When we talk about the circuit, you will typically find coils with 8, 10 or 12 layers of wire wound around a coil or an iron core. The number of wraps affects the speed and downward force of the machine. Well-made coil machines do not have holes in the cord.
Always remember to be careful when buying cheap machines that have opaque insulation because they may hide poor packaging work or fewer coils than promised.
* If there is coil wrap you would like from the Lucky Supply USA website that you do not see on ours, please send us a chat of which style and we can order for you and stock for you at no added charge! Click here
