| Self- Shielding Electrode | an electrode that produces its own shielding gas and does not require additional shielding gas |
| Short Circuiting Transfer | a gas metal arc process that uses relatively low voltage. The arc is constantly interrupted and restarted as the molten electrode shorts out against the base metal. |
| Pulsed Spray Transfer | a GMAW process in which the current is pulsed to take advantage of the spray mode of metal transfer, but with current values below the spray transition current. |
| Metal Cored Electrode | an electrode that has a mild steel sheath over a core that contains iron powder and other metal alloy powders. |
| Pinch Force | in short circuiting GMAW metal transfer, the magnetic force that squeezes off the droplet of the molten electrode metal. |
| Push- Pull System | a system formed when a GMAW pull gun pulls the electrode wire through the cable and the wire feeder pushes the wire. |
| Microprocessor | a silicon chip that contains computer logic circuits and other components used to control a digital device. |
| Short Circuit | in the short circuiting transfer process, the condition that occurs when the electrode touches the base metal, causing metal from the electrode to enter the weld. |
| Liner | a fl exible tube placed inside the combination cable through which a consumable wire electrode passes on its way to the GMAW torch. |
| Globular Transfer | in GMAW, the movement of molten metal in large droplets from the consumable electrode across the arc. |
