Air in tank

the air bleed for the tank is not allowing the air to come out as the fuel is going in. Reduce the flow rate at the nozzle to allow that air out past the nozzle.

What kind of air compressor do you need to run a plasma cutter? (how many psi, gallons, volts... and any other info...?)


You will need at least the following:

25 CFH at 120 PSI
30 gallon reserve tank
220 V single or 3 Phase (that depends of your voltage available at your shop/home)

For cutting: set your plasma regulator to 75 psi.
For Gouging: set your plasma regulator to 65 psi.

That's all.

Hi, Is there of clearing the drain hole from the back of the fridge? Mine is blocked and so water is condensing and settling under the salad tray. Thanks

a little air pressure works the best. if you have an air compressor or a portable air tank, usa a blower nozzle. if you can regulate the air then turn id down low, like 15 pounds or so. stick the nozzle in the drain opening inside the fridge and wrap a rag around the nozzle at the drain opening to prevent blow back. give it a quick burst of air and it should be unblocked. if not then give it a little more pressure. after its clear then pour a little bleach water down the drain to kill the slime . good luck

The fan you hear is the cooling fan for inverter.
The air pressure is delivered by the air compressor, through the air filter/regulator device.
Check what is the pressure of the compressor, and the regulated pressure on your pressure gauge (if you have in the front, or may be in the rear of your cutter).

When air is hooked up it blows the air regulator and all the air blows out valve very little gets to safety light comes on on front of machine and it will not work

Air pressure should be no more than 90#s. If regulator cannot handle at least 125#s . Get a new regulater. Sounds like this regulator has a blown diaphram.

Pressure washer has no pressure

Try and back flush the washer..Take spay nozzle off washer and back flush with hose...If any kind of sand or deposits get into the Pump it will hold pressure valve open not letting it build pressure.after back flushing hook back up washer and before you put spar nozzle back on or start washer turn water on and make sure all air is out of washer..hook spray nozzle back up and hold it open with washer still off.when you see that there is no more air coming out of washer start it and you should have pressure.Hope this helps you and have a great day!!

Plasma Cutters support

In this process, an inert gas (in some units, compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the
