Not much to dislike. It does what it says in the product literature. Switch works smoothly every time. Keep in mind the "sheer strength" is less that the hold strength and the surfaces that it is holding greatly affect the holding strength. Don't expect miracles.

I work as a welder in a small fab shop, and I have found the magswitch products indispensable for my work. I purchased both the 165 and the 400, and use them routinely for set up work. The 400 is too strong and creates too much of a field to weld near, so it is used primarily to stablize pieces a couple of feet from where I'm running a bead.The 165 can be used in fairly close proximity to the weld area, as the field is not as strong. These models are not designed for high heat applications so I have to be careful how close they are to the bead, and how much heat I'm running. I usually work with thin wall square tubing so it's not that much of an issue as the heat isn't cranked up that high. I do a lot of metal cutting and grinding as well, and they help hold pieces when clamps are not possible or effective.The ability to turn of the magnetic field makes them easy to clean. They aren't cheap, but if you work with metal on a daily basis, they are worth the money. Great product!

You know, I debated between 4 and 5 stars for this review. I like Magswitch devices a lot and have several, but the 400 - at least the one I have - just doesn’t quite feel like it has the holding strength I expected. Oh, it’s strong, no doubt about that, but I can break it free manually without releasing the handle. So I’ll probably acquire another at a higher strength for truly heavy-duty needs. Unfortunately, MagSquare prices tend to jump substantially above 400 pounds.What I LOVE about MagSquares is their versatility. Unlike the more specialized Magswitch devices, the squares are general purpose magnets and jigs. Ours are used for everything from utility use, to temporary jigs, woodworking, metalwork, and even sewing! (If the last seems odd, magnetic guides are common sewing machine accessories, but the ones typically used are basically junk.)Watch your fingers! At this strength you can really hurt yourself!

I use this for very specific woodworking tasks, and for those, it works exceptionally well.I used the threaded M5 holes to mount a piece of wood on that can wrap around each side of my bandsaw blade. I use it in this configuration primarily to cut the cheeks on my tenons, but I also use it to clear out the majority of the waste on my dovetails. The reason why I have to use this rather than the integrate stop on the fence (My saw is a Laguna 18 BX, and I primarily use a 1.25" carbide tipped resaw king blade on it) is that this gives me the depth limit right at the blade, and there are times that the tenons are too narrow and I can't use the built in stop of the saw due to the guide post. This is also what allows me to use it to clear out most of the waste efficiently on my dovetails as well as finger joints without cutting further than needed.I also use this when refurbishing old planes. I have a granite flat reference that I put sandpaper on. I then use the magsquare to hold the plane blade (often in very poor condition) to hold it firmly and with even pressure to lap it to flatness and remove any corrosion.I don't use it very often, but for those times that I do, I am very happy I have it!

I have had this for over 4 yrs now and use it at least twice a week. It's is solid and has great holding power in any set-ups on my jointer, table saw, shaper and drill press. The "T" handle doesn't get in the way and is easy to turn it on or off. I actually now have a couple other Magswitch products that work just as well. Don't stew over the cost, it's worth it.

Magnet is very strong. It works really well but it affects the welding arc some being so strong. I would have bought a less powerful magnet if I had to buy another.

I did a weight test with a 1 inch plate of steel and progressively added weight to it untill it failed to hold at 234 lbs. Its a good magnet and is very strong but they just straight up lie to you. If you need a 234 lb magnet with an on off switch then this is for you.

Magswitch makes a great product. We have been using a 600 for a while in the shop with no problems. I ordered two of the 400's and they also worked great.

Por el tamaño y potencia, muy útil, aunque no llega con la manilla que aparece en la foto sino con la antigua, creo que la nueva que la probe en un modelo inferior será buena mejora.

look at all the reviews all was good very strongonly thing I found is the turn arm if on wrong way cant shut the magswitch off it hit the metal then you have to pull it away so it will turn to off. sometime no room to move it away . that when you find out how strong it really is. lol

après avoir acheté bon nombre d'aimants de soudure et avoir été très déçu, je me suis décidé à dépenser un peu plus pour celui ci : Bien m'en a pris, il correspond tout à fait à ce dont j'ai besoins…

Habe bei Umzäunungsarbeiten diesen 400er und noch 2 ander Grössen im Einsatz gehabt. Zwischen 2 Formrohr-Steher wurden 3mm Stahlplatten verbaut.Magnet ist kräftig und hat eine handliche Grösse dafür. 2 Magnete tragen ein 2m langes Winkeleisen 30x30x4mm zwischen 2 Stehern samt angeklemmten Masseanschluss vom Schweissgerät. Magnetwirkung ist allseitig und nach unten.Einzig beim Schalt-Knebel muss man aufpassen, dass der dann noch zum lösen frei gedreht werden kann.Sonst hat man Mühe das Magnet wieder frei zu bekommen. Eine Seite ist länger und kann dann eventuell nicht mehr am Werkstück vorbei. Knebel Funktioniert grifftechnisch mit Schweisshandschuhen gut. Muss zum Schalten etwas niedergedrückt werden.Den neuen Schaltknopf habe ich noch nicht.Bei meinem Schutzgasgerät wurde der Schweisstrom beim Arbeiten direkt neben dem Magneten beinflusst. Ging zum Heften grad noch. Zum Durchschweissen dann den Magneten von der Schweisstelle weg und gut war es.Der 165er ist wirklich ein Winzling und für kleine Werkstücke wie Laschen gut.Der 600er ist schon eine Nummer. Bei eigeschaltetem Magnet ist ein herausziehen von einem zufällig eingeklemmten Schweisshandschuh nicht mehr möglich.Ein/Aus funktioniert bei allen grössen Tip Top. Also kein Restmagnetissmuss. Einsprühen wegen Schweisspritzer nicht vergessen.mfG
