That would be a great way to unload compressors with aluminum windings!

freonjoe,
Do you know how to recognize which compressors have aluminum windings? Also by 1000 compressors do you mean 1000 large A/C units(3-5 tons)?
I do 300 or 400 hundred a/c compressors and around a 1000 refrigerator compressors a year.

I have a 9 inch grinder & no plasma cutter.
I have found theres 3 or 4 weld spot marks on the side of the compressor, they are horizontal, scribe a horizontal line thru the centre of them, all around the compressor.
Now cut around the outer casing right thru the line. I use a 9 inch angle grinder with a 3mm thick disc.
If its done right... Both ends of the compressor casing will come off the motor with a few bashs from the hammer.
That will make it into 3 parts, top, bottom, inside.
The sides of the weld (top & bottom edges) that may still connect the casings to the motor, they break with the bashing. Since most of the actual weld is ground away during the cut, it leaves the inner motor part to come loose from the casings.
To get at the other part inside the compressor, its not welded in, so jam a steel shaft up there & lift the casing up bash it down onto something hard so the shaft hits the ground while still in connection with whats inside the casing.
That gives it a good jolt & whats inside drops down a bit, keep doing that till the inside part drops out.
When I dropped it onto a steel shaft, I kept missing & bashed the part back up inside it..
Some compressors had a larger weld & I just 'double width' cut there & I also used up some old worn 5-6mm thick grinding disces I had left, doing that.

Wow. I ain't been on here in a good bit. Nice info as always. We love doing compressors here. Other than hauling straight metal out of a holler, compressors and other motors are our best hourly rate. I hope y'all that are using a torch are in a well vented area. Them fumes ain't supposed to be to great for ya. I usually gotta clear the area for a moment after a couple with the angle grinder.
Eat. Sleep. Scrap.
My understanding is that the fumes are phosgene (sp) gas. It will kill you ifr you get enough of it. Never cut up compressors in an un-vented area.

Good to see you back, zak.

I have 10 ton compressor out of a trane unit. I also have a couple other trane/American standard compressors. I was wondering if anybody has opened any up, and if they have copper or aluminum windings. All the other compressors I have opened up have been copper windings.
If your 10 ton Trane compressor is a scroll compressor then it's copper windings. Some of the American standard piston compressors are aluminum windings depending on the model numbers.
