TUXING TXES012 Compressor - Caution danger

[Grezco]

Hello,

I purchased the TUXING TXES012 compressor diretly from TUXING. a 300bar 220V 50HZ Auto Stop Air Compressor.
I added AW46 compressor oil, and connected the power cord to a electrical socket. So far, I haven't seen anything abnormal.

I turn on the compresseur with the main switch on the unit, and the RCCB (residual current circuit breaker) tripped.
This is not an overcurrent problem, but a problem with the motor's insulation to ground detected by the residuel curent device.

I unplug the compressor and take a measurement on the motor. 3,35 Ohm between Neutral and Groud, and 5,6 Ohm between Phase and Ground.
The motor has an insulation fault. There is a risk of electrocution if the compressor is used like this.
I have 220VAC on the metalic body of the compressor.

After a lot of email with TUXING for which he asks me for videos and tests, he concludes to : "If it is working without ground, then it can do it. ". Crazy Answer !

I have requested the replacement of the motor. The answer was "USD179", reduced to USD128 some days later.

Of course, I asked for a free engine replacement. But for the moment still no news.
I ended up making a Paypal claim.

Be very careful with this TUXING product as the wiring is scary to see. Insulation with hot glue. Cable sections that seem very undersized. If the high pressure is made like the electrical part it is even more frightening.

Excellent observation. 
Thank you for taking the time to post.

Please post a picture of the whole compressor what model looks like.

My first observation is that this is material that seems to be cheap. I say "seems" because you can imagine that I didn't run this compressor run very much.
I was still able to increase the pressure in the hose plugged at its end up to 250 bar. But even that was not conclusive because the leak rate is important and I can't keep the pressure more than 10s. But since I can't touch the body without risking electrocution I don't know where it comes from.

For me, buying this TUXING equipment is a waste of money. 

The biggest problem, after telling the customer that he can use this equipment like this, is the total lack of warranty coverage. Even on a risk of electrocution.

Hello,

It seems that the Paypal complaint has paid off.
The seller sends me a new engine. It will be necessary to make a little mechanics. I'll keep you informed.

So I pushed a little more my pressure tests (with big rubber shoes and insulated gloves to avoid electrocution).

And there, it's impossible to increase the pressure in the rifle when the pressure indicated by the compressor gauge shows 250 bar. After a few tests I discover that one of the connections has a solid (undrilled) teflon seal.
This is not much, but it shows once again the lack of test before shipment.

Your 100% correct I have the Dual Cylinder big Compressor it has never worked they refuse to return it and just keep asking me to replace items I have rebuilt this whole thing and the compressor has so many issues in design i can tell you it will never work the way they have made it.



On the Low-Pressure side, there is no check valve so the high-pressure side is trying to do all the work... Well, clearly it cant.

Good report on and documentation of a problem. Should be helpful to many.
