If you work on cars machines or anything big and metal sooner or later you re going to run into stuck nuts and bolts.
Diy induction bolt heater.
An induction heater operates by surrounding the object to be heated with a coil carrying high frequency ac current.
To power up your induction heater just connect it to the power supply you have.
New and improved design.
I couldn t get 1 8 tube locally so i settled with 3 16 to test with.
It should start heating.
One switch to turn on the power supply and another switch to apply power to the induction heater.
Then insert the part you are trying to heat up into the coil.
The main disadvantage of this circuit is that a centre tapped coil is needed which can be a little more tricky to wind than a common solenoid.
Bolt buster works in seconds.
These torches can easily spoil the surface around the targeted bolt or ferrous material.
You can heat a 3 4 steel nut.
I was able to get a paperclip to red hot temperatures in 10 seconds.
Diy induction bolt heater.
Link to wiring diagram stl file for 3d printing the handle.
The reason is that most cheap switching power supply don t reach their rated voltage quick enough to kickstart the oscillation of the circuit.
The power supply should be turned on first and then you can turn on the power to the induction heater.
Basically the entire setup acts like a huge transformer with a shorted.
A flameless handheld induction tool to remove rusted seized or stripped nuts bolts bearings gears pins and more.
Well earlier days when we use the manual method or old acetylene torches.
Amon built an induction heater to break stuck bolts loose.
From there i went back to feebay and ordered a box of 1 8 coil.
In this diy induction heater circuit the transformer consists of the work coil and the object to be heated.
Doing some serious reading on induction and coil theory i made a new coil made from 3 16 copper tube.
