Technical Mig welder tips and their sizes

Wondering if someone can help, I'm looking for some 0.030" mig welder tips that will fit my old Hobart handler welder. The tip that fits has 1/4" - 20 threads and of course I'm all over the internet looking for a number or a seller, but none of the sites that I have found list the thread size. To complicate the search, I'm not sure the stinger head is the one that can on the welder when new, But I do know the tip needs to be 1/4"-20.

 

Do you have a tip currently?
I’ve never considered different thread size/pitch on my wire welders. I have always just used Tweco tips, 3 different guns. I’d always ***umed manufacturers used the same threads/size for all.

 

I also never considered thread size of my tip. Been using the same Lincoln Wirematic 1250 for almost exactly 30 years & couldn't tell ya what size thread the tip is....Sorry!

God Bless

Tips for my Millermatic 250 are ¼-28

 

My older Century which was bought up by Lincoln uses the Tweco tips. Co**** thread and looks to be 1/4 20. I do have finer thread tips I’ve never used so I would guess there Miller parts?

 

My 200 Millermatic uses 1/4" also, I refer to it as a firehose, wish I had paid extra for a Tweco setup.

 

Contact tips are like auto parts; Chevy parts don’t fit Fords. Threads, lengths and diameters are generally different from one brand to another. The part number you want is 379304. The Hobart machines may not be available to all welding supplies, but they are available through Tractor Supply if that is in your area. If not, your welding supply can get an aftermarket brand for you, such as American Torch Tip. The part would be identical in every way. Or online.

 

1/4" - 24 tweco in my Lincoln Electric, if my thread pitch gauge is to be believed.

 

It's been a few years, but the last tips I bought for my Hobart, were from Harbor Freight and they work great.

 

I'm pretty sure that HF has packs of tips with different threads on them and think I have a wrong pack of probably .035 out in the garage. I've got a Lincoln 175.
Hobart is normally sold by farm/ranch stores such as Tractor Supply, Big R / Coastal. That wrong thread pack of tips that I have may have come from Coastal. I'd take a used tip that I know is correct and head to HF or the closest farm and ranch store and check the welding consumables for a match.

 

You do realize you can buy a replacement Tweco whip that fits your Millermatic 200 welder, right? You even have a choice of the whip length.

Tweco is a replacement whip company that offers whips can be bought for most welders on the market.

The tips are whip brand specific, and the tip lengths are used in conjunction to the gas shield cup length.

 

All that!
Just a hobby welder/weldor, couldn't justify the changeover cost when it actually worked, just kind of big and clunky.
A $20k lathe and tooling took all my focus at the time (80's), but yes, I do still cuss the thing.

 

I have a Hobart Beta Mig 200 that I bought new somewhere around 1985. Love the machine. Several years ago I wanted/needed replacement tips and couldn't easily find them so I bought a different brands tips with different threads that were similar in size and simply re-tapped my gun to fit the new tips. Works great and now I can easily find replacement tips. That's what worked for me and my Hobart

 

Thanks to all that responded .
I also have a small Lincoln and it uses a .230" or so dia tip with slightly finer thread than 20 TPI and a Hobart Ironman 250 that uses a much finer thread, maybe a 1/4" -28 thread so three different wire feed welders with three different size thread tips. Kevko came up with a part number so I'll look into that.

 

KevKo, what is the brand ?

Edit, I found them, Hobart number, but that does not look like what I have, those threads are a lot longer and look finer than 20 TPI. they look like the ones that fit my other Hobart.

 

I take the tip off whatever welder I'm using and walk in the store with it. There's usually some identification on the tip if its not burnt off.

Tractor supply /Farm stores have common tips - weekends when the welding supply store is closed or too far away

 

I have an older Hobart Handler as well, early 90's, and I had a hard time finding larger tip for it to run flux core wire. Local welding supplier could order some in, but weren't in stock.

 

I know that 6 mm is .236ish, I'm guessing the "offshore" mig guns and tips are metric.
Makes sense they would be a few thou. under for easier changing.
If using an uncalibrated dial caliper the numbers can be off a bit also.

 

Good point there. That puts another twist on it. The USS/SAE vs metric thing.

Yup, forgetting to hit the zero ****on can throw things off.

 

What is this "zero ****on" you speak of?

 

Guessing a digital micrometer and the "reset to zero" ****on.

 

Someone suggested I look at Tractor Supply so I did, no good They did have many of the .23" thread dia tips but none of the .25". I also e-mailed some welding supply stores and while not all of them have replied yet, the ones that have cannot supply what I need.
I did more research and found out that the OLD Hobart welders had a welding cable/stinger that they called "Piecemaker 14A" and that is no longer supported, including consumables. Could this be what I have? don't know, but i'm going with yes. So my plan is to make a new part that the tips screw into and thread them to a size that I can get.
By the way, DDDenny is right, the ones that measure .23" are 6mm and that is the size I will thread my new adaptor.
Thanks to all that helped out.

 

M6x.75 is fine thread
M6x1.0 is co**** thread

 

I have an old Handler as well, and yes, the gun is Piecemaker 14A. I worked for a welding supply for 40+ years (retired almost 2 years ago). The two largest aftermarket suppliers of MIG, TIG, and OXY/FUEL consumables are American Torch Tip and Profax. Try contacting them directly and see if they have the Hobart style tips you need. It is possible they are no longer made (by anyone), but also possible the companies you contacted don’t want to be bothered with an obviously small order. If ATT or Profax has what you want, you will have to buy a standard package (probably 10) and will likely have to meet a minimum order $ amount which could be $100 (prohibitive for us little guys).

 

Do as you see fit but you aren't bolting a wing to an airplane, you are simply "snugging up" a threaded component that a wire glides through. As I mentioned in post #13, it's as easy as finding a tip that's close then running a tap into your gun so the existing threads are "manipulated" to the desired thread. It's what worked for me years ago, and continues to do so to this day.

 

Proper terminology will probably help in the OP’s search. It is a gun, not stinger, lead or whip. The part the contact tip screws into is called the gas diffuser. The part over the contact tip is called the gas nozzle. Let me check my stash of parts to see if I have extra.

 

Reading reviews some say these guys carry hard to find Hobart parts, they also show tip adapters

I just checked and American Torch Tip website shows the Hobart style contact tip 379304 for .030 wire. Call or email them.

 

The thread is 6MM X1.0 and yes I could have just run a 6mm tap into the adaptor that is on the gun but who couldn't use a little lathe practice? Just a small piece of s**** br*** and two hours and it is done, now I can replace the tips with ones that can be bought.
Thanks to all that looked into this problem.

 

Thanks for the thread, I learned a lot from it.
I’d always ***umed (just by my using) they all interchanged.
