Sthor brand flask soldering iron 79366 in a traditional housing with a resistance heater powered directly from a wall outlet. The simplicity of the design makes the device almost failure-free, and with proper care of the soldering iron tip, the soldering iron will serve for many years. The power of the heater is enough to properly solder two copper wires or basic electronics in through-hole assembly technology.

• Power supply: 230V
• heater power: 40W
• depth of arrowhead hole: about 50 mm
• max diameter of arrowhead: 4.8 mm

Dimensions of the soldering iron included with the soldering iron:

• Length: approximately 70 mm
• Diameter: 4.8 mm
• Diameter of the tip of the arrowhead: 1.5 mm

Other dimensions:

• Total length with bent cable: 230 mm
• Handle length: approximately 120 mm
• Power cord length: 140 cm

The soldering iron takes 3 to 4 minutes to heat up to 350°C.

How to take care of a soldering iron tip

The rotors of Sthor flask soldering irons are coated with a material that reduces the oxidation of the tip. Prolonged heating and mechanical damage gradually degrade the protective layer, then the tip quickly oxidizes resulting in problems with melting the solder joint. Instead of melting and sticking to the soldering tip, the tin peens and falls off. A proven way to take care of the tip is to tin it. When first warming up the soldering iron, apply a bit of tin to the tip of the spearhead and remove the excess, for example, with brass shavings. The resulting layer of tin protects against oxidation. It is good practice to tin the spearhead every time you finish a job.

Note

Cob soldering irons powered directly from a wall outlet should have a plug with a grounding pin and should be powered from a grounded outlet. Failure to ground the metal housing of the heater is a risk of electrocution, which at best will end in burns. All Sthor brand flask soldering irons have a grounded plug that is connected to the metal heater housing.
