Different types of soldering irons and other soldering devices produce a range of wattages in terms of heat. Using the right wattage of soldering iron when working with electronic boards will ensure the task is completed properly without damaging the delicate electronics. Using too high or too low a wattage when soldering electronic circuit boards can cause damage. The largest differences between soldering irons and soldering guns is the size of the heat source. Soldering irons have a pinpoint heat source intended for precise work, whereas soldering guns are less precise but are capable of higher wattages because the electrical current flows directly through the tool.
