The Witcher features a 4.5watt JEX0 motor with up to 10000RPM output with ample power to push large config needles.  It has a 3.5mm stroke which is suited for banging out lining work or color packing.  Designed with a needle clamp so you don’t need to use clunky rubber bands and features a low tension dampening spring to ease in the needle to skin.
