MIG welding tip

When setting up your MIG welder, first take a look at how thick the metal is that you’re welding. Is your welder large enough to weld this thickness? And is the machine set up correctly to complete the weld? With Miller’s Auto-Set™ feature (available on most Millermatic® products), you simply set the wire size and the material thickness and you’re ready to go!

Make sure you use the correct type of gas and that you’ve turned the bottle on. C-25 or Argon CO75/25 is the most common gas used. It should be set for 30 CFH for the best results. And, don’t forget to make sure you have the polarity set correctly for the type of wire you are using.

Lastly, a common mistake is trying to weld a continuous line. Try welding in an X-pattern – upper left, lower right, then upper right and lower left.
