The types of MIG welding include short circuit transfer, globular transfer, spray transfer, and pulsed spray transfer.

• Short circuit transfer: Uses low voltage and creates a short circuit between the electrode and the workpiece.

• Globular transfer: Involves larger droplets of molten metal being transferred across the arc.

• Spray transfer: Uses high voltage to create a spray of tiny molten droplets.

• Pulsed spray transfer: Alternates between high and low voltage to control the transf...read more
