Any comments on this Tig welder

KEMPPI 250 AC/DC WATER COOLED TIG WELDER.

Is it any good? Not a very common brand. How much is one worth in good condition? Can I expect it to handle most chassis and tooling jobs?

[Matt@RFR]

I've never heard of the brand. Do they have a website, or do you have any more information on the welder that you can maybe scan and attach here?

Assuming a good machine, a 250 will weld any thickness steel, and aluminum and mag up to about 3/8" with no pre-heat.

Here are the spec's that I have avaliable. Everytime I look up the brand, the sites are in the UK. Pretty sure it's a euro brand.

Note that this is a 3 phase machine. You won't be able to run it on residential power unless you buy a phase converter, and you'd need a pretty good sized one to supply that machine. You can often find big 3 phase machines cheap on Ebay; they're cheap because they're hard to power and they're heavy enough that shipping costs are prohibitive.

Thanks for the info on that. I guess it'll be no good since it's the 3 phase.

I dunno. It sounds a lot like the Miller Dynasty's with all those features, but like everything else, it might be really cool on paper and suck in practice. Who knows.

It is interesting, though, that they say it "only" weighs 65kg (143lbs), when the Dynasty 300 weighs 90lbs.

Again, comparing it to the Dynasty 300, It's pulling 30 amps @ 250a output 3 phase, whereas the 300 pulls 63a @ 300a...That's a cheap breaker compared to buying a phase converter.

And just so you know, if it is a good machine, there still can be a fairly steep learning curve with all those adjustable parameters. If you're looking to do extreme quality welds, it's good, but if you're just a weekend weldor, it's not worth the trouble.

Kempii is a very commond brand. I'm working as a mechanichal supervisor at a shipyard ( www.gmc.no) Kempii is the only brand we are using. TIG, MIG/MAG and Arc.

I also have a 15 year old MIG myself and its working perfect.

Hi, Cybermars here the welder you've got is pretty high-brow, for some reason they go for more than miller or lincoln, so I would guess that they are not crap. at anyrate things like infinite amprage adjust (not tapped switch) and large duty cycle, as well as maximum amprage obtainable is the key. however a machine could have all that and still suck. the bead (especially hard wire) will let you know pretty quick. good luck,...cyber...

Kemppi is made in Finland and its supposed to be very good (comparable to ESAB which is Swedish). I dont have one but all the people I have talked to that have a Kemmpi is really happy about them.

Not only is it 3 phase but it may be setup for 50 HZ if it is designed to use in Europe (instead of 60 HZ in the USA). Be patient and you will find a good machine at a good price. I picked up a barely used Miller Snycrowave 180 with full argon bottle for $1300 (single phase, 240V / 50A). Remember the gas bottles can get expensive so if you buy used figure that in.
