TIG High Frequency Unit

"Complete with new Weld Craft torch, inert gas regulator, leads (with quick connectors), hose, full tank of Argon gas and new cups and Tungsten rods. Works great! The whole set up for $475"


from what research I have done is that this is an old montgomery ward machine, but my biggest question is how well will it work with my old lincoln "tombstone" (its 225amp, A/C only) I'm not in horrible need of a tig as I have welded exhaust pipe with that old lincoln (and patience), but i would really like to be able to do aluminum, and to make the smaller stuff easier, and yeah tig looks so much nicer...

appears to be a scratch start unit (I don't see a pedal)

but right now I don't have a couple grand for a good unit, and i don't want to get a harbor freight unit (and this one has regulator, bottle of argon, etc)

so what are you guys opinion on this, is it worth a you know what? if so what would it be worth?

If it'll work with a/c then it should be ok. One thing to watch on those is if the insulation on the cable gets worn, it will shock you. Not fun to drape the lead across your leg and have it start arcing.

lol, yeah I have had that happen with the ground connected to a work bench rather than directly to the work.

the only tig experience that i have so far is with one of these:
THERMAL ARC 161S TIG/STICK WELDER KIT - W1003603 | eBay

and that was just doing some small stainless and it worked beautifully. but its also twice the money and doesn't come with the bottle, which leads me to my next idea, if it doesn't work for some reason, how much would the bottle, torch, etc be worth?

really hoping that somebody who has used one before will step forward.

With the cylinder etc (pics of cylinder would be nice) it's sounds like a reasonable deal. but that setup is not great for aluminum.

You can do scratch-start steel TIG without the HF.

I'd offer 300-ish, keep all the TIG gear and cylinder, then Ebay the HF unit since they go high and keep the rest of the gear for free!
Don't get the idea because you buy something that ya can't horse-trade a bit.

Try posting on weldingweb. It's THE place, along with the Millerwelds forum, for welding questions:

WeldingWeb™ - Welding forum for pros and enthusiasts - Powered by vBulletin

Budget solutions for TIG include Miller 330 and similar units. Use a Craigslist aggregator like crazedlist and hit your area, then ask questions in Weldingweb (and Millerwelds if you have a Miller question). You can PM me too but I don't check them often.

There is lots of stuff out there. READ heavily at the above forums and you can self-educate quickly.

Here's the "canonical Tozzi TIG thread" to get you started:
