brilliant kit!!!especially for cutting out rusted area,s you can just cut a new plate thats roughly the shape you want,
fire up the plasma cutter and cut round it on the car to remove the rusted out piece, then weld the new bit in exactly!!!
saves hours of slog!!!
You get a much better weld if you grind the plasma cut edges back slightly, which means that technique doesn't save much. Although I did the front N/S side floorpan, jacking point and inner sill on a mate's |Triumph 2000 that way, having cut the whole lot out of another car. Just needed some carefull trimming and the entire lot went in one piece.
They're great for doing sills; two straight cuts along the top and bottom, drill out the spot welds with plenty of room, and fit the new one. Quick, easy, and quieter than any other method.
They're not good for multiple layers of steel though, you get a very poor, interrupted cut.
It's well worth ensuring that your air supply is dry and filtered; you get a better cut and the tips last much longer.
