Hi. I'm picking up a plasma cutter to use on my bmw. I was hoping it would be ideal for replacement of the wheel arches if I can create a hand guide to follow the profile. It's a good old machine not a new one. Any thoughts? Thanks jed
In theory you should be able to do it. In reality I don't think you will get great results tho. It will help if you clean the panel off first and use a decent guide which keeps the torch height fairly even.
I use mine as little as possible. Good for cutting up splop or thick stuff when theres no better option but i don't use it on bodywork.
Try it away from the car - by playing with current and air pressure, you should be able to get a nice clean cut with no slag. Theres a few videos out there showing how to do it. And its not as though a grinder doesn't fire a whole lot of red hot particles away from the cut . . .
Wouldn't be without mine. A lot nicer, quicker, neater than slitting discs in a grinder once set up. Make something to run the torch along and you will get a neat cut - try it freehand without a lot of practice and it will look terrible.
If its an old, or previously used one, get some new consumables for the torch - they make an amazing difference to the neatness of the cut.
