There are four sections to this page. The first compare a resistance soldering iron to conventional soldermethods, the second shows free books on resistance soldering, the third contains an extensive collection of video tutorials on resistance soldering and the last an index of our complete series on resistance soldering.
What are advantages of resistance soldering?
There are many!
- Heat is localized at the point where the soldering iron tip touches the metal.
- Localized heating is nearly instantaneous so nearby joints are not affected. The result is that you can make joints that you could not make with a conventional soldering iron.
- Hobby modelers can solder photo etched parts, etched brass kits and other thin copper based metals without damaging them.
- Eliminates the need for a torch. Not only is there no flame or burn hazard, because the heat is localized, there is no oxidation or fire scaling of the work and therefore no requirement for pickling.
- Burn hazards are eliminated because soldering probes cool rapidly.
- Removing enamel from magnet wire is fast and efficient.
- They are particularly time efficient with solder paste. There is no need for flux, pre-tinning, or after soldering flux and excess solder cleanup.
- Material and operating costs are lower.
- If you use flux, you need less because flux activation is higher.
- Solder use is lower because tip pretinning and conditioning is eliminated.
- Power consumption is reduced. While conventional soldering irons are continuously on, resistance soldering irons are on demand units and that demand is typically only 1 to 4 seconds.
- Power consumption can be lowered further by adjusting power to exactly what is needed.
- Soldering iron tips and probes last longer.
- Damage to heat sensitive parts is eliminated. This makes for efficient circuit board repair.
In short these are efficient, on demand units that allow for fine scale and general high quality soldering.
On What Type Projects Is Resistance Soldering Used?
Photo Etched Parts
Etched Brass Kits
Soldering In Positions Or Places That A Hot Soldering Iron Can Be A Burn Hazard
Anywhere You Need Heating Without Damaging Components Or Nearby Solder Joints
Note that resistance solderers are in reality variable power spot welders. You choose the power capability based on the work that must be done.
