Anyone got one of these induction heaters to assist in stubborn bolt removal?

I know they are very expensive so looking to see what everyones thoughts were on these before the money tree blooms.

I spend a lot on the smaller bottles of propane gas but never quite trust the naked flame heat.....

Just trying to convince myself and be able to justify this to the wife.

Last time i spent this amount of cash on anything to do with a car it came with tyres and 9 months MOT....

Thoughts?
More realistic suppliers?

You'd want to have a lot of stuck bolts for that price...

Vevor do knock-off copies of Sealey tools, there spot welder was quite good, capable of doing the job at 1/3rd the price..

I just split the nuts with a nut splitter or cut them off.

 

those tools are great if you are in a time restricted environment.

An older stick welder can be used. The one time when sticking the rod is actully good.

The induction heating principle is excellent and these "coil" style of heating elements are good for getting into difficult corners when the use of an open flame is not an option, maybe the close proximity of rubber components or say fuel pipes limiting your approach. They have more uses than just removing rusted up nuts/bolts, using the flexible coil aids with both bearing fitting and removal, exhaust pipe joints and things like ABS sensor inductor rings, their uses become more evident the more you use this tool. I have found the service life of the insulation of the "coils" is shortened if the "heat" is applied for too long a peroid in one shot, shorter bursts of power, repeated once or twice being a more desireable, giving the same ultimate effect, the heat coils have to be viewed as consumables.

It is really "horses for courses" you have to realise their limits and the open flame may need to be used on occasions.

Their advantage is of course you do not have bulky and perhaps, in the wrong hands, dangerous flamable gas bottles stored in your workshop and the training in use and insurance costs are much less.

There are many different makes on the market with a wide range of costs, but I suspect the lower priced units may not have as good a duty cycle as the more expensive ones.

I have used this type of tool for many years, and have a larger water cooled unit which is very successful for the really difficult tasks, but these units come in at a premium price but in saying that I would not be without the oxy/acc torch.

Summing up excellent tools, safe in use and they have their limitations.

I used one of these recently to remove a pinch bolt on a ford in order to change a front coil spring and it worked really well, lucky for me my brother in law owns one and loaned it to me, they are a lot of money for occasional use though, working in a pro workshop I imagine they would soon pay for themselves.

There are cheap Chinese  copies for sale online for under £200 which are apparently quite good.
