Default A Little More Cheap Induction Heating Power

I am in the process of upgrading my 1800 Watt ZVS Induction Heating system to 2500 watts. Still not an "industrial" machine, but it has a number of practical uses in my home shop. In this video, I discuss my plans to make the change:

Man you're having fun designing this induction equipment. I wish I had contacts at the induction company I worked for. I'd get you a tour and you could chat with the designers and likely let you run some 10 to 500kW equipment.

I worked for IpsenLab and Ipsen Industries in Rockford Illinois back in the 1960's. At IpsenLab, I managed the recently formed vacuum heat treating department. In the bay next to it was the induction heating department, which had one 25KW unit at the time. So I did have a chance to see it in action. It was a one man operation and that guy was an artist at coil design, as far as I am concerned.
Back then, the companies that built commercial radio station transmitters often sold induction heating equipment, too. Almost the same machines, just a bit lower in frequency.

I currently work for a heat treating company and use 3 different size induction machines for heat treating and induction brazing work. We have a large selection of coils but i still have to make a custom coil from time to time. We have a lot of vacuum furnaces, a few are Ipsens . I do a lot of vacuum brazing work. Interesting work.

My 2500 Watt Induction Heater is now up and running.

The video of the "improved" setup and a bit about operation is here:

More upgrades to the 2500 watt ZVS induction heater. I think I now have a heating machine that can just be plugged in and used as needed.

This will be my last post about this device, for a while, at least.

Lotsa water over the dam.
Continuing to work with both the 2500 watt induction heaters and the 1000 watt unit. melting copper, adding frequency meters and annealing some more cartridges as I mess around with different coils.
Not too sure how many of you are interested, but I don't see a lot of activity here lately, so I hope you don't mind.

Very cool, have always been intrigued by these systems. They have so many applications and definitely remind me of some scifi stuff from the old movies.

Another small scale induction heating video.
This time I summarize the work coil making process that I use:
