Welder question and recommendations

[Desert1957]

What is everyone here who does fab work use for a welder? I currently have a "Hobart 140" but not sure if it's going to handle my 1949 rebuild. I know it will be ok for patch panels and body work, but what about frame and differential brackets etc?

[joedoh]

I have a 220V Lincoln 170T (click heat instead of infinite, never have needed the infinite) set up with MIG. bought it 20 years ago and its still going strong, havent found anything I couldnt weld with it.


how is your Hobart set up? 115V flux? 220V mig? I know some lincolns and millers can run both. if flux, its actually going to be more suited to frame work than body work. if you are doing body panels, 025 or 030 MIG wire will be better than 035 flux, which can leave a lot of residue in the weld. I know guys who LOVE their hobarts.

dont buy something new if you dont need it, if its a 115v flux use it for frame work and if you want to do body just buy a mig kit, it will get hot enough on 115v to do both (dont try to MIG frame work, and dont try to flux body work)

Thanks for everyone's replies. My setup is a 115 volt Hobart 140 with .023 , Argon gas (no flux core). Welding chart under the cover says it can weld upto 1/4 inch with a short duty cycle. I do have a small spool of .030 wire

I have a Hobart 175....underneath I think it's nothing more than a miller... or at least Miller parts interchange with the Hobart stuff...hardly ever run it wide open...only reason I'd want a bigger amperage welder is for the longer duty cycle....
Like Russ says...use solid wire and gas,,,,.030 wire for frame type stuff and .023 wire for sheetmetal...
I've had this welder nearly 30 yrs...well worth what I paid...but I'm currently considering going with a Vulcan 220...it runs on both 110 and 220 ad has mig, tig, stick options....we use these at work , they are a very good welder for the price...

I used to have a 120V Miller, and now I got a 220V Hobart.

Personally i will never go back to 120V unless i just need a small welder again. On anything 1/8" and above the the 220V lays down such a flatter weld since it is able to burn better into the metal.

You can do frames with 120V, and I have with no issues 10 years on. You maybe just have to to 2-3 passes to get the proper weld. Since it can not get the metal truly hot enough for fusion

[edgeleycanuck]

I bought a miller 210 at an auction, I dont know if ive ever used more than half of its potential(not only used for vehicle projects), but what i or others have doesn't matter, you want to know if what you already have bought and paid for will suffice.
I'm not sure if there is anything more than 3/16 thick on our projects( I have a bit of 1/4 only because I had it around)? A suggestion I would make is practice some welds on some scrap peices that are as thick as what will be using on the finished product, even cut through the weld to check penetration. As far as duty cycle goes each weld is really only moments at a time. Penetration is what really is the deciding factor, if the metal is prepped/vee'd correctly more than one pass could work too.
Body parts/light gauge metal, I think most would agree that mig with gas is by far preferable as compared to flux core.

Thanks, this is the kind of info I need.

I'd be leery of the penetration on .25" steel. Look at some videos on welding thicker stuff. Looping beads seem to give more time in a small area and get better penetration. Sort of like a series of cursive lower case E, but circular.

Thank you! That's why I really do like being a member of this forum. You guys have just cleared up the confusion I had over which wire to buy for the start of my new project. The only question left is what gas mix do I need to do the suspension/frame items along with the patch panels?

[joedoh]

let me answer by clearing something up. MIG gas shields the weld and makes it faster and cleaner, but it also needs more current. "mix" is 75% argon and 25% CO2 is the most common MIG, straight argon is less common. anyone who has gotten a straight argon by mistake instead of mix knows you quickly run out of current, welding takes more power with the 100% argon. its the same way with flux and MIG mix, seen in this welding thickness chart with the two processes.



115v flux can actually be more powerful than 220V MIG, seen by the difference in heat settings. MIG (mix) is better for thinner metal, for sure. which is why my answer was to use flux on your frame and MIG on your panels. But if you try to MIG the frame, you will need more power than likely the machine has. Flux on the frame will be plenty though. Sucks changing wire (and output polarity, dont forget to change that between flux and MIG), but its cheaper than buying a whole new welder.

Russ done got you covered .....75/25

Anyone have a dual purpose welder? something that can do mig and tig would be awesome.

I just purchased a Eastwood Tig 200 ac/dc the welder will let you arc weld along with the Tig feature,
but i do have a Millermatic 130 and i use it mainly for sheet metal work with shielded gas and .023 solid wire, i did use it with .035 Flux core and welded in my Flat Out Engineering cross member on my Cameo.

don't really see a need yet to arc weld with the Tig 200 feature yet ? but i guess nice that it does have this feature if i wanted to.

We have started using Vulcan welders....they do mig/tig/stick....at work they are replacing Miller's with the Vulcan's...for the price they are a great welder...

[jocww]

Im still using my old miller 220 challenger 172. its ok. I learned tig on miller and bought this off craigslist still using gold gas. But i do hear the new harbor freight stuff is really good. might get one of their tigs.

no kidding. if i learned one thing today its that I need a ESAB 205ic. NEED IT

Yea, no kidding. After watching this video this ALL in one machine makes everything else obsolete.

love this guy , been watching for couple of years now

I have the Hobart 190. This is a refurbished unit directly from Hobart. Appeared to be brand new. I had heard that many are floor display models which cannot be sold as new, but I cannot confirm.

very happy with my Hobart 190. But I was upgrading from a Harbor Freight model, so...

[MiraclePieCo]

My experience: a good welder (the person) can safely weld frame and chassis components with a 110 machine. I'm a crappy welder so I use a 220 unit. I need the extra amperage to compensate for my bad technique.

BTW, my welder is a Chicago Electric from Harbor Freight - they've really improved them, best unit I've ever owned.

[joedoh]

a basic TIG rig is 2-2.5k. I have been thinking of getting a TIG for a while now. if for 500-1000 more I get a super fancy MIG that learns my welding technique, sing me up.

but later. 2020 has been the year of super spending for me.

[Kevin Mac]

I bought an Everlast multifucntion welder about 10 years ago and has been a good welder. this is the later version of what I bought. It doesn't have mig though.https://www.everlastgenerators.com/p...powerpro-256si

[Myclassic68]

Is the ARCCAPTAIN MIG Welder, 200Amp a good welder?
