Strong Hand Tools AGK320 Hole Plug Magnet, Hands Free Weld, Pivoting Magnetic V-Pad Base, Spring Loaded Arm, Heat Dissipating Copper Pad, 5.5" Length

It's a great idea and it works. Makes quick work of welding pin holes and small holes in an auto body. I need something with a magnet and this setup is pretty versatile. The magnets pivot and so does the arm. The arm also extends and retracts. I dont know how long it will last as the copper does get charred but I already feel like I got my money's worth. This saved me a lot of headaches.

I bought the standard version and I’m glad I did. The magnets are very strong and more than ample for anything I’ll need this for. I put this to work filling five holes in a trailer fender. I’d estimate 18GA steel. It worked amazing. No more holding a paddle or using a penny to weld up small holes. This will get a lot of use and I’m super happy with this. Frustrated at myself I didn’t buy this sooner! Haha.

I don’t write a lot of reviews for Amazon, but this magnetic hole plug magnet is simply amazing. I’ve Stick, Mig and Tig welded for years and finally purchased this because I heard it was worth while. Wow! I can’t believe I have gone without using this for years. The copper backing pad does 3 things. First, it provides a backing material to help weld holes and gaps- so much nicer that trying to weld thin sheet metal gaps without- prevents burn through on edges and gaps. Second, the copper provides a conductive area to assist in continuity of welding gaps. When using a gas mig, it doesn’t splatter, spit or jump. It joins the edges seamlessly. I was joining gaps of 1/8” that look amazing with this tool. Third, the copper backing provides a surface area to keep the weld beads from over shooting which helps reduce grinding and clean up. I am shocked at how great this tool is and how I should have bought it years ago. I’m replacing the floor pans on my 1966 Mustang and there is a huge amount of welding, gaps to fill and grinding. I had to share. Really, this is worth the money no doubt.

I gave 4 stars because I have used the tool and it worked. It's just not strong enough a magnet to really use easily.

Looks like it might wirk

Solid product. Performs excellently. The magnetic feet are almost too strong, so it holds in place well. Excellent addition to your welding tool kit.

Works great for filling bolt holes

My 57 Apache truck's previous owner thought fiberglass mesh was a good way to repair a 10 x10 inch hole in the firewall! And of course they butchered the dash with a single din radio, I mean hacked it up! SO...with the help of this little dude, I cut replacement metal and rebuilt it all. This was my "outside" hand and my "under the Dash" hand, holding my metal up as I welded. Can't tell there was ever a repair now. Love it, strong and easy to use.

Excellent product, makes filling in old drill holes in the van easy to fill while reducing the need for another person to hold a copper backing block whilst welding. Strong magnets, advise cleaning back material including under seal and using anti splatter spray on the copper pad before welding.

Handy tool. Magnets are strong. Does what I wanted.

It worked for me to plug up bolt holes with a mig welder.
