I was detailing a Tahoe this morning. I was halfway through the detail and polishing with the PC on 6 with the 5.5" orange LC pad with SSR2.5. All of a sudden the pad starts smoking, turns out I melted the center of the pad and the center of the backing plate.

What on earth???

So I continue on with my business and all of a sudden yellow chuncks start flying all over the place. Turns out my backing plate started seperating.

Pics to come, but what on earth is going on???

Feed back please
 
Took this picture off AG's site. But you see those little rivets? Those things actually hit my counter weight on my PC. I have to use a spacer to give it enough room. So you might want to check that. This is on the 3.5" BP. Ive also had a BP separate, but no melting or anything.

Make sure you have the little spacer washer on the PC.
 
I have used backing plates for 6 years....and never melted one...

Some of the causes are a poor extension cord and the machine heats up and the heat transfers down the shaft..the other reason is excessive downward pressure..it bogs the machine and when it bogs it calls for more power causeing it to overheat...

I did a car a week ago and PC'd it for 5 hours and the machine never got hot..I use a 12 guage extensin cord contractor grade made for hi draw power tools...and I also have a Porter cable brand backing plate thats ventilated....and a 3M also...never melted a plate or pad....

Couple of weeks ago I had the 3.5" backing plate come apart on me. The metal part with the rivets separated from the rest of the backing plated and flung my pad accross the garage. AG sent me out a new one so I'm good for now.
 
I had my velcro fail once but never had an exp such as yours...Sorry
 
I had the same thing happen last year with the same pad/backing plate combo. Have not had a problem since getting a new bp.
 
I've melted my backing plate at speed 6 before too. One lesson I've learned - don't exceed speed 5, 5.5 in some cases no matter what. If you can't remove defects, step up to more agressive pad/polish combo.
Switch to Edge 2000 pads (like I did):D
Good luck.
 
use less pressure with the correct pad/polish..you'll be good to go
 
While I have read about this prior, I have never seen it personally. I too would guess it had something to do with speed/pressure but will be interesting to see pics and assessment.
 
If you cant use a certain system on speed 6 with the PC then either you're doing something wrong, or its a bad design/ bad product.
 
Here are some pics:

As you can see, the first issue was the center of the backing plate melting together with the pad of my pad melting. After another panel, the yellow chuncks of backing plate starting flying around as it started seperating. I was able to finish the Tahoe, but couldn't go faster than speed 4.

The PC got hot, but not any hotter than it usually does. I was actually holding it by the head and it wasn't uncomfortable.

Very strange. Guess we'll be getting a new backing plate as detailing is on hold for now!​
