induction heater

[Mark]

Anybody ever use an induction heater to loosen bolts?

[rupert's]

Yes, not in the mutt but in other things, it is simple, you just have to bring it closer and it heats up ...

Doesn't the bolt, or whatever you are heating have to be fully inside the induction coil for this to work? 99.5% of the the stuck bolts I have dealt with there is no way you could get the head of the bolt inside the coil.

[rupert's]

It depends on the induction device, with this machine you just have to bring the screw close to the part with the white canvas and the screw turns red in less than a minute.
There are other heads for other jobs ... Like detaching car windows for example ...

I just called a parts store, he said the price was $500, so too expensive!

[rupert's]

Yes, it is workshop machinery. 500 is a good price for a workshop. To have it at home and use it once a year, it is a machine with a high price and a very specific utility.
In my work we have this ...

Maybe you can heat the screw with the oxygen and acetylene torch.
All the best

Yes, that's what have used before was acetylene/oxygen torch
