Includes: SK 10 AMP burner with one fixed F9S pen and one extra-flex cord. Do not let the SK's small size fool you. It is packed with the same power and circuitry as the SS-D10, so it is great as a starter unit or as a second burner for the serious artist. So what is the difference from the SS-D10? The SK will accept only one handpiece at a time, making it necessary to unplug and plug in handpieces when changing over, and it doesn't have the extra-low-end temperature adjustment. Other than that, it is essentially the same unit as the SS-D10. The SK accepts all Razertip pens and accessories; with available adapter cords will accept most any make of pen, too. 10 amp output provides the fastest tip-heat recovery in the industry ideal wide-range temperature control: won’t scorch wood at "1" through to "red-hot" at 10 super-flexible adapter cords (in standard or heavy-duty) will accept most any brand of pen indexed handpiece indicator lights can help confirm proper pen and cord operation ultra-stable control circuitry for consistent burns even when turned on-and-off-and-on again removeable and reversible handpiece cords allow use of extra-flex or heavy-duty cords laser-welding technology unconditional warranty covers everything (and we mean everything!) for 3 years on the power supply and one year on all handpieces including fixed tips. Even if you drop your pen and break the tip - it’s covered!
