out of curiosity, I put a amp-clamp on that so-called 6hp motor, it draws 10amps.
5hp takes 26amps.
1 1/2hp takes 10amps.
it's got a sticker on it say 6hp.
I'm betting the amp-clamp doesn't lie

For pressure vessel repair, you need to find an ASME certified repair facility who is authorized to repair and restamp the tank. A place that does boiler and tank repair would probably be appropriate. We had a local shop in Milwaukee that could do repairs.

Is the motor registering 10 amps running or at startup?

10amps running, thats why I called it a fake 6hp.
220v single phase takes about 6amp per HP.

I'm not real up on that but my 3hp band saw likes at least 20 amps at 220 vac.

You're right about the fake HP. Lot of discussion out there as it is just a marketing ploy to sell stuff to the uniformed. Very deceiving and misleading.

I think you need to measure the current draw under load. If the motor is just running on the bench, or just starting to compress the air it is not at peak power. Try again when it is cycling at max pressure.

6hp = 4.47kW = 4470 V Amps
At 120V, that would be ~37Amps

The motor can probably handle 37A before melting down. It doesn't say the compressor needs that much power to compress the air and provide the flow.

I have a 3hp table saw and on a 120V circuit it was always tripping a 20A breaker. When I switched it over to 220V it was much happier.

and that is something you cannot do. there is no such thing as 37amp 110v. 30a tops in 110v.
,, I believe you are confusing 220v amps with 110v amps.
it is about 6amp per HP @ 220v.

Here is the nameplate from this motor, although a moot point with a rusted compressor tank, this proves my point about fake HP.
Notice the prior pic showed 6hp, then read the motor nameplate. there is no indication of HP, it is mum, but it does indicate 15amps, and 15a comes out to (15amp divided 6amp/hp= 2.5hp.) They claimed 6hp but the motor amps only supports 2.5
I did put a ampclamp on the motor and idle amp was 10 and ramped up to 13amp @50psi. I can believe 15a @ 100psi, thats believeable.
But, 6hp is NOT believeable.

I did a internet search on that model# motor, and it came up as 3hp

My new compressor tank is on the way.
Earlier I mentioned about drying the air, getting moisture out of the lines. This kid explains it better than I can describe, and if a picture is worth a thousand words, then this little vid is a good one.
For a small boat like squirt, this may seem a lot of hassle, but a larger boat, the air tools and larger compressor is worth a look, especially when you step up to the 8" DA sander.

Got the new tank put under the old compressor & motor & controls. I just couldn't stand it. It was noisy and irritating to listen to it run.
I have enough of the fake HP crap, and bought a new pump. This one is rated at 5HP. The original was rated 6HP. Notice the difference. And I'm gonna de-rate that down to 3HP. Possibly go to 3HP-three phase and run on the same old 220v circuit.
