Juba igbt inverter model zx7-200
Customer reply replied 4 months ago
It has a two prong cord on it
Electrician: Kevin, Licensed Electrical Contractor replied 4 months ago

Sorry, but I am not able to locate proper documentation on this model. This is a Chinese manufactured welder and there are a few different welders using this same model number.

I will opt out of the question. Perhaps another expert can assist you better. No need to reply back to me, you will be notified once another expert picks up the question.

Or can you tell me the nameplate data, It's 220V, but it should tell you the amps as well

Ask Your Own Electrical Question
Electrician: Terry Peterman, Electrician replied 4 months ago

It looks like it's 6.5 kva, or 6500 / 220V = 29.54 Amps. You would need a 40A, 2-pole breaker and use #8 AWG wire, and you need 2 hot wires and a ground (no neutral). You need a NEMA 6-50 configuration, receptacle, and would have to put the matching 6-50 straight blade plug on the end of the cable for the unit.

There is no ground wire on the plug end
Electrician: Terry Peterman, Electrician replied 4 months ago

It has blue, brown, and a ground wire as well, no?

Electrician: Terry Peterman, Electrician replied 4 months ago

Just 2 wires?

Do i need to make one off the case or something
Customer reply replied 4 months ago
Just two prong blue and brown
Electrician: Terry Peterman, Electrician replied 4 months ago

I assume then that the unit is double-insulated, just like some of our hand tools that have no earth or ground either.

Customer reply replied 4 months ago
just hook it up like normal 220v but without a ground
Electrician: Terry Peterman, Electrician replied 4 months ago

Send me a picture of the entire unit please

Ask Your Own Electrical Question
Electrician: Terry Peterman, Electrician replied 4 months ago

Is it a plastic case, or metal?

Ask Your Own Electrical Question
Customer reply replied 4 months ago
Metal
Electrician: Terry Peterman, Electrician replied 4 months ago

I would tag on a ground wire and attach to the frame. Use the NEMA 6-50 plug and receptacle. What guage is the wire (approx?) You might get away with a NEMA 6-30, but the one I found online is 6.5 kva

Ask Your Own Electrical Question
Electrician: Terry Peterman, Electrician replied 4 months ago

That doesn't look as large of a unit as the one I found online

Electrician: Terry Peterman, Electrician replied 4 months ago

Do you see anything that says amps, or A? The nameplate data pic you sent is too blurry to see

Electrician: Terry Peterman, Electrician replied 4 months ago

I think I see 18A max, is that correct?

Ask Your Own Electrical Question
Electrician: Terry Peterman, Electrician replied 4 months ago

Then you can use a 20A, 2-pole breaker, and a NEMA 6-20 plug and receptacle.

#12 wire

Ground the frame and run it 220v
Electrician: Terry Peterman, Electrician replied 4 months ago

And I would tag a ground wire on the frame and change the supply cord to a 3-wire, 2 + ground, but if you just want to try it out you could temporary connect without to see if it's any good
