mate thanks for your advice, i'll get there in end, I do keep trying..
we all had to learn at some point,practise makes perfecto
mate that why i'll keep at it I know the welder i'm using is old but she will do what I need in end, also now have grinder in hand for cleaning the metal..
If the metal is lightly or is covered in paint I like the abrasive poly type discs such as this from Toolstation; https://www.toolstation.com/abracs-poly-abrasive-disc/p22693 Screwfix sell a similar version and there are copies on Amazon, etc as well.
For smoothing welds, removing thicker paint, thicker rust and mill scale I find the floppy discs useful as there is less of a chance of gouging out your metal with them. Like sandpaper they come in different varieties of coarseness. This is an example I've found works alright; https://www.toolstation.com/flap-disc/p28576?searchstr=flap disc
If I'm removing heavy slag or needing to grind actual metal away I opt for the hard grinding discs.
