Looking at an induction heater

I'm working on a project that would benefit from some localized heat. I'm looking at some induction heaters and can't decide on which one. Random Amazon brand, the " Mini Ductor II" or a bolt buster "BB2-acc" and bb2x-acc. This will be a seldom used item.

Have used several different varieties at work. The Mini Ductor Venom HP is possibly my favorite, although all the hand-held ones seem to work pretty similarly. Size/access can be an issue. With that being said, last week I ordered this unit at the lowest price I could find on the zon for personal home use. Need to do some exhaust work and do not own an acetylene torch yet. I hope its not a POS!

The metal has to be magnetic in order for My Mini ductor to work.
What I was thinking was running short-circuit. If you look at "flameless" soldering, that's how it works--one contact on either side of the piece being soldered. I don't know how that induction heater would deal with short-circuit, but that's pretty close to how it works anyway.

it would just be handy to have a multi-use tool. There are times when sweating copper pipe fittings with a torch can make me pretty sweaty, too.

What about using the coil end in a soldering gun, like a Weller pro? Weller is 260 watt, so might take awhile to get to temp?

It showed up today. There is nothing "Mini" about it. Its rather huge, i'm not sure if the pivot function will be useful or not. I believe it came with 8 coils, no idea on the quality or durability of them yet. Finish on insulation is more "sticky or tacky" than domestic parts I've used. I chucked a random bolt in my vice and a random coil over it was able to get it red hot, after some time. Quality seems decent actually, definitely lesser than Inductive Innovations. I hope the twist lock for the coils holds up. Have seen some issues with both retaining styles after some abuse on others.

Summary: It works! Its bulky! Paid less than 165USD before tax with coupon from random zon seller, about best price I could find. Time will tell if it holds up. Will attempt to put it to real use soon and report back.

Non-magnetic materials can be heated fine with induction. It takes more power to heat them up. Not much I haven't heated with
induction systems.

I held a non magnetic stainless steel screw in My hand while I ran the induction heater. The screw did not get even the slightest bit warm.

Induction heaters have been around for a long time in industrial processes. The machines for even heating small items were quite large. As in thousands of pounds. What you have is tiny in comparison.

Yet I had to replace the non-magnetic ss bolts on the cable connections because they would stretch every five minute cycle at Fermi labs. Went to brass and never had the problem again after first stretch. You can heat many things that you wouldn't recognize as beatable.

I bought a no name brand on Amazon with good reviews. It is a 2 piece system with a separate power box and a gun attached to it by a cable. I liked the gun style for access in tighter areas and having the power box separate allows the gun to be more compact. I have heated bolts to red hot with it. I think the cost was about $200 but would have to look it up.

It typically has to be tuned/specifically built for anything other than carbon/alloy steel and is more of an industrial application type thing. We had one at work and I remember we had to adjust it at some point since the stainless part was no longer getting hot enough. This was so long ago I don't remember the details other than it used a large control cabinet- what we had wasn't something portable you could use in your garage.

I've started using mine in a lot of "just in case" fasteners.

Had the Highlander thermostat housing held on with two small nuts, on small studs threaded into aluminum. Not too rusty but seemed a "little too tight" and I thought the last thing wanted to do on a so-far-successful coolant pump replacement, is to have **** like a broken stud.

Gave it a little heat, nut come a little loose but started backing out the stud. not the end of the world but I just tighten it back a bit until things cooled off and the nuts came off fine.

My favorite tool and the most expensive one I own.
