A flight from the Landing. Gearâs perspective. Understanding your Twin Cessnaâs. landing gear is a key to safe ï¬ying as. well as controlling your maintenance. costs. Below is a description of how the. electrical components of your landing. gear behave during a typical ï¬ight.
Set the voltage. Voltage determines height and width of bead. If no chart, manual or specifications are available for setting the correct voltage, you can try this: while one person welds on scrap metal, an assistant turns down the voltage until the arc starts stubbing into the work piece.
Preheat and interpass temperatures determine the cooling. rates that will be experienced by the weld metal and. surrounding steel. The cooling rate must be properly. controlled to ensure that the weld does not crack, and that. the resultant weld metal will have the required properties.
