Although briefly touching the solder to the iron tip prior to the actual soldering can be helpful in transferring the irons heat to the part. Horizontal deflection was probably disabled, although a very slow sweep would have spread phosphor wear.

Even larger work such as copper water pipes will require the use of a propane torch. Navy Warfare and Radar Systems Handbook. This makes it easier to establish a stable view of a waveform with multiple edges which would otherwise cause another trigger. Also, notice the light above the workbench - also a must.

For adjusting the delay line capacitors, a high-pressure gas-filled mercury-wetted reed switch created extremely fast-rise pulses which went directly to the later stages of the vertical amplifier. Even earlier, audio applied to a diaphragm on the gas feed to a flame made the flame height vary, and a spinning mirror polygon gave an early glimpse of waveforms.
