Induction heat frees a seized fixing without a flame. The coil puts energy straight into the steel of the nut or the bolt, so the fixing comes up to temperature while the paint, the loom and the plastic beside it do not. That is the reason to own one, and it is why the tool sits in a workshop rather than a foundry.
Power output decides what mass of metal will come up to heat and how fast. The range here runs 1000W on the Sealey VS240 through 2000W and 2300W, then up through 3700W single phase to 10kW at 400V three phase and 13kW and 18kW on the Sykes Pickavant systems. A small handheld tool will free a brake caliper bolt; it will not heat an axle nut on a truck. The KMi Heater ladder covers the middle of that span at 1.5kW, 1.75kW, 3.2kW and above.
Supply voltage is the constraint that comes with it. A 12V machine works off a vehicle, 230V covers most of the range, and the larger systems need 400V three phase which has to exist in the building before the tool is chosen. Power in kW is stated on 14 of the 25 lines and voltage on 16.
Coil fitment is the third decision and it is the one that gets overlooked. The coil has to suit the shape of the fixing, and a machine without the right coil does nothing useful. Coil kits carry the common forms, the Sykes essential kit holding eight. Liquid cooled and inverter bodies cover continuous work. Fitting questions go over WhatsApp on 07754288583 with a photo of the fixing. A 12V machine and a Speedline body sit at the portable end for work away from a socket entirely.
