I am a 15 year old boy living in rural Devon UK and wish to have a arc welder. But my Mum says it is too dangerous if I have been properly trained. I have already done some arc welding with a neighbor so has my Dad. I have also looked for a course for arc welding but there all aimed at people who wish to become professionals and too expensive.
How can I persuade my Mum and Dad to allow me to buy an arc welder?
