How To Use Welding. This is easy MIG welding techniques require you to use a reverse polarity DC electrode positivity on some machines. Attach the work lead to the workpiece and hold the gun so the wire meets the weld surface at about a 30-degree angle.
Set the flow rate to around 20-25 cubic feet an hour and make sure that the gas is switched on. Youll find these settings typically on the interior of the machine. This is easy MIG welding techniques require you to use a reverse polarity DC electrode positivity on some machines.
Connect the metal you want to weld together and put on a pair of welding gloves and goggles to be safe.
When welding a 90 degree joint angle your weld gun about 45 degrees and aim the weld wire at the point the two pieces of metal meet.
