Air Carbon Arc Cutting (CAC-A) - A cutting process by which metals are melted by the heat of an arc using a carbon electrode. Molten metal is forced away from the cut by a blast of forced air.
Alternating Current (AC) - An electrical current that reverses its direction at regular intervals, such as 60 cycles alternating current (AC), or 60 hertz.
Aluminum Pulse Hot Start™ (MTE) - Automatically provides more arc power to the Millermatic® 350P to eliminate a "cold start" that is inherent with aluminum starts.
Amperage - The measurement of the amount of electricity flowing past a given point in a conductor per second. Current is another name for amperage.
Arc - The physical gap between the end of the electrode and the base metal. The physical gap causes heat due to resistance of current flow and arc rays.
Arc-Drive (MTE) - Automatically enhances Stick welding, especially on pipe, by focusing the arc and preventing the electrode from going out.
Auto-Crater™ (MTE) - Allows a TIG arc on the Trailblazer® Series to crater-out, allowing time for the addition of filler, without the loss of shielding gas. Eliminates the need for a remote control at arc end.
Auto-Line™ (MTE) - Allows for any primary input voltage within a range, single- or three-phase, 50 or 60 Hz. Also adjusts for voltage spikes within the entire range.
Auto-Link® (MTE) - Internal inverter power source circuit that automatically links the power source to the primary voltage being applied (230 V or 460 V), without the need for manually linking primary voltage terminals.
Automatic Start at Idle (MTE) - Idles engine immediately when started, extending engine life and reducing fuel consumption and noise.
Automatic Welding - Uses equipment which welds without the constant adjusting of controls by the welder or operator. Equipment controls joint alignment by using an automatic sensing device.
Auto-Refire™ (MTE) - Automatically controls the pilot arc when cutting expanded metal or multiple pieces of metal, without manual re-triggering.
Auto Remote Sense™ (MTE) - Automatically switches machine from panel to remote control with remote connected. Available on Dimension™ NT 450, XMT® 350, Trailblazer® Series, and PRO 300. Eliminates confusion and need for panel/remote switch.
Auto-Stop™ (MTE) - Allows a TIG arc to be stopped without the loss of shielding gas on the Trailblazer® Series.
Axcess™ File Management (MTE) - Software that turns a standard Palm handheld into a data card and a remote pendant for all Axcess systems. Allows e-mailing, storage, and transfer of welding programs.
C
Constant Current (CC) Welding Machine - These welding machines have limited maximum short circuit current. They have a negative volt-amp curve and are often referred to as "droopers".
Constant-Speed Wire Feeder - Feeder operates from 24 or 115 VAC supplied by the welding power source.
Constant Voltage (CV), Constant Potential (CP) Welding Machine - This type of welding machine output maintains a relatively stable, consistent voltage regardless of the amperage output. It results in a relatively flat volt-amp curve.
Cool-On-Demand™ (MTE) - Integrated cooler runs only when needed on Syncrowave® 250 DX & 350 LX.
Current - Another name for amperage. The amount of electricity flowing past a point in a conductor every second.
D
Defect - One or more discontinuities that cause a testing failure in a weld.
Dig - Also called Arc Control. Gives a power source variable additional amperage during low voltage (short arc length) conditions while welding. Helps avoid “sticking” Stick electrodes when a short arc length is used.
Direct Current (DC) - Flows in one direction and does not reverse its direction of flow as does alternating current.
Direct Current Electrode Negative (DCEN) - The direction of current flow through a welding circuit when the electrode lead is connected to the negative terminal and the work lead is connected to the positive terminal of a DC welding machine. Also called direct current, straight polarity (DCSP).
Direct Current Electrode Positive (DCEP) - The direction of current flow through a welding circuit when the electrode lead is connected to a positive terminal and the work lead is connected to a negative terminal to a DC welding machine. Also called direct current, reverse polarity (DCRP).
Dual Power Option™ (MTE) - Gives the option on the PipePro™ 304 engine drive to use 230 volt single- or three-phase electric input power, eliminating engine wear, noise and emissions, as well as fuel costs.
Duty Cycle - The number of minutes out of a 10-minute time period an arc welding machine can be operated at maximum rated output. An example would be 60% duty cycle at 300 amps. This would mean that at 300 amps the welding machine can be used for 6 minutes and then must be allowed to cool with the fan motor running for 4 minutes.
E
Engine Save Start™ (MTE) - Idles engine 3 - 4 seconds after starting on Trailblazer® 275 DC and 302. Extends engine life and reduces fuel consumption.
F

Fixed Automation - Automated, electronically controlled welding system for simple, straight or circular welds.
Flexible Automation - Automated, robotically controlled welding system for complex shapes and applications where welding paths require torch-angle manipulation.
Flux Cored Arc Welding (FCAW) - An arc welding process which melts and joins metals by heating them with an arc between a continuous, consumable electrode wire and the work. Shielding is obtained from a flux contained within the electrode core. Added shielding may or may not be provided from externally supplied gas or gas mixture.
G
Gas Metal Arc Welding (GMAW) - See MIG Welding.
Gas Tungsten Arc Welding (GTAW) - See TIG Welding.
Ground Connection - A safety connection from a welding machine frame to the earth. See Workpiece Connection for the difference between work connection and ground connection.

H
Hertz - Hertz is often referred to as "cycles per second". In the United States, the frequency or directional change of alternating current is usually 60 hertz.
High Frequency - Covers the entire frequency spectrum above 50,000 Hz. Used in TIG welding for arc ignition and stabilization.
Hot Start™ (MTE) - Used on some Stick (SMAW) machines to make it easier to start difficult-to-start electrodes. Used for arc starting only.

Inverter - Power source which increases the frequency of the incoming primary power, thus providing for a smaller size machine and improved electrical characteristics for welding, such as faster response time and more control for pulse welding.
K
KVA (Kilovolt-amperes) - Kilovolt-amperes. The total volts times amps divided by 1,000, demanded by a welding power source from the primary power furnished by the utility company.
KW (Kilowatts) - Primary KW is the actual power used by the power source when it is producing its rated output. Secondary KW is the actual power output of the welding power source. Kilowatts are found by taking volts times amps divided by 1,000 and taking into account any power factor.
