    IMG_1281.JPG received this from amazon today,nice bit of USA,it's a stronger hold than the usual ones I have & the varying angle ability is great,only disappointment is the magnets being so far from the end,to protect them from heat I guess.

    The main reason those magnets are kept away from the joint is the field generated from them will play havoc with your welding arc.
    It's a good design trust me.

    I have two of the smaller ones and they are brilliant bits of kit.

    I have a milwaukee block with about 275kg pull off force. A serious tool, find an overhead girder and swing off it, it won't come off.

    But stick it into a corner joint and try to tack up with stick and it can drive you mad. It can be as good as impossible to make an arc to both bits of metal within 4-6 inches of the magnet. It doesn't see much use.

    i never noticed that when using the oil arc welder when i was tack welding those 3/4" steel plates to each other as the magnet was on the other side holding the steel in place so i could tack weld it

    How much? And do they have a physical 90° lockingposition rather than just visual?

    No,they only have the locking levers,the increments are a guide only.
    £115 with vat & del.

    I'm often using an oil cooled. If I have it the right way round dc is worse.
    Maybe you're magnet isn't as powerful, or maybe thicker metal helps as often I'm on thin stuff.

    Sometimes the pull is so much that I also struggle with the rod trying to move from the joint to the magnet as well.

    With just under 300kg of pulling force I'm surprised it's not whipping the rods out the stinger lol. :clapping:

    Magnetic plate lifts.
    Good tools if you keep the sheets separate with wood. Not great for picking them up individually if they are on top of one another.

    It probably would if the rods were thick enough to contain enough magnetic material.

    i was using an aldi magnet at the time the adjustable one at rear of the 3/4" thick steel all i did was tack weld it in place then take magnet out

    there was no pull on rod or anything else whilst tack welding the steel

    I find the same on my small Spaldings ones,from outside there not strong enough,however on the inside you can't weld the full length of the joint.
    It would be nice itthis new magnet had contact surfaces further down,as long as you remove it before it overheats,180f,as instructed.

    You're using an aldi magnet which probably has less than 10kg of force or maybe 30 if it's switched.
    My magnet is 275 kg! You would need a winch to detach it from 3/4 plate.
    Like comparing a strimmer engine to a bulldozer engine!
