What is a Good Weld?
What goes into a good weld? Find out how to consistently get proper bead size and height with this helpful poster. Identify common welding issues related to travel speed (too fast/too slow), arc (voltage too high/voltage too low) and amperage (too much/too little).

When it comes to choosing the right MIG transfer process for your application, there are many variables to consider. How thick is the metal? How important is a good bead? How will the final product be used? Get answers with this handy guide.View Miller Welding's MIG Process Guide (PDF)
GMAW-P (Pulsed MIG)
Scenario: A baseline weld was made using automated welding equipment. Voltage, wire feed speed, travel speed and contact-tip-to-work distance were then adjusted individually from baseline weld settings to illustrate how each parameter affects a fillet weld when raised and lowered. See the results in this simple breakdown.View Miller Welding's GMAW-P Guide (PDF)
