Technical Vocabulary
(Technical Vocabulary is currently
under construction. Thank you for your patience.)
A
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. To remove large amounts of metal, look for a
welder that can use carbons of at least 3/8 in diameter.
Consumables: carbon electrodes, compressed air supply.
Alternating Current (AC) - An electrical current that
reverses its direction at regular intervals, such as 60 cycles
alternating current (AC), or 60 hertz.
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 Force - Also called Dig and 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.
Auto-Link ® - Internal inverter power source circuit that
automatically links the power source to the primary voltage
being applied, without the need for manually linking primary
voltage terminals.
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.
