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.
VRD stands for voltage reduction device. When a VRD is fitted to a welding machine it reduces the maximum unloaded open circuit voltage across the output terminals of the welder to a safe voltage normally this reduced voltage is about 12 volts (Australian Standards 1674.2 2003 state this voltage must be less than 35 Volts DC and 25 Volts AC).
