If you’re a welding hobbyist making basic repairs in your shop or garage, or a welding professional who’s laid miles of bead over the years, improving your skills will help you maximize efficiency and quality, while minimizing costs in repair and labor. We have collected the best information and education for your machines or outfits and organized them here at your fingertips.

MIG Welding (GMAW or Gas Metal Arc Welding) - Also referred to as solid wire welding. An arc welding process which joins metals by heating them with an arc. The arc is between a continuously fed filler metal (consumable) electrode and the workpiece. Externally supplied gas or gas mixtures provide shielding. There are four basic modes of metal transfer: Short Circuit Transfer, Globular Transfer, Spray Transfer, and Pulsed-Spray Transfer.
TIG Welding (GTAW or Gas Tungsten Arc) - Often called TIG welding (Tungsten Inert Gas), this welding process joins metals by heating them with a tungsten electrode which should not become part of the completed weld. Filler metal is sometimes used and argon inert gas or inert gas mixtures are used for shielding.
Stick Welding (SMAW or Shielded Metal Arc) - An arc welding process which melts and joins metals by heating them with an arc, between a covered metal electrode and the work. Shielding gas is obtained from the electrode outer coating, often called flux. Filler metal is primarily obtained from the electrode core.
Plasma Arc Cutting - An arc cutting process which severs metal by using a constricted arc to melt a small area of the work. This process can cut all metals that conduct electricity.
Oxy-Fuel Cutting & Welding
Oxy-fuel welding & Cutting(commonly called oxyacetylene welding, oxy welding, or gas welding) and oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals.
