3. Convert your measurement into amperes. Each 100th of an inch of metal requires one ampere.
Instructions
1. Degree the thickness of the metals you are joining well-balanced using calipers and a ruler.
2. Change the standard measurement into decimals by dividing the numerator by the denominator. For instance, if your plate is 1/8 inch thick, divide One by Eight to receive 0.125 inch.
Improperly setting the provisions hurry on your MIG welder Testament crop in fragile weld joints or target you to burn a gap in your metal.Metal inert Gauze (MIG) welding machines automatically provisions wire on ice the torch attitude of the welding gun to the weld location. This wire acts both as the electrode that arcs with the metal life welded to constitute the weld bead and as filler facts to blend the metal pieces. To make safe a Correct Seam is created, the MIG wire must be fed to the weld at an hire celerity. Therefore, 1/8 inch thick metal requires One hundred twenty five amps to properly weld the joint.4. Identify the diameter of the MIG wire that you will be using for your weld. The wire manufacturer lists a wire burn rate in inches per ampere on the packaging. For instance, the 0.030 gauge wire required of One hundred twenty five amp welding has a burn rate of Two inches of wire per One hundred twenty five amps.
5. Multiply the required amperage of your weld by the burn rate associated with the diameter of the wire to calculate the feed speed. Using our example, you would multiply the One hundred twenty five amps by the Two inch burn rate to calculate a feed speed of Two hundred fifty inches per minute.
