No Iron! If you want the 40W iron , order SL540 and save $6!

Model SL-5 is the station that comes WITHOUT a soldering iron. You may plug in any iron and obtain variable heat. It is suggested that you use 40 watt or 60 watt irons. This unit includes a holder funnel for the iron, sponge pad for cleaning the tip and an on/off switch with indicator light.

Very Similar to the popular Weller WLC100 at a lower price!
