110v Transformers

Post by Cannyfixit »

Morning everyone, I only have one 110v power tool left I. My arsenal and it’s a random orbital polisher which I use for paint correction on my car,so was wondering .
My transformer is a 3kva and is a heavy bit of kit and was wondering how do you calculate what size transformer I will need if I was to buy a smaller lighter one
Details of the machine
porter Cable variable speed model 7424
120c ac 3.7 A ( Nom3.7a) 2500 - 6000 opm
Type 2
I no other information apart from what I have copied from the label on the machine

I understand what you mean, but is it worth it? The next available size down weighs not much less than yours does, and costs the same price £70 (Screwfix 61847)
Fret not, a forum is a collection of opinions. Above, are mine.


Are you going to be working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe because you don't have a hammer?

theres one of those daft little transformers at my garage. it works fine for smaller tools. hoys its dummy out with my mitre saw but then it is a geet big festool.

the small transformer i inherited it off a plasterer. he used it for his big mixer drill and it runs that absolutely fine. im sure it even runs my core drill too
