So, i want to buy a used tig welder

I want to buy a tig welder to teach myself how to tig weld for an upcoming project… im going to put the thing in my garage on a newly built workbench.

Sooo where do i go to figure out a good beginner tig welder, im not opposed to buying used, budget is ~ 1k for the welder…

i know im going to have to run 220 into the garage, how much of a PITA is that going to be? i have access to the basement where all the electrical stuff is, so running it into the attached garage shouldnt be TOO much of a pita…

If you’re gonna do aluminum make sure it has high frequency it make a HUGE difference.

A 220V run is easy if you have the space in the panel.

Finding a deal on good used tig welders, not so much.
Edit: try and find upcoming industrial equipment auctions.

Ya finding a good tig for around a grand is going to be pretty hard

it doesnt need to be GREAT… just AC/DC so i can do alum…

I need to be able to fab brackets/ exhaust stuff and possibly stick some tubing together

I dont mind it being used… as long as its in decent condition and i can learn on it… im not running a shop, i just need to stick some metal together…

There was a decent shop clearout / used tig setup on CL for 1500 not long ago. IOW: keep an eye out on there.

220 is just as easy as running 110 so long as you have a spot for a two breakers.

yea, i saw that today, it was on 8/13

im gonna check cuse/rochester and hopefully toronto for a tig

If you go miller or lincoln your gonna spend alot, even used

I bought a used thermal arc 185 used on here a few years ago, it works awesome. You might want to try to find one of those machines used. I think new they run around 2200. Maybe check out mills welding/praxair on delaware to see if they have anything used.

220V lines are easy to run, the only hard part is manuvering/routing the heavy-gauge cable.

I ran one to my detached garage, and ran one in my dads house to an attached garage. Same as any other house wiring, just another feed wire to hookup; just be safe with electricity as always when you do it.

I’d say Craigslist like everyone else has said is your best bet. Look between Cleveland to Syracuse and you’re bound to find something.

www.craigshelper.com for local CL ads.

Good welders dont pop up on craigslist locally very often, more likely to see crappy stick welders and overpriced migs. I was shopping for a used mig for awhile and found nothing, then just went and bought a new machine. The price of my new machine wasnt far from what people were asking for used units. Who knows you may get lucky and find something.

Kind of seems prefect for what i want to do with it… and 1200 for a brand new machine isnt THAT bad, especially that i can get 10% off via ebay

that thing is a pos

gtfo unless you’re gonna spend $10k

:lolno:

After using our tig with HF continuous and start, I say get one that has the capability to use HF continuous.

:banghead:

A squarewave is nice for doing aluminum, but finding one will cheap will be tough. I got lucky on mine. They’re not really required though if you’re just doing light work.

Link to explanation of benefits? is it just an AC pulse?

^ controls the frequency. Do some Googling on it.

I did, i cant find anything… trying to find a brand name or something…

found this abstract from an engineering journal…

Sir, You can only aluminum weld with continuous high freq.
Each time the Current is switching from +/-, the arc is extinguished…
Which happens 40-800 times per second, so it’s actually impossible to weld otherwise.
If it has an AC setting on the machine, it will have continuous high freq.
Some automatically switch to continuous, some you have to do it manually.

Miller Squarewave machines are great to weld Aluminum on.
Cost a little bit, but they’re great.

Newer miller machines you can run on 110v.
Like the Dynasty 200DX and such.
I’m not sure about the older ones.
Just need to redo the plug on the new guys.
It sure limits your output, but you can still get ~100amps on AC and 120amps on DC for an average 15-20amp service.

Starts and maintains the arc.

Diversion 165 isn’t that bad.
Econotig…
Works, runs on 110.
Miller warranty.
Miller product, so you know it’s going to last for ages.

Just don’t be cheap and buy some Chinese 5 in 1 welder on ebay.
Those are fucking horrible.

I’m sure lowlyoilburner is floating around and will chime in with some good suggestions.
Don’t forget though, a good quality gtaw torch, cords/pedal (unless you use torch controlled), argon tank+argon fill will set you back a few hundred more unless you cheap out on it.

edit:
You can probably find the info here.

I’m too lazy to read it though, seems pretty decent.
