Induction Heat Vs Oxy-Acetylene

Induction Heat Vs Oxy-Acetylene

The use of induction heating in the workshop is on the rise, so PMM asked Induction Innovations to compare the advantages of using induction heat with the traditional approach of using an oxy-acetylene torch for removing problem parts.


There are some key advantages of using induction heat, outlined below. But first, here’s some key questions to ask yourself:

  • Have you, or a colleague, ever caused damage with a torch?
  • Does removing parts take up a lot of time and would a new solution make your life easier?
  • Do you regularly have to replace parts that you could have kept?
  • Do you need to improve safety in the workshop?

Why is induction heating technology a viable alternative to Oxy-Acetylene?

1.) Using Oxy-Acetylene is risky

The use of a torch in a confined space vastly increases the consequential fire risk – plastics, wiring, trim etc. around the part to be removed can catch fire, causing potentially costly damage. Replacing damaged wiring can be very expensive. By contrast, induction heating is a safer, more reliable, flameless heat, created by high frequency magnetic fields, which heat ferrous metals.

2.) Reduced overheads and insurance premiums

The cost savings from not using Oxy-Acetylene are striking. On average, insurance premiums are 10-30% less (depending on use and insurance company). Added to the average cost of £150 a year to rent a gas bottle and with the majority of parts having to be replaced, the overheads start to mount up.

3.) Works quickly, helping improve productivity and profits

Flexible coils, supplied with the Mini-Ductor, wrap round the nut and heat it in seconds for easy removal. For example, a 19mm nut is heated red hot in just 15 seconds for easy removal. As the flameless heat is localised on the part and not the surrounding area, collateral damage to the part is minimised, so parts can often be re-used.

4.) Most importantly, using induction heating as a viable heating alternative to a naked flame means technicians are safer in the workshop.

The Inductor product range, from US company Induction Innovations, is a high performance invisible heating solution, wellsuited for automotive mechanics. The range includes the user-friendly Mini-Ductor
handheld unit (available in 240, 110 and 12V versions) and the Pro-Max 2kw trolley or work bench mounted inverter.
