Here is just a brief summary of what the V3 or V4 deep induction units are definitely NOT about in truck/commercial vehicle workshops or in vehicle construction: “replacing the open flame”. If you only want to use an induction device to imitate what an experienced mechanic does with an oxy-fuel torch (when nobody is looking), even the cheapest induction devices are far too expensive.
This is about depth of effect, about surface temperatures that don’t run away and therefore ultimately very often about clever and quick problem solving WITHOUT ANY HAPPINESS.
