Hi haikel774
                   This is normal because it passes a large current range of 2 to 4 amp, because the wire diameter used a fairly large, use of resistant 3.3/1 or 2 w.

1x1cm 0.5mm  8LAYER   4M   cat5.
1x1m then wind 17 turns. Use wire with 1mm

 What are the results obtained ?

best time
j.
