CW-20 Makes 2mm coils
CW-25 Makes 2.6mm coils
CW-30 Makes 3mm coils
NOTE: The coiler winds the coils with the loops touching each other. This can initially give wrong resistance values without first burning in the coil. Care must be taken when first firing the device with a new coil. Carefully pulse the device to bring temperature up slowly so you do not create a “hot leg” and melt the coil. Rake the coils slightly in between pulsing to improve the break in process. Pre burning or oxidizing the wire before making the coil may also help.
Caution: Keep out of reach of small children. Use at your own risk.
