Shielded Metal Arc Welder
Assembly

3. To attach the handle, place shield on
a flat surface and press handle into
place (See Figure 5).

NOTE: If you have never welded before
or have little experience, a full face
helmet is recommended. Both hands
are needed to stabilize and control the
angle and arc length of the electrode.
Operation
1. Be sure to read,
understand, and comply
with all precautions in
the General Safety
Information section. Be sure to read
the entire section entitled Welding
Guidelines prior to using this
equipment.
2. Turn welder off and plug into
appropriate receptacle:
115v-15 amp - Low
115v-20 amp - High
3. Verify that the surfaces of metals to
be joined are free from dirt, rust,
paint, oil, scale or other contaminants.
These contaminants make welding
difficult and cause poor welds.
All persons
WARNING
!
operating this
equipment or in the area while
equipment is in use must wear protective
welding gear including: eye protection
with minimum shade 10 lens, flame
resistant clothing, leather welding
gloves, and full foot protection.

WARNING
!
If heating, welding, or
cutting materials that are
galvanized, zinc plated, lead,
or cadmium plated refer to the General
Safety Information Section for
instructions. Extremely toxic fumes are
created when these metals are heated.
4. Connect the work clamp to the
work piece. Make sure the contact is
on bare metal and not obstructed
by paint, varnish, corrosion, or non-
metallic materials.
5. Insert the exposed part of the
electrode rod (the end with no flux)
into the jaws of the electrode
holder.

surface may produce an arc which could
cause sparks and damage eyesight.
6. Hold the electrode away from the
MANUAL
grounded work piece or
workbench. Turn on the welder to
either High or Low. Refer to the
following chart for proper output
setting.

Diameter
1/16 in. (1.6 mm)
5/64 in. (2 mm)
7. Position the electrode to begin
weld, lower the welding helmet or
position the hand shield, and strike
an arc. Adjust output setting as
needed.
8. When finished welding, turn welder
off and store properly.
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.
Maintenance
The electrode
holder and rod are
machine off before inspecting or
servicing any components.
