Watch Us in Action Repairing Glasses in the Lab
Electric soldering systems are powered with a heat source provided by an electrical current. An electric soldering unit consists of a base providing heat source, a carbon stand with tapered carbon, an alligator clip and a pedal to control the heat source. This unit can produce up to 2000˚ F with a maximum wattage of 1320.
This method requires flux and solder and will solder most metals except for titanium, nickel and related alloys. This method also radiates excessive heat, which will burn off finishes approximately one inch in diameter within the immediate area treated. If the frame has a metal plated finish (gold, silver, copper etc.) it may be polished and re-plated leaving a close to seamless finish. However, if the finish is a colored finish, acrylic paint is usually used to try and match the color. Please note that this finish is not a permanent coating and will eventually begin to chip off with time, exposing the metals true color (usually silver or copper).
Some of the first repairs served a functional purpose and were very noticeable. Through the years technology has developed many methods and techniques of soldering and welding to repair eyeglasses and sunglasses. Below are other methods and technology available that offer everything from functional solders on basic metal frames to virtually unnoticeable meticulous welds on practically any metal frame including titanium.
