## Questions & Answers

**Q: Can i use a 7/16 bolt on this clamp instead of the 1/2 bolt**
A: An undersized bolt can be used, but it is important to note that the bolt does not (should not) serve as the primary electrical contact. Make sure your crimped ring lead or lug on the ground wire of your welder makes direct contact with the bare aluminum area of the ground clamp frame. The steel bolt, washers, lock-washer, and nut are only intended to surround that joint and press the copper lug to the aluminum frame, maintaining good electrical contact. If you have any steel between the ground lug and the aluminum frame of the magnetic clamp, it will heat up (just like the part you are welding) and the ground clamp will not perform well (and could have a reduced lifespan).

**Q: I see these come in different amps. How do I pick the correct one? Thanks!**
A: What's the highest amps your machine has

**Q: Has anyone used this on a cnc plasma table? if so does it work well? pros and cons please. thanks**
A: Hello Cameron,
I have a fabrication shop and use it for everything, arc, tig and plasma. On a table I would probably make sure to actually attach the ground via the supplied bolt with this product. I only clamp to it. I guess this might only be necessary depending on the amperage of your table. They state 300 amp so really should no be a problem, I wold just say it might do better bolted. Hate to screw up a long run on the table. Hope this helps son.
Jack

**Q: Where is it made?**
A: Made in China

### ⭐⭐⭐⭐⭐ No mod needed for Millermatic 211-works great!
*by C***B on February 3, 2025*

My welding is typically for smaller steel sculptures made from metal scrap. I have a Millermatic 211. The 1/2" bolt that comes with this Magswitch 300A ground clamp would not fit my cable end, so I went with 1/4 bolt and washers. NO need to modify my ground clamp end for a larger 1/2" bolt. Works perfectly! I struggled to get the standard spring clamp close enough to get a good ground. This solved my problems beautifully. I also put a 1/8" thick x 3/4" x 4.5" piece of steel on it as a handle and to protect the ground cable. Which I really like. Its easier to set in place and remove. I have arthritic small hands and the strong spring on typical ground clamp is difficult for me. I wrapped it all up with 1" wide Howies hockey stick tape. Im sure this could have been less bulky with just tape with out the zip ties but I know it will stay put!
