Customer Comments

  • Wow they still make this? This was my second soldering iron (first was a 60W fixed power firestarter that literally glowed red hot if you left it plugged in too long), and I quickly learned that temperature controlled irons are the only way to go. To start it up, I’d set it to 5, then as it warmed up, had to lower to 4 and around 3 for good soldering, otherwise it would get too hot and oxidize the solder too quickly. I wouldn’t recommend this even if you are on a budget, do yourself a favor and get a nice temp controlled Weller or Hakko, you’ll thank yourself later.

  • I own one of these. Unless something has changed, the power control knob is continuous, not “five-position” as the above description claims.

  • Worth mentioning - this iron is power controlled, not temperature controlled. Think of it like the control knob of a stove burner - you can control how much heat you put into it, but you can’t tell it to go to a specified temperature and stay there.
