How to remove rusted, inaccessible exhaust bolts

Removing exhaust bolts is often a lengthy, difficult and frustrating task for motor mechanics. The nuts securing the bolts rust easily and as they are usually placed in inaccessible areas, it makes it very hard to remove them.

However, the Mini-Ductor® II + (MD800P) handheld induction heating tool, uses invisible heat which heats ferrous metal (containing iron), and some non-ferrous metal parts in seconds. This allows all types of adhesives bonded to metal, bonded with thread lock compound and seized hardware to be removed and released much quicker and more safely than by traditional naked flame heating. And there’s no costly and time consuming damage to surrounding areas.

Why use induction heating to remove an exhaust bolt instead of the naked flame method?
