4- and 8-inch Magnetic Copper Butt-Weld Backer Set is rated 2.5 out of 5 by 10.
Rated 4 out of 5 by from Awesome product Been using these restoring my MGB. Worth the price. Makes life a lot easier welding. Makes a good backing, heat sink. wish the magnets were larger and stronger.. but they are acceptable. If the surface is not flat, you can clamp them in place Nice heavy pieces. very well made. Everyone in the autobody class I am in borrows them. Once they use them, they buy them. Wish I got a commission from Eastwood!! The peices are great. More shapes (long and thin, or wedge shapes would be helpful for those closed in and hard to reach areas. These are a must have for your welding toolbox

Rated 3 out of 5 by from Needs improvement I had the magnets pull out after getting the copper hot from welding too and the magnets seemed to have lost their magnetism after that also. The copper is heavy and works well to weld against but as has been stated, they don't bend and I find thier use limited. I bought 2 large, flat magnets to hold the plates in place and have also used clamps to hold them. I will be purchasing the flexible wedges for use on fender repair for better contour conformity.

Rated 3 out of 5 by from Seemed like a good idea ... These consist of a nice piece of heavy copper. They works well on very flat surfaces only. It will not conform to surfaces that are not flat so magnets will not adhere to the workpiece. The magnets are held into hole in the copper by a pressure fit. I got mine so hot that he copper expanded and some of the magnets fell out. When I tried to press them back in the magnets broke into pieces.

Rated 3 out of 5 by from a fix for these plates I like others have had the magnates fall out the first use. They also lost their grip during the first use. I ordered some 1/4" super strong ones off line and when they came in I put them in. I also used a center punch to add 4 divots around each side of the magnates to hold them in. So far this works well. Remember to not get them hot with continuous welding.

Rated 2 out of 5 by from THE COPPER WELD BACKERS ARE MADE OF THICK COPPER. I HAVE USED THE 4 AND 8 INCH MAGNETIC COPPER BACKERS. THEY WORKED FINE AT FIRST, BUT NOW THE 4 INCH IS NOT MAGNETIC AND WILL NOT STICK TO STEEL. I HAVE TO CLAMP IT TO THE WORK. THE 8 INCH WORKS GOOD AND STILL IS MAGNETIC.

Rated 1 out of 5 by from needs stonger magnets Got my copper Butt-weld Backer set today and after the first use the magnets became weak. As soon as you start to weld the plate falls off. The metal is completely clean and should hold but doesn't. These plates are a great idea but they need work. Very disappointed especially for the price you pay.

Rated 1 out of 5 by from Poor Magnet quality, Pricey, Used for about 5 mins and the magnets fell out, left unsuable. poor quality and obviously never tested by Eastwood. why would you degrade your brand with this type of poor quality product???
