Weller Tip Care

• Weller solder iron tips are use special platings and should never be filed or abraded. The metal plating of the tip allows for proper heat transfer and solder wetting, which will be compromised if the plating is damaged. Tips should always be tinned before first use and before the iron is shut down after use. Tinning involves the coating of the tip with a small amount of rosin flux solder to remove surface oxidation and prevent it from forming during storage. During use, and before tinning, Cooper Hand Tools, manufacturer of Weller irons, recommends that the tip should be wiped on a soldering sponge lightly dampened with distilled water. The sponge removes excess solder and component contaminants that may accumulate during use.
  
  

Iron Wattage

• All soldering irons transfer sufficient heat to melt solder. Iron wattage ratings dictate the iron's ability to recover heat after it it transferred from the tip to the solder and work area. Weller makes low-wattage irons, from 12 to 25 watts, that are sufficient for most electronics and wiring work, and help prevent electronic components from overheating. Mid- and high-wattage irons are used for heavier specialty work, such as jewelry and stained glass work, and are not suitable for general soldering.
  
  

Solder Type

• Rosin flux core solder is the standard for general electronic and wire soldering. Although lead-free solder is available, 60/40 (60 percent tin, 40 percent lead) solder is still favored by hobbyists. Solder comes in a variety of gauge diameters, with 19 to 21 AWG (American wire gauge) a suitable diameter for general solder work. Thicker solder requires more heat application time that only higher wattage irons provide and should be avoided.
  
  

Accessories and Tools

• Every solderer should have a few helpful accessories. Weller and other manufacturers offer solder iron stands that help protect the tool and tip from falls, keeping components and body parts safe from accidental burns when the hot iron is idle. Holding jigs for wiring and components are especially helpful and enable both hands to be free to perform soldering work. Protective eye goggles or glasses are important, as molten solder can spatter without notice. A ventilation fan is sometimes necessary when working in close quarters, to help dissipate unpleasant and unhealthy solder fumes. Wire cutters, wire strippers, and a selection of screwdrivers and pliers will come in handy for disassembling and reassembling of components.
