Match the coil shape and diameter to the ferrous part. A close fit transfers energy efficiently.

Induction heater vs gas torch
Two heat sources, a fundamentally different way of working.
In practice
Why workshops choose controlled induction heat
A gas torch heats with an exposed flame and spreads radiant heat across the work area. An induction heater creates heat inside a suitable ferrous part, allowing more local and repeatable work.
Induction does not make every job risk-free and it does not replace every torch application. It can, however, reduce flame-related preparation and give the operator immediate control over when heating stops.
- No open flame at the point of work
- Local heating of suitable ferrous parts
- Fast start and immediate stop
- Interchangeable coils for different shapes
A controlled working method
Compare the method, not just the maximum temperature
The relevant questions are where the heat is generated, how precisely it can be applied and what surrounds the component. The table below helps determine which method fits the task.
The correct coil, controlled heat and a short inspection make the difference.
Start with the lowest practical setting and monitor the part. Avoid unnecessary heating cycles.
Switch off before changing a coil, allow hot parts to cool and follow the instructions in the manual.
| Criterion | Induction heater | Gas torch |
|---|---|---|
| Heat source | Inside a suitable ferrous part | External open flame |
| Control | Immediate electrical start and stop | Manual flame and gas control |
| Working area | Local, determined by coil and part | Radiant and convective heat around the flame |
| Best fit | Controlled workshop heating of ferrous parts | Tasks outside the induction material or access range |

Frequently asked questions
Is induction always safer than a torch?
It removes the open flame, but hot parts, electrical equipment and heat transfer still require training, inspection and PPE.
Which method heats faster?
On a well-matched ferrous part, induction can heat very quickly. Actual time depends on mass, coil fit, power and the required temperature.
Can induction heat non-ferrous parts?
Most iDuctor applications rely on ferromagnetic material. A torch may still be required for materials or processes outside that scope.
