Shielded Metal Arc Welder
Glossary of Welding Terms
AC or Alternating Current - electric Flux Cored Arc Welding (FCAW) -
current that reverses direction also called Gasless, is a welding process
periodically. Sixty cycle current travels used with a wire-feed welding
in both directions sixty times per machine. The weld wire is tubular with

of the electrode to the point where the Gas Metal Arc Welding (GMAW) -

Slag - a layer of flux soot that protects
the weld from oxides and other
contaminants while the weld is
solidifying (cooling). Slag should be
removed after weld has cooled.
Spatter - metal particles thrown from
the weld which cool and harden on the
work surface. Spatter can be minimized
by using a spatter resistant spray on the
work piece before welding.
Tack Weld - weld made to hold parts
in proper alignment until final welds
are made.
Travel Angle - the angle of the
electrode in the line of welding. It
varies from 5º to 45º depending on
welding conditions.
T Joint - made by placing the edge of
one piece of metal on the surface of
the other piece at approximately a 90º
angle.
Undercut - a condition that results
when welding amperage is too high.
The excessive amperage leaves a
groove in the base metal along both
sides of the bead which reduces the
strength of the weld.
Weld Pool or Puddle - a volume of
molten metal in a weld prior to its
solidification as weld metal.
Weld Bead - a narrow layer or layers of
metal deposited on the base metal as
the electrode melts. Weld bead width is
typically twice the diameter of the
electrode.
Work Angle - the angle of the
electrode from horizontal, measured at
right angles to the line of welding.

Descripción
Esta soldadora con arcos revestidos de
Campbell Hausfeld está diseñada para
usarse con corriente doméstica de 115V
estándar. Está equipada con un control
de salida para seleccionar con precisión
la corriente adecuada necesaria para
varias condiciones de soldadura. Los
componentes internos tienen un
sistema de protección termostática.
Esta soldadora le permite soldar acero
de hasta 3,2 mm(1/8") de grosor en un
sólo paso. Le recomendamos que utilice
electrodos de 1,6 mm (1/16") de
diámetro cuando utilice 15 amperios y
electrodos de hasta 0,08 mm (5/64")
cuando utilice 20 amperios, en EE.UU.
