    Default Mganetic clamps vs old style copper clamps what is your preference?

    I was thinking of upgraded my stock clamp from my MM 211 and was looking at the old style copper clamps or the Powerbase grounding magnet from "Strong hand." Any suggestions or preference?

    Thanks!


    Updated 4.16.13: I want to thank everybody for their opinion. It has been extremely valuable. and I have without a doubt taken note of suggestions, experience and the links! I decided on both with quick disconnects. walker, I have taken note of your experience as well and would most likely use the mag clamp for exhaust work.

    You guys are great and I really appreciate you all taking time to give me your input!

    I had a magnetic lamp years ago and threw it away. I like the Tweco style clamp.

    Agreed I changed both my 211 and Syncro 200 over to these. They work well.

    I bought two Twecos for my smaller machines but the Croc Jaws look good too.

    The 251 is going to get one and the 180 SD later on.

    My magnetic ground clamp left a huge dent in my shop door. This happened after beat it off the end of the cable and threw it as hard as I could. In my anger and frustration I missed the door opening slightly. Why you may be asking? This was because it left a huge arc burn on a nearly finished project that then had to be cut out and re-done.

    These are the Lenco version of the Tweco.

    It would depend on the situation. I know for me, some things that I am welding on, I can't just hook a clamp on it and weld. It requires the magnet because of the odd shape or the size of it. I would say it is nice to have both just in case. But let me say this, if you do get the magnet, got the 600 amp magnet. The smaller ones sometimes dont have the holding power and will fall off or give you the arc burn on your weldment for lack of sufficient holding power and when it falls off it will cause the arc burn.

    I stripped the insulation off of about three feet of lead, taped up the ends and wrap it around those unusual shapes then clamp on the ground.

    This came from welding tips and tricks and works great. I know it wouldn't work on everything but it is nice to have around.

    Default Mag vs Clamp

    I have mine set up for both I have a dinse connector and can change if need be. I think part of some peoples lack of a good experience with a magnet is they don't think the attachment point needs to be clean, they think well if it sticks its good.
