Wire Feed Arc Welder
Operation
1. Be sure to read, understand
and comply with all
precautions in the General
Safety Information section.
Be sure to read entire
"Welding Guidelines" section before
using this equipment.
2. Turn welder off.
3. Verify 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 operating this equipment or
in the area while equipment is in use
must wear protective welding gear
including: eye protection with proper
shade, flame resistant clothing, leather
welding gloves and full foot protection.
If heating, welding or cutting
galvanized, zinc plated, lead,
or cadmium plated materials,
refer to the General Safety
Information Section for instructions.
Extremely toxic fumes are created when
these metals are heated.
4. Connect work clamp to work piece or
workbench (if metal). Make sure
contact is secure. Avoid surfaces with
paint, varnish, corrosion or non-
metallic materials.
5. Rotate Wire Speed Control to setting
per decal inside wire feed
compartment, then adjust as needed
after test.
6. Plug power cord into a proper
voltage receptacle with proper circuit
capacity (see circuit requirements on
Page 1).
7. Switch welder on to desired heat
setting per decal inside wire feed
compartment, then adjust as needed
after test.
NOTE: These settings are general
guidelines only. Heat setting may vary
according to welding conditions and
materials.
8. Verify wire is extended 1/4 in. from
contact tip. If not, squeeze trigger to
feed additional wire, release trigger,
turn welder off, and cut wire to
proper length. Then, switch back on
to desired heat setting.

NOTE: The welder transformer is off and
will not energize until the trigger is pulled.
This is a "cold torch" welding machine and
it will not weld until the trigger is pulled.
MANUAL
9. Position torch near work piece, lower
welding helmet by nodding head or
positioning the hand shield, and
squeeze torch trigger. Adjust heat
setting and wire speed as needed.
10. When finished welding, turn welder
off and store properly.
Maintenance
Disconnect power supply and turn
machine off before inspecting or
servicing any components. Keep wire
compartment cover closed at all times
unless wire needs to be changed.
BEFORE EVERY USE:
1. Check condition of weld cables and
immediately repair or replace any
cables with damaged insulation.
2. Check condition of power cord and
immediately repair or replace any
cord if damaged.
3. Inspect the condition of the torch
contact tip and nozzle. Remove any
weld slag. Replace torch contact tip
or nozzle if damaged.

missing insulation on welding cables,
torch or power cord.
EVERY 3 MONTHS:
1. Replace any unreadable safety labels
on the welder.
2. Use compressed air to blow all dust
and lint from ventilation openings.
3. Clean wire groove on drive roller.
Remove drive roller and use a small
wire brush to clean. Replace if worn
or damaged.
Consumable and Wear Parts
The following parts require replacement:
• Wire feed drive roller
• Torch liner
• Nozzle/contact tips
• Wire - This welder will accept either 4
in. or 8 in. diameter spools. Flux-
Cored welding wire is susceptible to
moisture and oxidizes over time, so it
is important to select a spool size that
will be used within approximately 6
Supply Cable Replacement
1. Verify that welder is OFF and
2. Remove welder side panel to
3. Disconnect the power cord leads
4. Disconnect the ground wire
5. Loosen the cord strain relief screws
6. Install new cord in reverse order
CHANGING WIRE SIZES
This welder is setup for .030 in. (0.8
mm) wire. If a different wire size is
used, the wire feed drive roller and
contact tip may need changing. There
are two grooves in the drive roller. The
small groove is for .024 in. (0.6 mm)
MIG wire and the large groove is for
.030 - .035 in. (0.8 - 0.9 mm) flux core
and MIG wire. Rotate the tension knob
down and swing arm up. Remove roller

flip the drive roller to choose the
correct groove. The contact tip should
also match the wire diameter used. The
tip diameter is marked on the contact
tip in inches and/or millimeters.
