An Arc-Air torch does the "V" grooving a lot more effectively than a

Had a real "artiste" with the arc-air at the construction equipment
shop I worked in many years a go. He'd groove out a crack, then fill
it back in with the welder in less time than the other welder could
find and put a new grinding wheel on his hand-grinder.

There's probably more chance of you screwing up if you're inexperienced,
though, isn't there?

And more chance of hurting yourself with the grinder if you are
inexperienced.

The point I was making is that someone who is competent with a grinder
might totally suck with the air-arc on their first attempt.

Best wishes,
