angle grinder wolf,
Verified Purchase(What is this?)
This review is from: Wolf 9" (230mm) Angle Grinder 2350 watt - Supplied with Diamond Cutting Disc (Misc.)
Bought this to do some cutting after laying patio slabs. From the very first cut there were bright flashes/ arcing clearly visible inside the casing where the brushes are located. I found this very off-putting as if the machine was about to blow. I researched the grinder on-line and read some other reviews about the same problem. Some ' experts' said it was just the brushes 'bedding in' and to run for around 10 minutes without load. I did this and tried to more cuts but to no avail. I decided to return the item which was a real pity because it is a fantastic piece of kit for the money with a powerful motor. If you can live with the constant flashing and are not put off then I would recommend.

Mr. Trevor Martin says:
arcing where the brushes contact the motor commutator is not uncommon; the reason it is visible is because many manufactures put slotted plastic over this area to let the heat out and so you can see the sparks. It should not be excessive but if you are not comfortable with it perhaps better not to use it.
