Tumbler Build - For cleaning plasma cut parts.

My tumbler build has stalled lately as I have been put to work on other more value adding projects.I have nearly got one of them done and have been working on setting up my new compressor and dryer.

For us to be able to power the new compressor I needed to have our power in the workshop upgraded as the sub main that the new power point will be installed into cannot handle the load. We had to upgrade the sub main feed cable from 6mm2 to 16mm2.

Once that was done and we had our new power points installed I built a new shed for the compressor and dryer.







Now I need to mount the dryer on the wall, make a moveable base for the upright compressor and finish plumbing everything to my plasma cutter air lines.

Looks good. While you are at it, consider adding a precooler between the compressor and the air tank. A PWR transmission cooler does the job nicely. Attach it to the belt guard so the compressor pulley draws air through it. Run a copper pipe down to floor level and add an auto drain there before going back up to the tank inlet. That leaves a nice run to ensure condensate runs back to the drain. The air in the tank will be at room temperature and have a lot of moisture removed so the drier will work more efficiently. A hydraulic hose specialist will make up nice flexible hoses to simplify the install. You'll thank me.

Thanks Rod,

I have been thinking about the pre-cooler but out here in rural NSW its pretty dry and I have a bunch more filters just before my airline running to my plasma unit. They seem to do a pretty good job of removing any left over moisture from the dryer and condensation in the air lines.

Got the vertical compressor base and dryer stand made today.


Used some 20mm plate on the compressor base to give it less chance of ever tipping over.

Went to plug the compressor power into the power point and realized the electricians have installed the wrong style power point.

Strange plug.. Did the forgot the neutral in yours ?
Is this 380 in delta config?

None of our three phase machines use a neutral.

This is the power point that should of been installed,


And the motor is 415v wired in Delta.

Now to get this thread back on topic from myself,

Have I been doing little bits and pieces on the tumbler of the last couple of months,

Center wall sheeted,


VFD and control box mounted,


Even though its only half finished it has been doing a lot of work. I use it every other day.

I'm still learning about this 3 phase thing but based on the wiring I've done, the 4 pin is for a 10 amp circuit and the 5 pin is a 32 amp circuit.

Not sure about that, my 125 amp plasma is very much a 32amp drawing machine and it only uses 4 pins.

From what I have learnt is that L1,L2,L3 are the three phases and the bottom 4th pin is the earth. I have been told that the middle 5th pin is the neutral.

It would be interesting to know how they wiring single phase with three phase wiring. I would assume they would just use one of the phases and the earth and neutral but not sure. With the three phases on 415 they are 138.3 degrees out of phase, so I wonder how that works with single phase.

With the 5 pin regardless of amperage

L1 > ( any two active lines ) > load L2, voltage = 415 volts
L1> load >(middle pin)neutral , voltage =240 Volts
Earth remains the same
