the liner? I have a Lincoln 140C and I'm using a HTP mig gun. I've noticed that some liners, like Tweco, have an end that does not allow for my threaded end cap to be used. Is it dangerous to use a liner without the threaded brass end cap?
I have a lincoln sp135t with an hot torch lead. If its not straight as an arrow is doesnt want to feed. Pulled the liner out and there's no visible kinks or damage. You reckon soaking the liner would help, if so what do you soak them in?
Bob moffatt , Mine is stuck in the case it has been on this welder a long time. , since I bought it and stuck it in the garage. I'm trying to get it ready to roll now and I solved my feed wheel problem but the cable is sticky . I know very little about this machine other than it's a very old Hobart suitcase style cc/cv. And I run it off my bob cat 225. Anyway the wire feeds great until I put it in the tube. Then it sticks a lot. I tried to pull the liner out and I cannot get it out of the outer liner , is my entire cable shot ? Thanks for any advice you can give. Btw the videos are great. !
What causes my new mig gun to build spatter in the nozzle in a very short time? It also makes a lot of bb's for the gas process. I use mig anti spatter gel and that seems to carbon up in the nozzle as well. Running Argon and CO2 mix with 12 to 20 cfph .035 gas welding wire and proper polarity for gas welding. Can it be the brand of mig wire? Seems most is made in China these days. I have tried a tight gap and a wider one with no change. I have been mig welding for thirty years but used Tweco guns previously. I think in the month of having an HTP gun on my new Hobart Welder I have changed nozzles twice which is about as much as I have changed on my Clarke Machine (180 amp aluminum mig) and my Lincoln 100 Weldpak in total for many many hundreds of pounds of wire over the years I have been at it. Seems I have to clean the nozzle every five minutes or less and the spatter , actually some of it is as far up inside as the diffuser and is sticking hard inside the nozzle to the point it is shorting when the nozzle touches the material! This is new to me and I have no answer for why it is occurring. Thanks for any help you may have. They had no answers to it at HTP. I have ordered a conversion for the gun to the Tweco style diffuser and tips and nozzle to see if that is the answer. When measured the wall thickness of the chrome plated HTP nozzle is .043 while the Tweco measures .073 with a copper finish so I am wondering if it dissipates the heat better and would lessen the problem? Doug
I have the same issue with my tweco fusion 180 mig gun. Inserting the power block is fine. Removing though always cuts the last o-ring. I assume it expands out a little & gets caught up in the gas hole & gets nicked. No worries though. I just bought a pack of 100 o-rings for $5.
Jason, the machine you are seeing in the video is actually the 235, the 215s big brother. It will hold a full size spool and handle a full range of .045 wire. The gun, on the other hand, is from our 215.
@@7soulcraft7 I wouldn't even remember honestly. I also wouldn't recommend this brand anymore. I've tried contacting them with absolutely zero response. The rotary selection knobs are acting all wonky and my welder is almost useless at this point. I legitimately rarely EVER used it. Maybe 10 times in 5yrs. Pretty upset that I spent what I did back then and with hardly any use it now is almost useless.
I know this is an unrelated question, but I keep seeing that long grey machine in the background in a number of videos, and it’s driving me nuts as to what it is. So...what is it?

Thank you Sir.
Love the instruction that you provide, and I do hope that everything continues to be well with you.
thank you for the well spoken and clearly shot video. im new to welding and trying to get my 2nd hand lincoln working correctly again.
Bob, Thanks for sharing. I think they should can your welding knowledge. I view all your videos. You explained and come across so clearly. Thanks
As always Bob great info,I wish we could spend a day together,would be a great learning experience
Bob is going to be doing a TIG boot camp over the summer. Once we have information we will post a video.
Good content and video. Sometimes I've cut something 3 times and it was still too short!
Good timing. I need to do this now. Thanks

Good thoughts. I should have done that.
Good tip. I might be buying a powerimig welder soon. I'm trying to learn as much as I can
@@davidthompson5108 I just bought an I mig200e and was wondering how you like it? And have you had the chance to run flux core through it?
Thanks again,Bob! I was wondering what type cleaning fluid/process you use on the liners you clean at the auto shop. Would brake cleaner work? Or would it attack any plastic coating some liners have?

Would a bad liner cause the torch to get hot, also have some vibration occasionally.

How many years or how much use should you expect to get out of a gun/ liner?

hey bob can you tell me what size allen key you used to loosen the screw cause im tryin to loosen mine none of my keys fit
Gave me cold chills
Watching. Reminded of the catheter I had to get in the hospital
Kinda the same thing :-)
I probably need to do this on my everlast mig welder. I've never done it before.
You don't own a welder. That's why you have one comment and always the same singular subscription.

Is it possible to send the WPS to me in an email?
I will ask the weld test supervisor for a copy
I am a college student and i have to take 4 certification
Blank out any company info I'm not supposed to see and it should be fine.
Ok thank you. Bob, I'm am just trying to get as prepared as possible and every video I've see on mig open root is down hill root
What's it called when you have to apply argon to the back of a weld while welding
back purging
Weld.com thanks man
Just on this particular gun or
sir plz upload tig root position
can u do a 2g 3g and 4g stick video with and without backing
Lengthy but yes, we can do it.
This particular gun
Well great. Mine won't get thru the gun at the end and kinked the new line.
why do they give so much line when you have to cut about 2 1/2 feet of it
👍
silly question. if the old liner was the correct length, couldn't you just measure it against that
You can and that's fine but I never trust that it was done correctly in the first place. I always like to lay the gun out and relax the cable.
Bob Moffatt fair enough point
You didn't show the details at both ends.
what happend to you at 30s?lol
But the real question is: "Who killed Mr. Tig, and what did they do w/ the body".....
Mr. Tig has taken a long needed vacation after the cymbol fiasco; but what of Paul?
What fiasco? I must have missed that part...
