ANSWERS TO QUESTIONS Q1 THROUGH Q56

2-52 A17. It gouges the terminal lug and causes deterioration. A18. The use of preinsulated splices and terminal lugs. A19. It has insulation support for extra supporting strength of the wire insulation. A20. To identify wire sizes they are to be used on. A21. Solder will not adhere to dirty, greasy, or oxidized surfaces. A22. The coating of the material to be soldered with a light coat of solder. A23. To prevent burning the insulation during the soldering process and to allow the wire to flex easier at a stress point. A24. One-half the stripped length. A25. Movement of the parts being soldered while the solder is cooling. A26. The capacity of the soldering iron to generate and maintain a satisfactory soldering temperature while giving up heat to the joint being soldered. A27. Although its temperature is as high as the larger irons, it does not have thermal inertia. A28. The resistance of its heating element increases with rising temperature, thus limiting the current flow. A29. File the tip until it is smooth and retin it. A30. It will overheat and could burn the insulation of the wire being soldered. A31. The heating and cooling cycles. A32. Electronic components, such as resistors, capacitors, and transistors. A33. The soldering tips are hot only during the brief period of soldering the connection, thus minimizing the chance of burning the wire insulation or connector inserts. A34. The strands can fall into electrical equipment being worked on and cause short circuits. A35. It enables the tip to be removed easily when another is to be inserted. A36. Wrap a length of copper wire around one of the regular tips and bend to the proper shape for the purpose. A37. Tin and lead. A38. The solder dissolves a small amount of the copper, which combines with the solder forming a new alloy; therefore, the joint is one common metal. A39. 60-percent tin and 40-percent lead (60/40 solder). A40. It cleans the metal by removing the oxide layer and prevents further oxidation during the soldering. A41. Noncorrosive, nonconductive rosin fluxes.
