If you are a TIG or MIG welder you NEED IT!

Nicely made.
Personally I prefer the 3 legged non-magnetic type. I have used those with magnetic bases but find them less easy to move around than the pure gravity versions like this one.



But with copper legs.

I see a use for both - and the magnetic ones can be used "upside down" - one of the attractions of the magnetic grasshopper style clamp is the ability to attach it on a vertical or inverted surface (ceiling) and have it hold a cleat in place for tacking up.
