I do a bunch of cutting of weird stuff 3/8 - 2 inch thick small parts . I can’t believe I waited so long to buy them . I love it . Well if I cut fast the clamps get warm semi hot I can pick them up fine to move them. But cut Quality is low .
If I go slow I can get amazing cut cut quality like CNC plasma love it . But the clamps get hot , I have to use gloves to move them.
How hot is to hot ? Will it lose the magnetic force and break them ?

I had to look up flange wizard... never heard of it.
but the warning is on their website front page.
Warning: Excessive heat can damage the magnets.
Keep magnet block away from sensitive electronic devices.
Keep magnet block in “OFF” position when not in use.

Yea but wondering what they call Excessive heat when talking about an oxygen cutting torch

How hot did you get it ?
How do you keep them from getting hot while preheating and cutting the metal ?
Master Welder
No idea. But hot enough to ruin it.
The clamp was a stronghand clamp with small magnets... I only cooked one out of the 4 little magnets...
my fault, they are only meant for setup .. then removed after tacking.
In your case, just be careful I guess.... who knows how hot HOT is...
it's all good until it's no good.

On the other hand, I have a Mag clamp (ground clamp) on my stick welder.... and it HAS got hot from time to time.... especially if metal shavings get under the magnet.
and the mag clamp still works fine... so, who knows

I have a Mag clamp. Mines is weak, i suspect from heat. Ironically a weak mag clamp gets hot from being weak.
