Say goodbye to gaps, warpage and blow-through when welding along metal joints by getting them ready with the Eastwood Pneumatic Perfect Panel Prep Tool. Our patent-pending design creates the perfect welding edge a 0.062-inch, 45-degree beveled flange. Go down both sides of the edge to properly form them so you can do a full penetration MIG or TIG spot weld. Speaking of which, this air tool also has a hole punch mechanism to create the burr-free holes needed for good butt welding. Less grinding and leveling will be needed post-weld, making the entire piece stronger. A welding edge prep tool helps you get a flush fabrication on patch panels and fender replacement. It works best on the 18 or 20 gauge sheet metal commonly used for automotive panels. Professionals get just as much from this tool as beginners do because it simply works. Watch our short demonstration video above to see the entire panel welding process or visit the Eastwood Garage online. We've been helping the DIY restoration and custom car community since 1978.
