Tig welder to purchase.

[Cooper]

Hey guys, I had to save enough money to pay off the wife and now have a green light to get a tig welder. (This matching funds thing sucks, but she thinks I'm buying a $100 welder,,,,so hope I don't leave this page open for her to find. . )

I have the capabilities to run 120/240v so that doesn't matter. I'm still figuring out mig on most of my projects but want the precision and ability to weld alum with a tig. I'm staying local with my purchase as a welder for me isn't something I want to skimp on. Miller/Hobart or Lincoln. I have my eye on the lincoln tig 200. Looks like it's good for beginners but has some features/adjustments for when I figure out what I'm doing.

This is the one I'm looking at, price is fine with me. Hobart one is similar priced but not much options for adjusting settings. Verses the next level that will be up in the $2000-3000 range. I'm only wanting this for welding thin steel sheet, aluminum, some 1/8' steel, basically just for the hobby stuff. My question for you guys that weld (and know what your doing/ or know what all those settings do) is would I be making a wise purchase? Or would I be better off with the more expensive welders? I'm not trying to be cheep but realisticly if I need something welded that matters, like machinery or for work, I'm calling a professional. Input appreciated.

your link brings me to there main page not the machine in question.

You r spot on go as high as you can 240 v is awesome in the long run and knowing you the demand will come very soon. You know how to push the limit Sir. i got this one http://www.lincolnelectric.com/en-us...incolnElectric)
smooth as a baby a$$ K2535-1 " link stupid "

Well i think after watching what you are up to..........you might get disappointed
me thinking you need more "ump" like really soon.....I went from a Kempi PS 5000 similar to this http://www.cottandco.com/en/lots/kem...tig-welder-set I sold it when i left Sweden It sucks. But reg knows what you should get i think. "I did welding for SAAB Aircraft for years and still don't know all of it" "doing a long course that covers all aspects of welding"............That is a life time.

I'm not a pro welder myself. But I own and use a Lincoln 140HD. I weld all my project with it. It works great leaves a clean weld, it can weld aluminum also.

Keep in mind I know nothing, I'm not a welder, and I have no training. I started out with a Miller Diversion 165 TIG(inverter type). They no longer make it as it was upgraded to a 180 I think. It does AC/DC and welds really nice for a beginner machine. I started building headache racks for trucks and it was maxed out constantly to weld 3/16 so I started looking for a bigger welder. I came across a 3 month old Lincoln Precision 225 TIG for sale locally. The guy had it bought it for a job thinking there would be more jobs but there wasn't. Him and his GF were moving and he needed cash. It was literally brand new. I called the local Lincoln rep and asked him what it was worth first and then made the offer. I ended up getting it for $1000 less than retail and it came with a bottle on top of that. It is big heavy welder as it is a transformer type. It has a few options but nothing like a full blown pro welder. More than I need though. The diversion had more than enough stank to weld up toys. I built my boat, Euc and parts of my excavator with it. The 225 does have more power but I rarely use more than 120amps working on our stuff. Keep in mind that buying a larger one will let you weld heavier things and that may come in handy(wheels larger frame pieces ect). I wouldn't take that and go out to buy a 400amp welder though either.lol I have a couple of different torch heads. 150 amp that the machine came with and a 200 amp for larger stuff. Whatever you buy I'm sure you will be welding like a pro in no time. I'm not very good at it really so the only advice I can give is be patient and don't use too much heat!

Thank reg, guess I'm going to keep looking a little bit

How do you figure Reg??!!!

Well then that must be some space age fuser/caulk that's holding my awesome dump trailer and so many others together!!!

I have no experience with welding machines as the only stuff I did was at TAFE on tig and mig when I did a course but what I did with my models was a mix of both and different jobs asked for ether, tig came up best for most stuff but my teacher said if I buy one get a machine that was capable of both as they both have pros and cons and can be just as good after playing around with the different setting, and he also mentioned doing a long course that covers all aspects of welding.............

Cheers Tracy

Reality is you are probably accurate Bo, last time I was thinking about welders Lincoln had a nice ac/dc for 1600$ that one must have changed into the one I am looking at now. It doesn't sound too bad for the hobby. 60% duty cycle, I can run it on the higher voltage, price is nice. I just don't know enough about the settings I should be looking for in a welder that would apply to what I would be using it for. Like welding thin steel by just using the arc, how far into a 1/2" block of alum it will penetrate. How thin of alum I can weld ect. I just don't want to spend the initial funds to find out later you were spot on to start with. But on the other hand I know what I'm going to be using it for and don't want to spend more than I really need to. Most of the local guys I can talk to about tig/mig welding are working on machinery parts or production and don't really weld small stuff like what's used in our hobby. One guy I know welds a lot of stainless sheet metal used for commercial kitchens, know his stuff but never used any of the small welders, just big stuff in the 5-10k range. And it would be nice if I didn't need the hoist to move it !! Lol!! Thanks again for the input Bo!! Saab hu! Never really liked those cars!!! Haha just bustin on ya!!

[Cooper]

Ok after trying to figure out what I need and what I can do without I'm taking your guys advise and thinking the Lincoln 225 would be a wiser choice. Reg, input power is no problem. I would like to be able to weld 1/2" parts together and by reading and listening it's all pointing towards what I was afraid of. A $2000+ welder!! Lol!! This is one of those pieces of equipment I know I can't skimp on and don't want to buy something only to realize I needed something else that I wish I bought originally. That's a heavy little bugger, was wanting something I can pick up and move. Hey I know I can weld up something!! Lol!! Thanks guys for pointing out reality.

[Cooper]

When welding 1/2" pieces does the total girth of the part matter? Is it the heat dissipating into bigger parts that the more amps are need for? This is what I don't understand. Say I have a 1/2"-1/2" part vs a 3' long 1/2" part. Is the penetrating just in weld area or is it more for a bigger part takes more heat to matain welding penetration? Reason is most all the stuff I'm thinking of (that size) will be relative small parts but thick. Not fully understanding the mechanics of needed amperages. And just now realizing that the welder is one part and the heads/torches ect are another expense in tig welding. Like Bo said I don't want to find out I should have gotten a little bigger to start with. I did read somewhere the newer inverters are better for small stuff vs the older transformer types. But as with anything with self learning from the internet I'm trying to sort out what is good knowledge and ignorance. I'm on the ignorant side (just not knowing).
Money pit? Yes , need to have, no, right now I've got more money than brains! Lol!! Slowly changing that ratio

[Cooper]

So if I wanted to run a bead in this corner where pencil is pointing would I need 300+ amps? This is what I'm trying to guage for what welder to buy. This would be the max stuff I would be welding on alum.

[JAMMER]

That 200 amp was good for 1/8 inch aluminum it takes a lot of heat for aluminum and what you are showing would take more than 200 amps I would say more like 300 amps to be safe because you are above 1/2 inch thick and like I said aluminum takes a lot of heat. Ed

[JAMMER]

Cooper question wit all that meat why don't you bolt it together with counter sink bolts? That would save you a lot of grief rather than trying to figure out what rod to use what heat range what electrode weather to use just co2 or co2 + nitrogen there is a lot more to tig welding than with just electric welding. There is a way to weld aluminum with a mig welder also. If I were you I would go and talk to a welder like I did or take a class at a welding supply store like Haun Welding Supply there should be one in your area I am still considering that my self. By the way that Eastwood is in PA. Ed

[RCP57]

I don't know if you would need 300amps but you have to think about duty cycle. I think my 225 at full power has 20% duty cycle or less. It won't build heat quickly enough to weld that thickness properly. To actually get penetration on 3/4" you need an industrial welder. Just bolt those parts together or you will be spending 6k on a welder...

[JAMMER]

Thanks Reg that is one thing I left out Duty Cycle that is how long you can weld at a certain setting . Ed

[9W Monighan]

I would bolt it also. Or, Mig it and grind the weld down smooth. Bring it down to my shop and we can do it for you free.

[steamer]

Cooper, I think this will give you a better prospective of what your dealing with!
It's Lincoln"s site for tips. Scroll down to tip 4 and your get a better understanding of why you need more power to weld Aluminum.
