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.
The polarity used is also standard and that is D/C electrode (+) positive. This means that the handle is the positive side of the circuit, or it may be said, the electricity flows from the metal in to the welding handle. The power source used for MIG welding is called a âconstant voltage power supplyâ.
