dust or dirt that may have
accumulated around valve seat.
2. Install regulator onto cylinder valve
with face of gauges in the vertical
position. Tighten stem nut securely to
gas valve.
3. Install one end of gas hose to fitting
on the rear of welder and other end
of hose to fitting on regulator using
hose clamps on each connection. Make
sure gas hose is not kinked or twisted.
4. While standing opposite cylinder
outlet, slowly open cylinder valve.
Inspect for leaks in the connections.
5. Pull trigger on gun to allow gas to
flow. Adjust gas regulator to
maximum flow. Release trigger.
6. Remember to close gas valve when
finished welding.
The welding wire is
live whenever the
welder is turned on - whether the trigger
is pulled or not.
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. Position Heat Selector on front panel
to desired setting.
NOTE: These settings are general
guidelines only. Heat setting may vary
according to welding conditions and
materials.

6. Rotate Wire Speed Control to setting
number 5 to start then adjust as
needed after test weld.
7. Plug power cord into a proper
voltage receptacle with proper circuit
capacity (See circuit requirements on
front page).
8. Switch welder ON/OFF switch to ON
position.

9. Verify wire is extended 1/4" from
contact tip. If not, squeeze trigger to
feed additional wire, release trigger
and cut wire to proper length.
10. Position wire feed gun near work
piece, lower welding helmet by
nodding head or position the hand
shield, and squeeze gun trigger. Adjust
heat setting and wire speed as needed.
11. When finished welding, turn welder
off and store properly.
Maintenance
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
2. Check condition of power cord and
3. Inspect the condition of the gun tip
with cracked or missing insulation on
welding cables, wire feed gun or power
cord.
EVERY 3 MONTHS:
1. Replace any unreadable safety labels
2. Use compressed air to blow all dust

3. Clean wire groove on drive roll.

Consumable and Wear Parts
The following parts require routine
maintenance:
• Wire feed drive roller
• Gun liner - replace if worn
• Nozzle/contact tips
• Wire - This welder will accept either 4"
or 8" 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 months. For mild steel
welding, AWS ER70S6 solid wire or AWS
E71T-GS Flux-core wire is recommended.
