the torch end. Turn welder off.
9. Carefully slip the contact tip over the
wire and screw it into the torch neck.
Install the nozzle by turning clock-
wise (See Figure 6). Cut the wire off
approximately 1/4" from the end of
the nozzle.

For gas shielded welding, connect the
cable coming out of the torch to the (+)
socket and the work clamp cable to the
(-) socket on the front panel. For flux-
core (no-gas) welding, connect torch to
(-) and work clamp to (+).
DUTY CYCLE / THERMOSTATIC
PROTECTION
Welder duty cycle is the percentage of
actual weld time that can occur in a ten
minute interval. For example, at a 10%
duty cycle, actual welding can occur for
one minute, then the welder must cool
for nine minutes.
Internal components of this welder are
protected from overheating with an
automatic thermal switch. A yellow
lamp is illuminated on the front panel
if the duty cycle is exceeded. Welding
operations may continue when the
yellow lamp is no longer illuminated.
Welding Helmet
Assembly
MODEL WT1000
1. Remove the lens retainer from the
face shield with a regular screwdriver
by prying against the shield and post
of the lens retainer.
2. Remove the protective film covering
from both sides of each lens cover.
Put one clear lens cover on each side
of the shaded lens. Place these three
lenses together into the face shield
and secure with the lens retainer. The
lens retainer should snap into the
second notch in the face shield.
3. Position one of the holes in the
adjustment arm over the pins which
are located in the ear area of the face
shield. These adjustment arms control
the closeness of fit and can be easily
repositioned if necessary.
4. Position the headgear inside the face
shield. Assemble the helmet by
inserting the stud screw through the
headgear and shield into the tension
nut as shown. Do not tighten tension
nut completely.

comfortable position and lower the
face shield. If the shield is too far or

too close to the face, use a different
hole in the adjustment arm. Adjust

the tension nuts so that helmet can be
easily lowered over the face by

Shielding Gas
Installation
of compressed gas cylinders and
regulators can result in serious injury
or death! Always secure gas cylinders
to the tank bracket kit, a wall or other
fixed support to prevent the cylinder
from falling over. Read, understand,
and follow all the compressed gases
and equipment hazards in the safety
instructions.
NOTE: Shielding gas is not required if
flux-cored welding wire is used.
GAS TYPES
There are 3 types of gas generally used
for gas metal arc welding; 100% argon,
a mixture of 75% argon and 25%
carbon dioxide (C25) or 100% carbon
dioxide. However, 100% carbon
dioxide is not recommended due to
unsatisfactory weld beads. This welder
does not perform well with 100%
carbon dioxide. The 75/25 mixture is
recommended for general steel
welding. For aluminum welding, use
100% argon. Cylinders of either type
gas may be obtained at your local
welding supply outlet. Secure cylinder
in place on your welding machine or
other support to prevent the cylinder
from falling over.
NOTE: Use of incorrect gas may lead to
little or no penetration of welding
electrode (wire).
REGULATOR
The regulator provides a constant
shielding gas pressure and flow rate
during the welding process. Each
regulator is designed to be used with a
specific gas or mixture of gases. The
argon and argon mixture use the same

thread type. The 100% carbon dioxide
uses a different thread type. An adapter
is available at your local welding gas
supplier to change between the two.
