Wire Feed Arc Welder
Glossary of Welding Terms
AC or Alternating Current - electric
current that reverses direction periodically.
Sixty cycle current travels in both directions
sixty times per second.
Arc Length - the distance from the end of
the electrode to the point where the arc
makes contact with the work surface.
Base Metal - the material to be welded.
Butt Joint - a joint between two members
aligned approximately in the same plane.
Crater - a pool, or pocket, that is formed as
the arc comes in contact with the base
metal.
DC or Direct Current - electric current
which flows only in one direction. The
polarity (+ or -) determines which direction
the current is flowing.
DC Reverse Polarity - occurs when the
electrode holder is connected to the
positive pole of the welding machine.
Reverse Polarity directs more heat into
melting the electrode rather than the work
piece. It is used on thinner material.
DC Straight Polarity - occurs when the
electrode holder is connected to the
negative pole of the welding machine. With
straight polarity more heat is directed to
the work piece for better penetration on
thicker material.
Electrode - a coated metal wire having
approximately the same composition as the
material being welded.
Fillet Weld - approximately a triangle in
cross-section, joining two surfaces at right
angles to each other in a lap, T or corner
joint.
Flux - a coating, when heated, that
produces a shielding gas around the
welding area. This gas protects the parent
and filler metals from impurities in the air.

the owner. These MIG items include but are not limited to; Contact Tips, Nozzles, Gun Liners, Drive Rollers, Felt Wire Cleaner. In addition, this warranty does not extend to any damage
caused by the untimely replacement or maintenance of any of the previously listed CONSUMABLE parts.
D. Any failure that results from accident, purchaser's abuse, neglect or failure to operate products in accordance with instructions provided in the owner's manual(s) supplied with the
product.
E.
Pre-delivery service, i.e. assembly and adjustment.
7.
Responsibilities of Warrantor under this warranty: Repair or replace, at Warrantor's option, products or components which have failed within duration of the warranty period.
8.
Responsibilities of purchaser under this warranty:
A. Deliver or ship the Campbell Hausfeld product or component to Campbell Hausfeld. Freight costs, if any, must be borne by the purchaser.

Flux Cored Arc Welding (FCAW) - also
called Gasless, is a welding process used
with a wire-feed welding machine. The
weld wire is tubular with flux material
contained inside for shielding.
Gas Metal Arc Welding (GMAW) - also
called MIG, is a welding process used with a
wire feed welding machine. The wire is
solid and an inert gas is used for shielding.
Gas Tungsten Arc Welding (GTAW) - also
called TIG, is a welding process used with
welding equipment with a high frequency
generator. The arc is created between a
non-consumable tungsten electrode and
the work piece. Filler metal may or may not
be used.
Lap Joint - a joint between two
overlapping members in parallel planes.
Open Circuit Voltage (OCV) - the voltage
between the electrode and the work clamp
of the welding machine when no current is
flowing (not welding). The OCV determines
how quickly the arc is struck.
Overlap - occurs when the amperage is set
too low. In this instance, the molten metal
falls from the electrode without actually
fusing into the base metal.
Porosity - gas pockets, or cavities, formed
during weld solidification. They weaken the
weld.
Penetration - the depth into the work
piece that has been heat effected by the arc
during the welding process. A good weld
achieves 100% penetration meaning that
the entire thickness of the work piece has
been heated and resolidified. The heat
effected area should be easily seen on the
opposite side of the weld.

Shielded Metal Arc Welding (SMAW) -
also called Stick, is a welding process with
uses a consumable electrode to support the
arc. Shielding is achieved by the melting of
the flux coating on the electrode.
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.
