KNOW YOUR WELDER
Handle– Rugged, top mounted handle
allows for easy transport of your welder.
Wire Speed Control– Use this dial to
adjust the speed at which the welder feeds
wire to the gun. 1 is the slowest wire feed
speed, 10 is the highest. You will need to
adjust or “tune-in” your wire speed for dif-
ferent welding conditions (thickness of met-
als, gas -vs- gasless welding, metal type,
wire size, etc.). When the wire speed is prop-
erly “tuned-in” the welding wire will melt
into the material you are welding as quickly
as it is fed through the welding gun.
VoltageSelector– This four position dial
adjusts the voltage or “heat” of your welder.
1 is the lowest and 4 is the highest.
materials and material thickness will require
voltage settings. You will need to
adjust your voltage accordingly for
welding conditions. By properly adjusting
your voltage settings and wire feed speed,
you will enable clean, precision welds. (Refer
to the Suggested Settings Chart on p.33 of
this manual OR on the inside of the door of
the welder.)
Power Switch– This switch turns the welder
ON and OFF.
(Make sure the power switch is
in the OFF position before performing any
maintenance on the welder.)
PowerCord – This is a standard, grounded
120 volt power cord. (Make sure you are
using a properly grounded 120V AC, 60 Hz,
single phase, 20 Amp power source.)
Ground Clamp – Attaching the ground
clamp to your work piece “completes” the
welding current circuit. You must attach the
ground clamp to the metal you are welding.
If the ground clamp is not connected to the
metal work piece you intend to weld, the
welder will not have a completed circuit and
you will be unable to weld. A poor connec-
tion at the ground clamp will waste power
and heat. Scrape away dirt, rust, scale, oil or
paint before attaching the ground clamp.
Ground Cable – The ground cable connects
the ground clamp to the internal workings of
the welder.
Welding Gun and Cable – The welding
gun controls the delivery of
the welding wire
to the material to be welded. The welding
wire is fed through the welding cable and
welding gun when the welding gun trigger is
pulled. You will need to install a contact tip
and welding nozzle to the end of the weld-
ing gun, as described later in
this manual,
prior to welding.
Now that you are familiar with the main
parts of the welder, make note of the follow-
ing terms. You will see them used through-
out this manual.
Weld puddle: The localized volume
of molten metal in a weld prior to its
Figure 1.
Weld angle: The angle of the welding wire,
as it extends from the welding gun, in rela-
tion to the item being welded.
Slag: The protective coating that forms on
the surface of molten metal.
Arc: A sustained luminous discharge of elec-
tricity across a gap in a circuit.
Welding bead: The extended build up of a
weld, made by pushing or pulling the weld
puddle.
