A stainless disc attachment used to heat the metal. Use them on thin sheet after welding to remove distortion.

At one stage bosch were claiming they had the lightest one on the market.
Not sure if it still is?

Metabo do a "low vibration" one which is actually about 1kg heavier than the bosch but possibly nicer to use for long periods.
If you just want really light then go for an air powered one. I have got one if you want me to weigh it up but at a guess I'd say it's about half the weight of any of the electric ones.

Thanks, didn’t think about air ones but might be a good option.At one stage bosch were claiming they had the lightest one on the market.

Just had a look at the prices of a air 9" grinder, think they are going to be too expensive.At one stage bosch were claiming they had the lightest one on the market.

I can price my old one up for you if you like
Another option would be a variable speed 4.5" or 5" grinder.
The cheaper ones loose a lot of torque at lower speeds but that might not be am issue for that job?
Better ones are fine, my cordless 5" has full torque at 9" speeds but unless you already have a battery system the air grinder option is probably cheaper
daft question, if it's only for heating up localised spots, why do you need the bigger 9" grinder? 2kW seems a bit (a lot) of overkill especially if power isn't important.? Surely a small grinder with the spinning disc would achieve the same result? at the end of the day it's just using friction to generate the heat, so it's not purely a question of power, more time against the metal will create the same result.

Probably not fast enough to create the heat

I have a 6 inch metabo 150mm and it’s a monster. Would never go back to 4.5 and 5’s again. Barely use the 9 inch grinder other than for concrete
