Hi, new to the forum. Great place but much of the info far past my interlectual understanding. I have been looking at the idea of an induction heater for use in my job. I'm a mechanic by trade, nicknamed proffessor screwtop by my workmates :) Snap recently introcuced the mini-ductor II by induction innovations to their line up of tools. http://www.theinductor.com/modules/news/photos/000000002200057.pdf Lots, (read most) of the induction heater projects/DIY plans I have looked at use quite heftly coils for the work coil, obviously to cope with the amount of current that is being driven through it. The mini-ductor II however uses what looks like (in the demo)http://youtu.be/hcVYYVGCt5M rather small coils in comparison to any I have seen. Only 4 windings too whatever size work coil they use. Quite thin too with a heat proof protective braid over the coil to protect it from the heat and shorting. My conclusion from what I have seen in the online demo is that the the work coil is working at a very high voltage/low current. It would be great just to buy one but that would be no fun and at £650 that Snap On want plus VAT. Any thoughts on the subject peeps. Sorry about the feet first first post.
