Singel phase machine with 3phase plug?

Singel phase machine with 3phase plug?

I bought a welding machine yesterday.
They told me that this is a single phase machine.
But itt came with a red 5 pin plug. For 3 phase systems.
How can this be a 1 fase machine.
Now i can not use this. I payed alot for this. And it's frustrating after finishing scool, and getting this machine with this type of plug.

STEL TIG dP 221H AC/DC TIG/MMA

On the manufactory's home page, it says 3 phase. And 20 amp
http://www.stelgroup.it/scheda.aspx?...po=tig&LAN=ENG
But in the product sheet, it says 1 phase.
http://www.stelgroup.it/public/produ...DC_INGLESE.pdf
I can not make this correct. Two different info from the manufactory home page.

But on the resellers homepage in Sweden, it says Single phase. And 16 amp.
http://www.weldex.nu/?category_id=94...211-600065000L

How can this be? Same model, and totally different power systems?

I bought it here in Sweden.

I have read and read in two days about this 3 phase plug. And i can not understand how this machine could ever be a single phase machine.

Please help!
I am stuck with a machine i can not use.

My best regards.

Post a photo of the spec plate on the machine , and we can give a decent answer.

either spam or spam.

It is common for single-phase machines used in industrial settings to be wired with 3-phase plugs for compatibility with the plant's existing outlets. Open up the plug and see how many wires are in the cord and how many of them are actually wired to the plug. If the cord has 4 wires and all are used, it is a 3-phase machine.

The version of this machine that I have seen (sold by HTP in the US) is a single-phase machine. As stated above, a pic of the machine plate would be a big help.

Thanks

i added three pictures.

Two from the nameplate. And one with the plug.

I just don't understand it is a 1 phase.

As i can read the nameplate says 230 volts. That is not 3 phase? Or?

Hello Cracyweld,.

What does the manufacturer's data plate indicate? The plate located on the machine itself.
Does the plate show 1~ or 3~ ?
Phase symbol may be: Ø instead of ~
The data plate may show "1/3" if the machine is connectable to either single-phase or three-phase.

How about specifications for input voltage and maximum amp draw?
Those may give an indication of phase.

How many wires were connected inside the 5-pin plug?

Good Luck

EDIT - The pictures in reply #5 posted while I was typing.
The data plate seen in the center picture indicates single phase at 230/240 volt.
An amp draw of 40-something supports the single-phase spec.

It looks like that you just need a new plug.

[cracyweld]

ahhhh

Now i opened the plug

It's only connected to three pins

It must be single phase then. I think

Hope so.

Thanks for telling me to open the plug.

Maybe now i understand more

But on the manufactury home page. On the picture it says 3 phase and 6 KVA.
It does not fit with the product sheet.

Strange.

Maybe now i can rest. I thought i never could use this machine.

Alot of thanks to you.

I also later gonna buy a generator. But i don't know wich will be a good buy on this machine.

Some one that can tips me on that too?
Not a generator that costs millions Cause i spent all my backup money on this welding machine

Best Regards

This weekend i learned good stuff.
I now learned about these plugs, connections, what the symbols on the nameplate means.

Thanks to you guys for clearing up my questions.

The welding people always give steady answers i also learned.

Also the reseller have helped all they can with shipment and everything else.

I have only god things to tell about this machine buy.

Only thing i wish for.
When one goes to a welding school, we learn to weld. And only connect the machines to the industrial sockets.
Never learn about the symbols on the name plate, or the difference on the 1 phase and 3 phase, and wire connections.

I wish the manufactories and resellers write this info on their products.
Then i could easily know, and understand.

But it was interesting and cool to google on it to. But it takes time to find.
And i did not find info about open the plug and look at wires inside on a 5 pole plug.
You helped alot

Now i know i can use a blue plug instead. For connecting to a single phase generator.

My worries are gone
I think i got me a good machine. But not able to use it before i get a generator. I got no 16 amp at home.
But it's nice to look at though

Thank you guys. Now i will take one beer

Second photo, very bottom left corner, right under the icon of the plug. It says "1~ 50/60 Hz" That means 1 phase, and it can run off of either 50 Hz or 60 Hz electrical mains, depending on what your country has standard.

would you mind posting some pictures of your new welder?
the bottom edge of your welder looks similar to an HTP221..


i looked on the link you posted...
yes your welder looks alot like an HTP221, probably some minor differences, but surely made at the same manufacturer..

[brucer]

after doing some more looking the htp221 and the Stel dp 221Hpa AC/DC are the same models..

[cracyweld]

Whow!!!

Other brand

It seems like it is the same mod.

I looked at this web page
http://www.usaweld.com/ProductDetail...ode=70221-12.5

I am not shure if it has the same functions.
It's much more info on it on this machine on this web page.
On the Stel Group it is not so much info on the machine.

It was nice to see alot of info on a welding machine.

It shur looks like it is the same machine. But i can not compare with this info as there are to little info on the Stel Group page on this model.

Anyway. I think this is one extremly good machine. Both ones

I also think it can be used on a 10 amp fuse when welding with low amp. As i think i will when traveling around for also welding thin materials on cars and houshold. Some industry welding will be done to.. But then on more then 10 amp.

It seems like a perfect machine.
I am quite happy that i bought it

Now. i only need to get the materials to weld with. Both Tig, and Arc materials.
Should be fun to test.

[cracyweld]

Upps.

These two machines seems the same.
But, when i compared the panel. It is not the same.
Not the same buttons.
More button and lights on the other.

So. It is not the same model. as the Stel model.

But i think that both should be a great choice.

[cracyweld]

I have read a little about both.

I think the memory option is only available on the red one. Not on the Stel machine.

I can't find anything about memory on the Stel machine.

That's the difference i found for now.

Stel makes the HTP invertig 201 and 221.

Ahh.. i understand. Nice to know
Thanks for info.

Anyway.. when comparing these two machines, they are not the same.

Best regards

I FOUND IT

Tig dp 221Hpa AC/DC from STEL is the same model as this red one. This have memory option. And looks exatly the same on the panel.
It's a newer mod with improvements.
Uses less amp too.

Nice machine.

I also found a great intro video on youtube on the red machine.

It seems i got my self a great machine.
The one i bought is another than the improved model. But hey... I think i got a great machine still. Wish i had this memory option and less amp though

Enjoy
