PowerBase™ Magnetic Ground - 300 & 500 Amp
(2) 5 out of 5 stars
Added: 05/30/2019 by Eric P.
Works great, love the switch to turn it on or off, instead of having to rip if off a part. Especially helpful when you are tacking. Price was a little high, but seems well made.

I just got this strong hand 500 amp magnetic ground clamp in and have purchased the magtech 300 amp. I didn't like the 300 amp for the simple fact the magnet wasn't very strong on pipe, it will work great for at home. The Strong hand 500 amp is a stronger magnet and when placing it on a pipe in the vertical position 2G it doesn't want to slide like the magtech 300. When welding out in the refineries it is always a problem find a good ground clamp so this was and excellent purchase to add to my arsenal. I would advice against getting a 300 and stick with the 500 amp. The magtech that arc-zone sells in the 600 amp is probably a better purchase because I assume it will have a stronger magnet as well. You want the stronger magnet because usually there is a big 2/0 power cable attached and all that extra weight added it will want to pull itself off the pipe. I may still have to bungie cord it to the pipe but maybe not as often. Over all I think this will be a better ground and can't wait to try it it.
