Mig welding overhead is mostly a matter of getting comfortable. Again, POSITION.
The same settings and techniques that are used for flat and horizontal also work on overhead. But if you typically weld really hot, reducing the wire speed by 10% might help.
In some industries, a certain look is expected for MIG welds. For example, the motorsports industries has adopted the "MIG like TIG" look.
It involves using settings different from what is normally used for production. Wire speed in particular is usually much lower, which lowers the overall trav...
MIG welding thin wall square tubing in a common fixed position.
MIG welding uphill requires lower settings. A pro tip is to just use the chart or auto settings for thinner metal ( 2 thicknesses usually works well).
