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.
Equipment Preparation. 1  Check your cables: Before striking an arc, check your welding equipment to make sure all of the cable connections are tight fitting and free of fraying or other damage. 2  Select electrode polarity: MIG welding requires DC electrode positive, or reverse polarity. The polarity connections are usually found on the inside of the machine. Set gas flow: Turn on the shielding gas and set the flow rate to 20 to 25 cubic feet per hour.
