AC
= Alternating Current
Amps = The measurement of the electrical (current) flow.
Arc Blow = A magnetic field that deflects the arc to one side caused by a DC circuit.
AWS = American Welding Society
CFH = Cubic Feet per Hour
CGA = Compressed Gas Association
CSA = Canadian Standards Association
CWB = Canadian Welding Bureau
Constant Current (CC) = a machine that varies its output voltage to maintain a steady current.
DCEP = Direct Current Electrode Positive (Creates a cleaning action with TIG)
GMAW = Gas Metal Arc Welding
GTAW = Gas Tungsten Arc Welding
High Frequency (HF) = The ionization of gas between the electrode and workpiece creating an arc.
Inductance = The rate of current rise.
Inert Gas = A gas that has little or no ability to react chemically.
L/min = Litres per minute.

Constant Current (CC) = a machine that varies its output voltage to maintain a steady current.
Constant
Potential/Voltage (CP/CV) = a machine that will fluctuate its output current to maintain a set voltage.
DCEN
= Direct Current Electrode NegativeDCEP = Direct Current Electrode Positive (Creates a cleaning action with TIG)
Down
Slope = The control of the ending amperage at the moment the arc is
extinguished opposed to the set amperage for welding.
GMAW = Gas Metal Arc Welding
GTAW = Gas Tungsten Arc Welding
High Frequency (HF) = The ionization of gas between the electrode and workpiece creating an arc.
Inductance = The rate of current rise.
Inert Gas = A gas that has little or no ability to react chemically.
L/min = Litres per minute.
MIG = Metal Inert Gas
Ohm = The measurement of resistance in an electrical conductor.
Ohm's Law = E = I x R (Voltage=Current in amps x Resistance in ohms)
Pre-Purge (Pre-Flow) = The flow of gas before the arc is struck.
Post-Purge (Post-Flow) = The flow of gas after the arc is extinguished.
Resistance = The force that prevents the flow of electricity. (Wire size, electrical conductors, etc.)
Reverse Polarity = DCEP
SAW = Submerged Arc Welding
Single-Phase
= An AC current different in phase by 180ยบ
SMAW = Shielded Metal Arc Welding
Stick Welding = Sometimes called Arc welding. With a flux coated stick electrode.
Straight
Polarity = DCEN
Three-Phase = An AC current with 3 single-phase currents timed to start at regular intervals from each other.
Three-Phase = An AC current with 3 single-phase currents timed to start at regular intervals from each other.
TIG = Tungsten Inert Gas
Up
Slope = The control of the starting amperage at the moment the arc is
ignited opposed to the set amperage for welding.
Volts
= Electrical pressure
