Process Verification over Equipment Calibration for American Beauty Soldering Tools

It is important to understand that process verification and equipment calibration are not the same and that some types of equipment do not require calibration but may still require the development of procedures for accurate process verification.
We are often asked questions relating to calibration procedures for the various tools and equipment that we manufacture. These questions are usually asked as a result of the calibration requirements that are specified in many quality assurance program directives. The equipment that we manufacture can be accurately identified as NCR (No Calibration Required) as there are no features within this equipment which allow for calibration.
Many quality assurance programs will alsorequire the development of written procedures to outline accurate methods of verification that can be utilized to monitor the various processes that may be used for an application. Process verification can be accomplished with our equipment by knowing what measurable, variable attributes exist for the specific soldering application being reviewed.
When you are developing the process for any application it is important to identify attributes which are variable in nature that can have a direct effect on the results achieved. Once identified each of these attributes should be measured prior to and monitored during the process development in order to determine and establish an acceptable tolerance level for each of them. The information collected should be well documented in order to help establish the appropriate verification steps that can be followed to monitor the actual process once the development steps have been completed.
Time and temperature will be the two primary variable attributes for you to be concerned with when developing a process for applications using the type of tools and equipment that we manufacture. For the purpose of this document, time will be referred to in two ways; dwell time will refer to the time that is required to heat and flow solder to complete the solder joint, while idle time will refer to the time allowed between solder joints (from the completion of one joint to the beginning of the next) to recover thethermal loss from soldering irons and solder pots and to dissipate the heat accumulated in resistance soldering handpieces.

How to select the correct soldering iron tip: The Important Factors

A guide to choosing the most appropriate tip for your intended soldering application

The soldering iron tip is the part of the iron that is used to transfer heat from the element to the work pieces that are being soldered. The size, composition and configuration of the tip being chosen should be determined by the requirements of the intended application and by the work environment that it will be used in. There could even be rare instances where a custom tip may be desired.


Choosing the correct tip will greatly increase your chances of creating a quality solder joint. It is very important for you to match both the tip and the iron to the soldering application that it will be used on. It is always a good idea to make sure in advance that the desired tips size and configuration are readily available for the type of irons that you have chosen to use. Always remember that a good quality solder joint is rarely achieved by using improper, or inappropriate tools, materials, or equipment.

Creating brass models from scratch using resistance soldering



Bob Connors called up one day and asked if “American Beauty” resistance soldering tools could be used for building a 1/16th scale brass model of a soil finisher. His intent was to use (primarily) 1/4″ Brass bar stock for most of the frame-work and knew that an intense and localized heat would be required for soldering this type of mass together. He needed to be able to heat and solder each joint quickly enough so no previous joints could get hot enough to de-solder. Bob knew this was going to be a real challenge because brass is such an excellent conductor of heat. He sent us a schematic design of the soil finisher and we began to discuss resistance soldering equipment and process recommendations that we felt would work best for his special application.

After our initial discussion regarding the high thermal requirements and the accessibility of the intended solder joints, we agreed the best place to start would be the Model 105H9 High Capacity Probe System, with the addition of the Model 105358 Industrial Pliers-Style Handpiece. This worked out very well and as Bob continued working on this project we had some follow up conversations regarding additional soldering tools that could be added to increase the soldering range and capabilities needed to move forward with this project. This would include items like the Model 105227 Industrial Tweezers-Style Handpiece and the Model 10573 3/16″ Carbon Probe-Style Handpiece  for greater accessibility and attaching smaller component parts. As Bobs new resistance soldering system continued growing to meet his needs his 1/16th scale, highly detailed soil finisher drew ever closer to completion.




We were excited to receive Photograph updates showing Bobs progress as his soil finisher slowly came to life and are now happy to be able to share this project and the final results with you.

Trouble shooting a 100 Watt American Beauty Power unit (Model 105A3)

Andrew G shared the following:

I have a 100 watt resistance soldering power unit (Model 105A3) that just quit working. I would like to know if there is a fuse that is internal that could be the problem, or is there any component that usually goes on these? I have had my system for about 5 years without issue. I have a pretty good grasp on electronic theory and would prefer to fix the unit myself. Any advice you can give me will be appreciated.
