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.
There are settings for both gas pressure and flow rate. These can vary depending upon the welding position, metal type/thickness, type of gas used, and conditions (wind, drafts etc.) My welding instructor told us that 20-20 is a good place to start (20 psi, 20cfm flow).
