MIG Welding Tips and Tricks
MIG Welding Tips
1. Direct your wire at the leading edge of your weld pool for the most control of
your weld bead.
2. For the most bead control when doing more difficult welds such as; Vertical,
horizontal, and overhead welds, use the smallest wire diameter possible, and
keep you weld pool small.
3 Your contact tube, gun liner, and drive rolls should coincide with your wire.
4. Keep your gun liner, drive rolls, and gun nozzles clean. Contact tips should be
replaced if there is blockage, or not feeding the way it should.
5. Your gun should stay straight, ensuring the wire will feed properly.
6. Steady the gun with both hands.
7. Do not over tighten wire feeder hub tension and drive roll pressure.
8. Store your wire in a place that is contaminant free.

do your weld will not be correct.
