Has anyone got any experience of, or comment to make , about the hand held induction heaters that are being offered to the motor trade as a safer alternative to O/A for freeing seized components etc.
Thanks for the replies.
From what I've seen most of the versions on the market are similar to the Snap-on one in that the coil has to encompass or be wrapped around a protruding object. What I am hoping to find is one that can replace O/A in heating up 5/16 and 3/8 diameter counter sunk screws in gang mower blades which may themselves be 5/16 to 3/8 thick and screwed to substantial cast or fabricated carrier (sole) plates .
I may have tracked one down being marketed by Pro-Align under the iHeat brand name - waiting for details but suspect that it will be out of our price range.

I really like that idea and already have the necessary kit!You might do far better on csk screws using a carbon rod and a buzz box ac transformer welder. Earth on the carrier, press the carbon rod on the screw head and the heat will be conducted to where you want it.

The coil on that one looks smaller than the liquid cooled one linked to earlier, too small ?
I did think about them the first time someone here posted about induction heaters a year or so ago but I lost interest / forgot about them until this thread.has no one else thought of this?
yep i think the £5 is way too small! I am going to order one of the bigger £30 units from china to play with
